I'm Running a Triathalon for Leukemia Please Support

It's Tax Deductible!!! And it feels good!

Just finished Audio Project Phase 1 (Maxxine 05)

Year: 2005 - Make: Chevy - Model: Malibu Maxx

Christmas weekend ('09) I designed and fabricated a custom individually sealed enclosure housing four 8" Rockford P1 subwoofers including amp rack. The subs are powered by Fijitsu Ten Eclipse amplifier 2 Channel 600 watts RMS. I also installed two pair of Rockford components 6.5" (front doors), 5.25" (rear doors) T1 Power Series and 6x9" Power series (cargo area). Mid-Randge and tweeters powered by 600 watt Power series 4 channel Rockford Fosgate amplifier (set on display on rack). Pictures pending ...

Changing 2005 Malibu Maxx Light Bulb

My tail light went out so I have to change it. Here is a easy way to replace your blown bulb in your 2005 Maxx ... I call her "Maxxine". http://ping.fm/Y2Exv

1 Year MECP Certified But No Job in the Industry ... I Guess T-Mobile will Do.

When I graduated from trade school I thought I had lined up a job at Tweeter and the next thing you know the whole company croaked. It was due time that Circuit City blew it's fuse do to poor strategic management.

12 Volt is not dead we just have to establish a strategic plan! If there are any shop owners / managers out there looking for a multi-talented team member that is going to contribute the growth of your business contact me. I am willing to work in the field, whether it is installing or business operations.

... and many more

Currently working at T-Mobile as a sells representative.

I have had my MECP Certification for a year and I have not worked in a shop yet. The industry will and has to go on but in the mean time I need to get some notches on my belt. So far I have had the opportunity to install a head-unit here, iPod interface there, add a fog light here, a sub woofer there, and my own project in the parking lot.

I know this blog was a little choppy but I am working on it. Will try to add more media later on and sharpen the writing skills.

Another Milestone Thank You ALL!!! - (My Work Published in a PAS Magazine CES issue MTT Tech)

Hello Family and Friends,

First and foremost, I want to thank all of you who have supported me in the last 5 years through Towson University and Mobile Technical Training. Without your support I would not have been able to accomplished all that I have done today. Whether your contribution was family support, your friendship, tennis coaching, on the court, in the classroom (professors, teachers, classmates), though my LAMBDA Family, or in the garage let be known to you all that I truly appreciate EVERYTHING!

With that said, I would like to give you an update on my progress thus far.

First, I am scheduled to graduate with my e-Business degree from Towson University in January 2009 for class of 2008. Since graduating from high school I have also graduated from trade school at Mobile Technical Training in Summer 2008 and became a Mobile Electronic Certified Professional and trained Trimmer (upholstery).

In addition to becoming a more educated individual, I have also served as a board member and general member of several organizations (Resident Assistant 2005-2008, Black Student Union, Latin American Student Organization, LeaderShape 2005, Diversity Retreat 2008, Electronic Business Association, University Residence Government, ...), created new events on Towson's Campus and become a founding brother of Lambda Theta Phi, Latin Fraternity Inc. at Towson University (Towson Colony).

Just know that somehow you have contributed to the fulfillment of many major goals and aspirations that I have set since I was a sophomore in high school. Thank You!!!

Justin Juether's Kick Panel Project - Summer 2008 @ MT2

Oh yes, he is nice with it! Don't sleep on this install because he also has an huge custom sub-woofer enclosure with 6 - 10" Rockford P3s that hit about 170 dB in the shop. You could feel pressure your internal organs sitting in the car.

The above photo is not mine, however, Justin H. was a good classmate of mine who also completed a kick panel project.

Read a BOOK!!! ... Knoweledge goes a long way.

TopDog08 says:
"Hey my people, whats goin on out there in the automtive custom world??? Well as 4 me, Im out here tryna be innovative and proactive in this business. Studying, working, installing, creating. I just wanna pass off one of my lil secrets to whoever wants to listen, It's not for everyone, this is just what works for me. READ A BOOK!!!!!!!!!!!!! Man books are just the best things in the world for us. If ur planning on making a career of this, there is a hell of a lot of information out there that ur gonna wanna know. Here's a lil sample of the library that I've built since I started my training at MT2 and after I graduated.
MECP study guide Basic Installation
MECP study guide Mobile Product Specialist
High Performance Car Stereo
Car Stereo Cookbook
Basic Electronics
Understanding Automotive Electronics
Delmar ASE A-6 study manual
Basic Electronics Math............ and I'm buying an average of 2 books a week now. I read whatever I can. It really helps me learn."

My reply:

"That is very true my man. I have a little library myself including some of the books that you have as well. I started by reading Crutchfield stuff online including the beginner stuff.

Knowledge is power ... Power = Current * Voltage

More POWER ... Better QUALITY SOUND ... More CASH

Knowing how to do it and make it work EFFICIENTLY .... PRICELESS!

Books are made of paper ... money is too with a little bit of cotton!!!"

