Here is what I am working on

Headunit and Options
Alpine CDA 7894 (AMAZING SQ and Options) also the green matches the 03's factory lighting. 3 -4V preouts


KCA 420 for Iphone's and Ipods



For the Box
Start of the design.


Here's when I finished the frame and internals of the two 10" type R's box

Notice the down firing spec. By going that route I had about 5.875 top mounting depth.

Also note how I countersinked them about 1/4 ito the MDF to help with some depth

 

I used an old Type R I blew as a guide to go by. Also helped out with making the proper baffle

Heres the double baffle which will serve as a mounting place for the legs to lift the box to give room for excursion of about 20mm.

Heres the ("legs") on top of the baffle to give room for the Xmax

With carpet on it fitting into the back seat slots.

Legs holding it up to breathe and not hit the floor

Notice how flush it is to the rear seat(11.25inches)


Next I upgrades the "big 3" with 1ga mining wire. Then ran the same wire to my dist block for the amps.


Now for the back seat amp rack since I got these in:

Notice the two brackets holding the back seat to the cabin. I had to refab this part to make room for the amp rack. Heres a shot of what I am talking about

 

After tons and tons of measurements I decided to try to fit my two Rockford Amps behind the seat. Please not these amps are only 2.25" tall and not many amps are compatible for this installation. (especially ones with bad heat sink designs)

I looked over my truck a 100% times for good placement of these and the only two locations I found were under the seats(front) or behind the rear back rest. For the true hide-a-way look I decided to use the behind the rear back rest location. The amps I used for the install are Rockford Fosgate Power Series T600, and T1500.

Here are some issues you will have to over come. The first is the slide mounting bracket for holding the seat back.

Their are two of these, one on each side of the truck. Approx ~34inches apart. So I knew my two amplifiers dimensions 15in and 13in. and saw I could manage to squeeze them in.

The next problem was all the steel wire caging that supported the seat /foam.

Since the amps will be fitting in between the mounting brackets, all I needed to do was clear out some of the steel caging from the middle and resupport the mounting bracket piece for a safe solid reinstall. So I pulled out the dremel/recip saw and a welder for the next step.


This is the piece i cut out.



BEFORE WELDING TAKE THE FOAM OFF THE STEEL AND PUT SOMETHIGN THAT WONT BURN UNDER IT!!
I used a mig welder and some .5inch strips of steel. See pics for placement(you want the supports as close to the mounting brackets as possible to give room for the amps).





With all this done we have the following space. width-34in, depth ~11-12in, width- ~3in.

 

Now to the welding and bracing part for the back seat frame.
Obviously this requires a welder, heres the one I used.


I had to cut some of the old framing for the back seat off to make room for two 15inch wide amps. Once I cut the excess of I re-welded some steel rods for support(two places where the back seat is held to the cab)



Once I made room it was time to fab the MDF amp itself.
Here is a few shots of the amps being couternsinked into the MDF to leave room for the seats





I also used the amp rack to hold some bolts for a distribution block. I hate paying crazy amounts for stupid fuse blocks and dblocks when you can make one this simple. I used a copper bar on the rear countersinked(covered with plexiglass) to attach a 250, and 100 amp fuses. This was all done with 1ga mining wire.

 

Heres a few shots with the amps in place





I didnt have much room to work with

Made a built in slot to hold relays, and fuses for; Fans, Heatsink Fans, and a better Remote signal(this has a sliding place for a piece of plexiglass)

More relays and switches hid to run 30amp for lights and 4" Vent fans.

I used L brackets to mount it to the stabilizing bar for the cab

 

Final touches





ENJOY and Comments/Suggestions are welcomed.

 

And had to show my newest upgrade... haha tinted lights

 

Very nice work. I wish I had your skills and patience.

 

Haha when you are a teacher, you have lots of free time in the summer. I uploaded a couple of my how-to's I did over summer on here. Feel free to check out the others

Gun Rack Build
Starter Upgrade
Extra Battery
Full Audio
And Temp/Compass Fix

 

Looks good. Did something similar with my single 10" type S. Need to carpet it still.

 

Looks good, I use to have the same amp MRP 500 mono in my old car.
