Custom Sub box and Amp rack installed

well since my car is drivable again I needed some tunes, so I put my old audio system back in. I have a single 10" Rockford Fosgate (4 ohm) shallow "Punch" sub with matching amp, 600 watts max, 300 watts RMS, Kenwood amp for the speakers thats rated at like 60 watts RMP per speaking I think, matching Kenwood 6x9's and 5.25's, and a pioneer head unit with Ipod hook up and a remote.

Here's the old box I had, and the amps that I had to fit in the rear well:

I decided to mount the sub to the side like in the above pic, have the rockford fosgate amp recessed but still in view, and hide the kenwood amp under the cover board. Here's the rough cut cover board:

I thenk used some scrap to mount the amps, and painted the back drop black to hide it:

test fit the amp:

then I built a small box (0.5 ft^2 as per the sub requirements), and its not in the pic but the Kenwood amp is mounted on the bottom of the amp holder

then I wired it all up, tucked the wires, and here it is:

from the outside:

Now I just need to get some matching carpet, and a head unit to chassis adapter, plug it in and crank up the tunes!

Re: Custom Sub box and Amp rack installed

it looks real nice. i just put a custom sub in my vert. it takes up the whole trunk not just the well though. i have 2 12s and my amps are under the lid no room to show them. the stereo store has the carpet. i'd post pictures but i don't know how if you could tell me your pictures are awsom.

Re: Custom Sub box and Amp rack installed

finally got the head unit in and all wired up, 100% soldered and heat shrunk no crappy crimp connectors or wire nuts in my car It sounds really good with the sealed box, I forgot how good these cars were for bass, it's LOUDDDD with the hatch closed

still waiting on carpet, I have it picked out from 1A-Auto I just need to order it (and a headliner, hatch struts, and speaker covers)

Very Nice! How does it sound? Does it rattle the spoiler much?

Re: Custom Sub box and Amp rack installed

I have no idea hte dimensions of the box, sorry :/ I just measured wit ha tape measure and cut the boards out - it was real easy

It sounds really good! I like a sealed box its much tighter sounding than the old ported box i had 2 setups ago. The only thing that rattles is the liscense plate and my head!

Thanks for sharing. I had an idea like this in my head, but it helps to see it in real/picture life.

Re: Custom Sub box and Amp rack installed

Setup looks great! How does the box stay seated in one spot? Is it sat on the lowest spot of the box where the sub is mounted?

Re: Custom Sub box and Amp rack installed

yeahthe bottom of the box rest on the floor of the trunk well to support the board. I had a problem with it sagging becasue it wasnt quite touching, so i made some spacers (blocks of wood) and now its all good and supported

Re: Custom Sub box and Amp rack installed

Great job, looks similar to the one I had custom built to the specs of my sub. It sits low enough in the well that you can make a protective carpeted cover flush with the floor.

This is made from expanded metal (basically a strong screen) re-enforced with a framework of 1" stock and covered with carpet to match.

I left those out because I didn't want to hijack the thread. I started a thread on the build 5 years ago, I've seen it resurface a few times. Search under my name for "sub box and amp build."