Challenges at MT2

There are some things we have been introduced to in class that may seem overwhelming. Thus far I would have to say that the most challenging topics have been:

Electronics
* Relays
* Alarms

Upholstery
* Steering Wheel
* Conquering those damn RAPID FIRE Sewing Machines

I don't know about you, but I have challenged myself to work the hardest in the most challenging areas. What a better opportunity than to mess up on a project and have an opportunity to get help on the spot than at MT.

I figured that loan I took out is too much for me not to understand how to make a steering wheel, so this is what I did ...Yes, the first student to complete a steering wheel in class! ... Well a steering wheel cover.

"What in the world are you doing?" you ask. .... Project: DA_HULK!!!

I have a 1996 Chevy Lumina, I call it Da_Hulk ... yeah it is a complete sleeper until you see what's in it. It is obivious that I don't drive this car because of its speed. Da_Hulk is all looks, all Sound Quality, no Go ... that is what I am going for. I'd rather get a ticket for disturbing the peace. Check out what I am starting off with at www.juanromerojr.com . As far as the system is concerned, I am upgrading the powerhouse, new component speakers powered by 4-way amp and starting the plans for a sub enclosure, amp racks and lighting for the trunk. * 2 Kinetik HC-1400 Batteries ( - one under the hood for the car's stock components and second in the trunk separate for audio/video. * Stinger 200 Amp Isolator * Run 0 Gauge Wire * Install circuit breakers * Fix rocker switch panel for lighting * Re-wire all of the old components including head unit, lighting and video. * Solder all wires possible * 5 band Arc Audio EQ (XEQ) custom install in plexi-glassed center console * Capacitor in center console * Rockford Fosgate Power Series 4-Channel 600 Watt Amplifier (T600-4) under the front seat * Plexi-Glass display with green L.E.D. & Diamond Cut in center console * Run power wire for accessories to front console distribution block (for 2 Fahrenheit monitors, Playstation 2, lighting) *2 Fahrenheit 7" Monitors * 5.25" Component Rockford Fosgate Speakers (T152s) * 6.5" Component Rockford Fosgate (T162s) * 6x9" 3-Way Coaxial Rockford Fosgate (T1693c) I will get the EQ, subs, amp and capacitor later. That would be a simple install. For that I want to hide the sub facing the rear seat and port the box half way into the car and half way into the trunk area. I want to make a rack for the capacitor and amplifier that will look as if they were floating on illuminated plexi-glass behind a covered beauty board matching the interior seats. In the future I am planning to upgrade some of the upholstery including the headliner, door panels and seats. For the seats and panels I want to put in black vinyl with green suede inserts. ... we will see how that goes. Check out my blog to see the progress ... right now I am in the beginning stages because we all are still waiting for Rockford to ship ... we all know how that is! 3-4 weeks! It will get here sooner or later. Let me know what you think! jr.paperstaxxx@gmail.com www.juanromerojr.com Holla at me!!!

Reading is Fundamental!!!

I am going to take a little break to finish reading this Mobile Product Specialist Study Guide three times over so I can take the exam within the next week or two. Stay tuned for more photos in my slide show above from the upholstery project and some of the fabrication that will be taking place in the HULK Project.

It's Box Building & Fabrication Time!!!

Since taking the MECP exam we have moved on to box building and fabrication. It is all hands on from here ... or so we thought...

The first day was spent going over geometry and algebra required to find dimensions of different shapes. these basic concepts will be used to help us construct subwoofer enclosures that are most effective for a given driver (speaker or subwoofer). We also went over several electrical and phycial properties of a speaker that goes beyond your day-to-day application, basically a bunch of engineer jargon called Theile-Small Parameters.

BOX BUILDING
Using basic geometry we covered in class including area and volune:

Circle / Cylinder:
Area = π*r^2
Volume = π*r^2*l

Square:
Area = s^2 or s*s
Volume = H*W*L

Rectangle / Square:
Area = H*W
Volume = H*W*L

Triangle:
Area: .5B*H
Volume: .5B*W*L

Parallelogram:
Area = H*W*L

Trapazoid:
Area = (B+T/2)*H*W

Combination Box:
Area = [((B+T)/2)*L*(H-F)]+(B*F*L)

If you don't understand what you just read ... don't worry about it that is my job. However, if you are interested just look it up online.

Upon the completion of the math and engineer vocabulary portion we moved to physics. Our instructors explained to us how different types of enclosures work and what makes each enclosure type different. Amazingly enough, I found that your enclosure is just as important as your driver! A correct box could make up to a +12 dB difference. Trust me, I found out the hard way!

Different Types of Enclosures (As discussed in class.)*

• Sealed - a.k.a "Acoustic Suspension"
• Ported
  
• Transmission Line
  
• Bandpass
  
• Isobaric
  

*There are many more enclosures out there, these are amongst the most common types.

