Hello all, this is my first post and I have only had my H3 for about a month now. Its my first Hummer and I love it! I have been in car audio professionally for 7 years and have only recently moved on to a different form of business. So this will be my first full build since I have left the business, here we go! (pictures to follow soon)

2006 Hummer H3 full SQ system...

-Excessive Amperage High Output Alternator
-Kinetic HC1800 battery
-Kinetic HC600 battery
-(2) 39 square ft. bulk packs of Hush Mat
-Alpine INA-W910 head unit
-Alpine PXA-H701 processor
-Audison LRx 2.4 2 channel amplifier
-Audison LRx 2.9 2 channel amplifier
-Audison LRx 1.2K mono block amplifier
-Hertz Mille MLK 2 6.5" component speakers
-(4) Hertz HX 300 12" subwoofers

I will be bi-amping the MLK 2's with the LRx 2.9 and 2.4amps, and the 4 HX 300's will be in a 7.12 gross cubic ft box tuned to 38 HZ.

 

I have a few pics of the starting progression, but its still in the very early stages..





Test fit


Holes cut for subs and ports


Ports installed, routtered over edges, and did some bondo smoothing






Still a ton of work to be done. Will update as I go. What do you think so far?

 

Laid out the amps and crossovers to see what it will all look like before i build the rack mounts. Aren't those crossovers gorgeous?

 

Very nice man. What's the specs on the alternator? I've been needing one for my build. Pics would be cool too =]

 

I have had not so go luck with EE, personally I would look into Mechman, Powermaster/XS Power or even Ohio Gen. Just my 2 cents

 

Build looks great. Audison/Hertz/Conection make great products. Port area seems a bit small but then again, I spent my years mostly around DB Drags Bass Race & IASCA Bass Boxing. I would have expected it to be tuned slightly lower also for SQ. Look forward to seeing the finished results. I got a bunch of stuff I want to do with the H3 (audio wise) but I have took a little break from CA and been into trail riding and off roading lately. Once the H3 gets built up, I will start on the sound system. Unfortunately with all the gear in my H3, there won't be enough room for what I am used to.

 

Hope you don't find this as thread jack but I thought I would share (if it is, let me know and I will remove it). Here is a box I built for my blazer right before I sold it. Box was built for daily driving and ocassional bass racing.

3/4" 13PLY Birch
Double Layer Baffle w/ Second Layer Flush Cut
1 1/2" Birch Dowel For Bracing
6ft^3 @ 35Hz After All Displacement

Done

 

Few more pics, unfortunately the build never got completely finished before the vehicle was sold.

Got Power? XS POWER


Amps! Sundown Audio SAZ-4500D & Three SAX-125.2's for mids & highs



Someone say mids & highs! Pro Audio 10" B&C 10NW64's & Selenium D2500Ti-Nd Drivers (same drive as the Image Dynamics CD Ultra) w/ Image Dynamic Mini Bodies





The fiberglass door panels that never got used, still sitting in my garage



Processor - Behinger Pro Audio DCX2496 w/ DSPower 12V Power Supply Mod

 

TURN THAT **** DOWN...Damn I suddenly feel old

 

I will say I'm not entirely happy with the stock stereo in the H3/H3t. Worst reception of any car stereo I've ever had, I thought there was maybe a bad antenna connection on my H3, but my H3t is the same. However, with a good clear station the stock H3 Monsoon stereo was great to me. As loud, clear, and thumping as I'd ever want. The T is a bit lacking in the bass due to no subwoofer. I'd consider an upgraded head unit for more features such as mp3 or blue tooth, and I'd like to get a small subwoofer installed in the T.

I'll give you props for what appears to be the start of a nice quality job, but filling the back with a huge speaker box just seems like useless overkill and a waste of space. If that's what you're into, go for it and enjoy. Maybe I'm getting too old, but I just don't get it.