After the algebra and geometry lesson we then applied the formulas to real life applications. Here is an example that we went over in class:

ex: Sealed Enclosure w/ One 10" Driver (Subwoofer)
Sealed Volume: 0.9 ft cubed
Speaker Displacement: 0.2 ft cubed
Mounting Diameter: 9.25 in.
Speaker Depth: 7.2 in.
Wood Thickness: 3/4 in.

A few things we have to keep in mind.
* Include the thickness of the wood in our calculations, including ports etc.
* Leave at least 1" behind the port hole for proper ventilation when looking at mounting depth
* Remember how many drivers you are putting into a given enclosure.

Now here were the steps to calculate the correct enclosure dimensions.
1. Obtain speaker specifications (Theile-Small Parameters) ... good sub woofers include these specifications, so if you don't have them or can't find them you should STEP YOUR GAME UP!
2. Add up the enclosure volume and speaker displacement.
3. Convert total from Step 2 into total cubic inches (in^3) by multiplying by 1728
3b. Add port volume including wood.
4. Draw your enclosure design.
5. Choose a height and width that fits the vehicle and /or speaker.
6. Account for wood thickness. (We use 3/4 inch MDS board)
7. Multiply inside dimensions.
8. Divide the total cubic inches by your answer from Step 7 (Internal volume).
9. The answer will give you the inside length (depth) of the box.
10. Be sure the speaker fits in your dimensions with at least an inch of room to allow air flow for the port hole of the driver.
11. Measure and cut the wood.

Front / Back = OH x OW Top / Bottom = OW x OL Left / Right = IL x IH

12. Add to width for design if desired. (i.e. lip - makes for easier carpeting or wrapping).

In the end you get something like this ....


Anyways, after all the fundamental box building techniques we began FABRICATION!!! This includes fiberglass, molding, sculpting, capentry, and how to repair and work with different types of plastics.

FABRICATION ...
Only posting pictures for this portion. This is just a summary of what we covered.

In fabrication we discussed the different types of cleaners and how to maintain tools. Most importantly we learned the mixing ratios for the many chemicals used in fiberglass, foam, body filler, dura-glass, silicone rubber, clear polyester resin, carbon fiber, and several different types of epoxy. Our instructors spent a good amount of time going over mixing ratios and precautions to take when working with such materials.

Needless to say, don't sniff or taste this stuff. Fiberglass itches A LOT if you rub it against your skin (use baby powder prior to working with fiberglass and wash with cold water to close pours). Too much hardener can cause hot stuff called FIRE ... be careful!

We also learned a little bit of arc welding from our instructor Ray Olvera. Arc welding is basically involves the use of high current to melt metal into a liquid state so that they can be combined into one, creating one solid structure. With the electrical current we are directly shorting the peices of metal, touching positive (out torch) ot ground (our structure connected to the negative).

I must say that only experience will help you along with fabrication because you will mess up. The wrong mixing ratio between resin and hardener could cause a fire ... this stuff get HOT!!! So be careful out there, working with fiberglass related chemicals can be very flammable.There are many techniques you either learn or create along the way when creating frames, sculpting shapes and sanding.

NOTE TO THE READER ...

I need to know if someone is really reading this so if a kind heart can just shoot me a reply that would be great. Ask a question or something ... help me help help you.

Thanks for reading!!!

Juan Romero ... Basic MECP Technician

What's up Everyone!!!


I have been gone for a minute studying and everything for the MECP Test and I have good news.

"Juan Romero Jr. i now a Mobile Electronic Certified Professional Technician!!!"

Not only did I pass my exam I aced it! I would like to congratulate the rest of my classmates who also passed the exam.

My certificate is at my Aunt's house right now. All I have to get now is a nice button up to apply my MECP badge! If you are borred check out my resume at http://www.juanromerojr.com and click on "Resume". It is in the works so just download the .pdf version. ... Right now I am writing my resume in raw html for the website so bear with me on that one.

Now I am reading the Mobile Product Specialist book and I am planning to get the Silver Level / Advanced book so I can get ready for those two tests. Let's get it!!!

MECP - Practice Exam Link

The MECP test is coming soon and I have to review everything that I have been studying. My goal is to score a solid 100 percent on each section. ... Some say that is not feasible, but do you know what I tell them? I tell them, "Even if I fall short, I still will have succeeded." I need to pass this test with flying colors if I want to take the Advanced MECP exam and I will not stop until I get it ... back to the books.

In the meanwhile, you can check out what the MECP is all about. Here is the practice test ... try it for yourself.

Week 4 - Alarms & Relay Theory

Week 4 is just about the hardest week of them all. During the week we learned:

~ The purpose of an alarm system
~ How alarms works
~ Various components that make up a full alarm system
~ Applications of various accessories (i.e. window modules, remote start, remote locks, trunk release, etc.)
~ What relays are and how they work in relationship to alarms and other applications.
~ Why relay are so important in car audio and security systems.
~ How to wire relay(s) to perform tasks

NOTES:

In class we learned that ...

Alarms are only a theft deterrent and is NOT intended to make your your vehicle "un-stealable". A car alarm is designed to drive away a potential thief.

There are many after-market auto security devices, most of them fall under one umbrella. They are as follow (not in its entirety):

D.E.I. - Directed electronic Incorporation are the creators of ...

*Viper, *Python, *Avital, *Automate (Dealership Alarms), *Hornet, *Wasp, *Sidewinder, *Boa (D.I.Y. Alarms), *Rattler *Clifford

Clarion
Alpine
CompuStar
Audiovox

Most alarms consists of 7 components including:
1. Brain
2. Siren
3. Remote (i.e. radio frequency, infrared, magnetic / inductive)
4. Sensors (i.e. shock sensors, sound discriminator, spacial sensors**)
5. Engine Disables (i.e. starter, ignition, fuel disables)
6. Accessories (i.e. window modules, lights, extra sirens, extra sensors, trunk release, door poppers/locks, remote start)
7. Triggers (i.e. spring loaded pin switch, roller push button, magnetic reed switch, metal pressure switch & mercury tilt switch)

**Spacial sensors include infrared sensors, ultrasonic sensors, radio field disturbance and motion sensors.

We covered wiring diagrams for two the CompuStar and the D.E.I. systems including remote start systems.

Many cars today use transponders or resistors embedded in the key as added security to prevent unauthorized starting. Without the transponder or resistor present the car will not start. Chago introduced the class to by-passes and how they work with these transponders and resistors.

Upon learning about by-passes, we learn how they relate to relays. I would say the most impressive thing I learned was how to create a by-pass using relays.

A relay is simply a magnetic switch. I think of it as using a low current circuit to turn on power to a higher current source. Relays operate much like a maze. Relays consist of three parts: terminals, coil and switch.

These are only a few facts that we have learned. I cannot tell you all everything I learn, it will defeat the purpose of becoming an installer. If everyone knew it, what would my job be?

Look it up yourself. OR you can R.T.F.M.!!!

New Email Address - Finally Chosen!!! ... juanromerojr.com@gmail.com

Upon many variations of my name changed all around to fit into an email address, I have decided to use juanromerojr.com@gmail.com as my email address! ... You may sarcastically say "Yeah great job! Do you want a cookie?!" But I say try sending an email to a prospective employer with an email that looked like this:

jr.paperstaxxx@gmail.com

Not that I went out and sent email using this account. I mean it was cool to give out to my friends but what about a first time customer, future supervisor / boss and professional colleagues. Choose your names wisely, it does set a tone.

I feel that my new email is a good marketing tactic as it includes my entire domain and it allows a user to easily remember the email to contact me.

Besides, Google mail is free! I have an account for my friends (jr.paperstaxxx), the new one for business (juanromerojr.com) and one for school at Towson University through their Tiger mail services (jromer1).

Post on MT2 Forum: Student Comments ... My E-Business Reply

So far Mobile Tech is the place to be for a mobile enthusiast in training! I think I have learned more than ever compared to sitting in the college classroom.

The only thing that is pretty rough are the long days taking both mobile electronics and upholstery all in the same day! ... I would suggest when recruiting students whom are also attending another school (college or otherwise) warn them of the time commitment because it is tough not being able to work and make money for the following semester.

I am an e-business major at Towson University in Baltimore and I have done a website evaluation of the website for my Advanced E-Business class. Here are some suggestions that I have for the MT2 website & forum. These are just marketing / usability / navigation suggestions.

Forum: http://www.audiophonics-asd.com/zr/index.php
* This forum is cool.
* Potentially awesome for including new students before they even arrive at the school.
====

* The url could be made easier to remember. Maybe try masking it with:

http://forum.mobiletectraining.com
http://www.mobiletechntraining.com/forum

* Introduce a newsletter (easy distribution and interactive for new students).
* Add a poll of the week.
* Recognize students & past students in the forum (graduates, shop openings, install of the week).
* Include a calendar of events (i.e.: car shows, graduations, special events, open houses etc ...).
* Make a banner download so users can post it in other places (i.e. Myspace, Facebook, Mi Gente, other forums). This can help with online marketing.

Website: http://www.mobiletechtraining.com
* MT2 looks great, it is visually appealing!!!
* Search Engine Optimization is put to use. Good use of Meta tags, keywords, etc...
* Decent ranking in Google & Yahoo searches.
====
* See if sponsors will allow links ... depends on how you want to market the school. (Not a must)
* Update and add some new content because MT2 no longer offers Bolt-On performance.
* Try to Eliminate the use of frames where the banner is (left) and video is (on right). There are 3 frames in your home page. I see the purpose of using the frame, it allows users to view the video while browsing the site, however it forces users with smaller screens to scroll horizontally and you cannot see the entire video ... not good.
* If you would like to keep the video feature try just using one frame with the logo and video in one.
* The video automatically starts, it should either be paused until the users clicks the play or video can play with the volume mute (attenuated).
* There are a few broken links (i.e. MECP Practice Test [Contact Us Page])
* Add a site map. This helps with Search Engine Optimization and helps users find pages easily.
* Page titles should be relevant to the corresponding page. Not every page is "MT2 Mobile Technical Training: New Jersey's ONLY mobile electronic trade school".
* Circular links (links that lead to the same page) should be deleted ... easy enough to do.
* Include a link to the forum either on the home page or in the navigation bar.
* Add a search bar ... some people are link dominant and some people are search dominant.

Check out my website at [url=http://www.juanromerojr.com] JuanRomeroJr.com [/url]. Keep in mind I am not a Computer Graphics Engineer so it is not the prettiest, but it works!!!

I am not dissin', just offering some structured criticism. Feel free to reply!

Week 3 - A Week in the Bay 6/23 - 6/26

The time has finally come when we could put our hands on an actual vehicle!!! The time we had all been waiting for.

To see what I have been doing in the shop, see my photos above in the cellblock.

A day in the bay starts with pushing a couple of school cars out of the shop to make space for the student cars. The school cars are from the junk yard so they don't run. One could assume that this is Mobile Tech's way of keeping us in shape with their 15 minute workout. You have to be limber to work in the tight positions that we are in under those dashboards!

Throughout the week most of the students have been running wires including 0 gauge, installing new head units, amplifiers, speakers and L.E.D. bulbs. There were a few guys installing sound deadening material (i.e. Dynomat) as well.

During the week I had been working on creating my whole wiring scheme laying out of all of my components and running wires in places I never thought I would. The plan is as follows:

* 2 Batteries - one under the hood for the car and second in the trunk separate for audio/video
* Isolator
* Run 0 Gauge Wire
* Install circuit breakers
* Re-wire all of the old components
* Solder all wires possible
* Fix rocker switch panel for lighting
* Capacitor in center console
* Amplifier under the front seat
* Plexi-Glass display with green L.E.D. & Diamond Cut in center console
* 5 band EQ custom install in plexi-glass
* Run power wire for accessories to front console for TV's
* Run speaker wire to doors and rear deck

I have ordered all of my components for Da_Hulk Project, but none of them have come in yet. All I've received so far are the wiring and terminals. I am waiting for 3 pair of speakers, 4-channel amplifier, 2 batteries, isolator, RCA cables, 2 tvs, video amplifier and an equalizer. My products are coming from

* Rockford Fosgate - http://www.rockfordfosgate.com/home/
* Kinetik - http://www.kinetikaudio.com/
* Stinger - http://stingerelectronics.com/
* Farenheit -

Later this summer I will be working on custom kick panels (kick pods), building a custom enclosure, amp racks and a beauty board to display a 10" monitor, amplifier and capacitor. I will also hide the sub-woofer. Custom!!!

I came up with my whole idea for the trunk with a sub-woofer enclosure and everything but it is not in my budget. However, it does not hurt to plan. Hopefully I can finish the trunk later on. I will try to post pictures of what I plan to do.

Week Two - Audio & Video Products 6/16 - 6/19

Now that much of the physical science has been covered, it is time to move onto the components used in mobile entertainment.

During this segment we learned about the following

6/16/08

* Equalizers & Processors

- defined: (a.ka. EQ) a device that will attenuate or strengthen individual frequencies. Used to tailor the sound to your personal taste.

- defined: the processor makes a matrix, changing the signal to create simulated effects

- features: # of bands, low-level RCA inputs, high-level inputs, multiple inputs, voltage output (more voltage = greater sound quality and loudness), handles up to 16 V (~ac), digital or analog

* Amplifiers

- defined: a device that strengthens the amplitude of an input signal offering minor tuning & makes the biggest improvement in sound.

- features: a# of channels, power (watts), inputs (high & low level), R.M.S. (root mean squared), output, Daisy Chain, subsonic filter, high-pass filter, low-pass filter, fans, colling systems, heat sink, impedance level, sound to noise ratio, total harmonic distortion, MOSFET, gain.

- Classes of Amplifiers:
A - Sound quality
B - Loud Sound
A/B - Hybrid of A & B
D - Lots of Power

4 Stages of an Amplifier:
1. Power Supply - +12V, ground, remote input, transformer, capacitors
2. Input Supply - Audio signal (high / low), crossover settings
3. Driver Stage - (amplification) uses a series of resistors and transistors to increase the signal from the previous stage. (potentiometer / gain, M.O.S.F.E.T.)
4. Output Stage - channels for speaker connection

* Crossovers
- Types: Passive vs. Active

- defined: Passive crossover is a device that separates the frequency spectrum to dedicated drivers and is place on the high-level side following the amplifier.

- defined: Active crossover is a device that separates the frequency spectrum to dedicated amplifiers and is placed one the low-level side before the amplifier

- features - resistors, capacitors (bass blockers), inductors (coils)

* Speakers
- defined: take electrical energy and converts it into mechanical energy, thus producing acoustic energy

- 11 Parts: terminals, tensile leads, voice coil, former, magnet, cone, spider, surround, frame, vent pole, dust cap

- features: type, size, frequency response, power, mounting depth, diameter, enclosure, sensitivity

* Sound (More Science) -
- defined: vibrations moving through air creating pressure and moves at 1130 ft/sec

- Parts of Sound:
1. frequency (Hz) - # of complete cycles
2. amplitude (A) - strength of a signal
3. period (sec) - time
4. wavelength (ft) - how far sound travels

* Mobile Video - LCD vs. CRT
LCD - Liquid Crystal Display
CRT - Cathode Ray Tube

RCA Jacks
Composite cables
S-Video
Component
HDMI - High Definition Multimedia Interface

* FM Transmitter
- defined: a device used to send a signal over a FM station
- types: wired & wireless

* Audio / Video Switches

* O.E.M.

Other topics were covered in class including how to use a Digital Multimeter (D.M.M.) to set volume & gain control to reduce distortion, wiring location programs and online community for Pioneer at M.E.L. (Mobile Electronics Live).

If you have any questions about how classes are at Mobile Technical Training just send me a comment below.

Education is key and you will never get away from science, because knowledge is power!

Week 1 - The Introduction to Mobile Electronics @ Mobile Tech (MT2)

It has been two weeks already and I have learned a great deal of new information. I even got a second chance at re-learning some physics, needless to say our instructor (Chago) makes learning circuitry and the properties of electricity much more interesting than my 12th grade Advanced Placement Physics teacher (Mr. Lane - Suitland H.S.).

Week One:

Day 1 - The first official day of class was a lot of introductory information. We discussed:

*Introduction to Mobile Electronics
*What it takes to become a Mobile Electronic Certification Professional and its different levels
* MECP test is composed of THREE parts. Part 1: Definitions & Math (50 questions). Part 2: Shop Safety and Tools (50 questions). Part 3: Navigation, Products, and installation (50 questions).
*M.E.R.A. - (Mobile Electronic Retail Association)
*C.E.A.- (Consumer Electronic Association)
*Scott Owens - recent world record for SPL (sound pressure level) @ 180.3 dB (sponsored by Pioneer)
*Steve Brown & Chris Yato - amazing installer team representing Alpine
*Mark Fakuta - the true creator of Rockford Fostgate
*I.A.S.C.A. -
*S.P.L. - Sound Pressure Level, measured in decibels and symbolized by dB.
*R.T.A. - Real Time Analyzer, measures the amplitude of of individual frequencies. Used to tune the vehicle for optimum sound quality.
*Tools an installer needs:
- Yes, I went out to get everything I did not have in the first three lists. Not to mention a good toolbox!!!

There are SIX tools that emerged because of car audio
1. Torx Keys, 2. Hole Saw Bits, 3. Panel Poppers, 4. Door Window Hand Crank Spring Clip Removal Tool (Yes that is what is called!), 5. Step / Uni-bit, 6. Wheel key

Other tools an installer must have:
Allen bits / keys, Awl & Picks. Calculator, Digital Multi-Meter (DMM), Drop Light, Electrical Tape (#33+ - 3M is the BEST), Open-ended wrenches or ratchet wrenches, Ratchet & Socket Set (Metric & Socket), Screw-Drivers (Full Set), Screw Gun / Drill, Soldering Iron, Rosin Flux Solder, Tape Measure, Volt-Ohm Meter (VOM), Wire Cutter / Stripper / Crimper,

Miscellaneous Tools:
Aviation Snips (aka Metal Sheers), Dremel, Drill bits, Electrical Connection Kit, Goggles, Hack Saw, Heat Gun, Hot Glue Gun, Level, Markers, Pens and Pencils, Mechanic Mirror and Magnet, Palm Sander, Power Nibbler, Right Angle Drill, Set of Pliers, Utility Knife / X-Acto Knives, Vacuum (Wet/Dry), Wire Ties

Shop Equipment:
Air Compressor, Battery Charger, Computer w/ Programming (i.e. Customer Data, Vehicle Info, Enclosure Design, etc...), Drill Press, Fabric Sheers, Jigsaw, Noise Sniffer, Portable Florescent Lighting, Good Camera (Catch your work), Real Time Analyzer (Need For Tuning), Signal Generator, Table Saw, Ventilated Fabrication Booth (Paint / Wood Shop), Welding Torch, Work Bench

*Shop safety.
*O.S.H.A. - Occupational Safety and Health Administration
*M.S.D.S. - Material Safety Data Sheet
*Class D: Halon extinguishers
*Magnuson-Moss Warranty Act - warranty void only if upgrade or modification is direct source of the problem! An alarm system should not void warranty. "Wouldn't you want to protect your brand new car?" ... Think about it! What does a right tire falling off after the installation of an aftermarket alarm system?"
*Humans hear frequencies between 20 hertz and 20,000 hertz (and that is perfect hearing!)

I would have to say the most important thing that I learned from day one was, in order to increase the amount of decibels (dB) by 3 you have to double (2x) the amount of power (watts). Word for all those that like loud music ... 100 dbs for 2 hours can begin to cause damage to hearing.

In upholstery we went over the parts of a sewing machine, tools for the upholster, the different types of fabrics and materials needed for a project and shop safety. It was the only class period when we have to take notes, everything is hands on besides written tests.

Day 2: No hands-on stuff until week three ... DANG!!! I was ready to get in the installation bay but not before the basics. Just when you think you know it all!!!

In class we went over:
*Basic Symbols of Circuitry
*Ohm's Law

E/I*R and P=I*R

E = Voltage (Volts) "aka Electrical Motive Force (V or mV)"
I = Current (Amps)
R = Resistance (Ohms)
P = Power (Watts)

*12V Car Battery Basics
The battery is used to start the car, power the car when the engine is not running, smooth out spike, surges and ripples and help the alternator while running. Brand new, the battery should put out 12.6V and while running the battery should put out 13.8 V. While off the car should pull
*Alternator
Creates a magnetic field generating electrical power from mechanical energy form the car's engine. This is also where rectification of AC to DC using Germanium Diodes and where the power is supplied for charging the battery.
*Diode - (Allow +)/ Cathode (Restrict +)
*Capacitors
*Parallel vs. Series Circuits

In upholstery we started hands on right away learning how to properly thread the machines, sew a seam, lock stitch, sewing boarders, double stitching and tuffling. It was really hard jumping in the first day, but it has progressively become easier with practice with the machine, especially when it comes to the variable speeds of the machines!

Day 3: We had our first quiz covering shop safety and tools, which I passed with 100%. For the rest of the day we worked on circuits and doing math and started looking at the basics of an audio system starting with the Head Unit.

We learned:
*How to make a system louder
*How to supply enough power without killing the battery & altenator
*Application of Ohm's Law
*Transistors (Bad boys rape our young girl, but violet goes willingly!)

0 = Black, 1 = Brown, 2 = Red, 3 = Orange, 4 = Yellow, 5 = Green, 6 = Blue, 7 = Violet, 8 = Gray, 9 = White
[Value 1&2 , Multiplier 3, and Tolerance 4 (Gold 5% / Silver 10%)]

*Head Units

Power
Yellow - +12V constant (In)
Red - Accessory +12V (IN)
Blue - Power Antenna (OUT)
Blue/White - Remote (OUT)
Black - Ground (IN)
Orange - Dimmer (IN)

Audio
White - Front Left Grey - Front Right
Green - Rear Left Purple - Rear Right

That day I learned that I was hustled by some shops in the way they hooked up my system. I also figured that I took half of the correct steps to correct those installs prior to attending MT2. ... Oh yeah, we also got homework mostly covering Ohm's law.

Day 4: We covered the rest of Ohm's Law and for the last hour we covered half of the stuff on head units including what to look for in a head unit and its job as a component in a system.

The coolest thing that I learned from the lecture was that you don't need a head unit to have a system in your car.

In upholstery we continued to practice our pieces using square sheets of vynil fabric. Upholstery is mainly hands on. You either get it or you push your way through. see my pictures just below the title at the head of this blog.

Closing the week off:

For the weekend I went home to see my girlfriend and meet her family at their family reunion. The ride was long and for all that gas I could have went by air! ... It was nice to get out a little though. We are in class from 9am to 5pm with electronics and 6am-9:30pm for upholstery, just imagine! That is just week ONE! There is a test on Tuesday of week Two covering everything form the first 5 day, mostly Ohm's law and the MECP practice book material. Time to read ...

Orientation - Day 0 (June 6, 2008)

What’s up everyone! Hopefully you all are fine and in tuned for another day of learning on this earth!!!

The Trip (Towson, MD to South Hackensack, New Jersey)

Well, I made the trip up to South Hackensack, New Jersey on Friday June 6th it was 191 miles and quite the ride. Pulling a trailer with tools, personal belonging and DJ equipment was a 3-hour drive at $4.07 for gas in Maryland and $3.89 in New Jersey. At least gas is cheaper here (knock on wood). It cost me a total of roughly $75 in gas, not including the 3-4 tolls that I came across. Not to mention it was kind of hot considering that I have leather seats and NO A/C, you can only imagine!

I am staying in North Bergen 15 minutes from Mobile Technical Training in a predominately Latino community, which is pretty cool. The atmosphere is pretty nice and the music is amazing ... I love it!!!

Orientation Overview

When I arrived it was orientation time. I was excited and extremely tired from the commute. In the classroom there were approximately 15 students. There we meet two of our instructors Chago and Ray and watched the Shattering Subwoofer (Episode 58) from the 4th season of Myth Busters. The video clip was followed by introductions of all the students and a discussion of the Shattering Subwoofer video. Next, we went over the syllabus for the course along with the rules and regulations for our 10-week attendance and other miscellaneous items that we need to know including what tools we need for the course, cost of materials, what is covered by lab fees (basically what is free for us to use) and discounts available to us as students of MT2.

Episode 58: Shattering Subwoofer from Myth Busters (Season 4) ... Full episode available on iTunes

Chago then went of the content of the course, which will consist of the itinerary mentioned in my previous blog entitled “Mobile Technical Training Summer 2008 Syllabus” (6/3/08). We were also notified that we have a paper to write, which must be two pages minimum and range within the topic of mobile electronics. Of course you already know what I am all about … APPLE INC baby! I have decided to write my paper on iPod car integration, with a focus on the following:

• Brief history on iPod and Apple Inc.
• What is iPod integration?
• The goal of integration?
• Why it is important to us?
• Who is participating in this sector of mobile electronics?
• Aftermarket vs. Auto Manufacturers (OEM)
• What features are available?
• How popular is the technology?
• Who is on top in the industry?
• Pros and cons of the technology.

Mobile Technical Training (MT2) Intro Video

Diverse Classmates

Meeting my classmates was interesting because I thought that the class would be primarily of students out of high school living in the area. Let me tell you how wrong I was!!! First of all people in my class come from West Virginia, Pennsylvania, Illinois, Maryland, and of course there were some local New Jersey representatives (more out of state than in-state). It was also interesting to find that there were also other college students attending the course, which was very pleasing to know. Most surprisingly there were also a few partnerships already established in the room. Some of the guys enrolled together with intentions to earn their MECP certification and later opening their own business. That is cool … WHY THE HECK DIDN’T IT THINK OF THAT!!! Maybe I could have found a roommate and a cheaper place to live! $800 a month … in an apartment!

MT2 Staff

The staff here at Mobile Tech, so far, has been very welcoming and helpful and might I say very patient. This is a quick little summary of the staff in the order of their appearance (when I met them):

Andy Herreros was the first guy I met. He is the Admissions Representative for the school and was my contact person, I am guessing because I have pretty much spoke with just about everyone in student affairs. I meet him the Summer of 2007, where he took me on a tour of the facility and showed me one of the schools show cars along with Ramon. It was a 2007 Dodge Charger with the works, I don’t know the specifications but it is very nice.

Danny Bonanno is a School Representative, who seems to be a pretty up-tempo and motivated guy. I will be talking to this guy frequently because he is in charge of the Job Placement program. That’s the whole reason I came here … to get hired in a GOOD shop and of course the learning experience!

Karina Marroquin, Administrative Director and Student Affairs, has been helping me to get everything together financially with all of this loan information. I hope she gets paid enough to deal with all those phone calls and faxes that I have been sending back and forth!!! I really like here because she is very patient, nice person and seems to like her job.

Chago Betes, our instructor for mobile electronics is really chill and laid back, very informative and is very knowledgeable of the topics introduced. He even showed us a speaker that he constructed from scratch made of cardboard, tape and a little wire. I thought that was pretty cool.

- "You can't know everything. Will teach you atleast one thing!" - Chago B.

I learned several things: (1) Tools, books and materials are expensive, (2) you can make a speaker out of anything, maybe not a pretty one and (3) trade school has just as much structure as a college course.

Ray Olvera is another instructor we have for mobile electronics. I have not seen this guy in action, but from what I hear he knows his stuff. He’s laid back and has the many, many years of experience a guru if you will. Apparently he knows a thing or two about website building. I think I will be learning a lot from this guy in both of my fields!

Ramon Gallegos assistant instructor briefly meet him.

Gene Olvera is the school’s Director. I have yet to meet him, all I know is that he is cool with the police chief of S. Hackensack and that he has seen this blog after I sent him an email. I guess that is cool … Hopefully I can meet the boss on Monday (our first official day of class).

Ben Paise is our upholstery instructor and I have yet to meet him, but I will definitely be talking to him a lot about working on and touching up the interior. I am drawing up the plans now.



SHOUTOUTS:

I am here now living out just one of my dreams and I am just glad that there are people out there supporting my dream. I would like to say thanks to:

Edna & Juan Romero Sr. (Mom & Dad) – gave birth to me and at looking our for me incase I fall ... but I am going to try to make it out here by myself even though I am broke! I know my family is there to help me stay on top of my dreams and I will never let you down!

Lynnette Tellis (Aunt) – helped me to get my first car and hooked me up on several occasions. I cannot list the many things I have learned form this magnificent woman! And she let me crash at her crib for a while until school started (something I have always wanted to do).

Craig Hickerson (Uncle) - motivator for higher education and supporting from Washington (the state).

Mary Sydnor (Girlfriend) – my motivation and motivator and ever so beautiful girlfriend. She motivates me to push the envelope and had been helping me to better myself spiritually and as a person. I love you!

John & Jonathan (Brothers) – my blood, always interested in what I am doing … here is something to follow. You can make anything happen …just look here! I am here for you guys just hit me up anytime.

Engin Toper & Will Lugo (Lambda Theta Phi Brothers) – I have crashed at these guys houses more times than you can imagine and if it were not for them I would have had no idea as to how to get to NJ because I never drive when it comes time to drive up for out fraternity meetings. It’s all goo though!

Ruth Calle (Lambda Theta Alpha Sister) – hooked me up on the clutch. Late in the game I went out looking for housing and she let me sub-lease her room in her apartment. Thanks Ruth.
