The Forester hatch has a few hidden compartments build in using foam. They waste a lot of space so the potential to replace the foam with an amp rack is there. I'm going to replace the Left side panel, its long and wide enough for a 200.4 to just fit and all the wires to clear. Here's where its going to get tricky, the center panel that covers the spare tire rests on a portion of the left panel. The amp rack will have top plate which I'll cover in carpet so it all looks OEM to the casual observer and I'll be able to use the hatch area to stow gear.
I'll be throwing all sorts of stuff in the hatch so the amp rack will have to support the weight. Probably the heaviest thing will be the race tires, about 150lbs distributed over the entire hatch area with seats down. My biggest problem will be supporting the top cover, with the 200.4 in place it takes up most of the room so I'm not sure if/how to support weight and build stand-offs. That's where I'll count on you guys for the experience and ideas. I want to keep it simple and as lightweight as possible, no fiberglass or bondo.
This is the left panel I'll be replacing with an amp rack. You can see the bare foam on the right hand side on which the center spare tire lid rests.

The base of the amp rack cut out. I used 1/2 inch plywood and I plan on using the same for the lid. With proper supports I should be able to lean on this and store gear without cracking it. I'll screw it down into the metal to keep it from moving.

Various shots of the 200.4 to give you an idea of what space I have left to build stand-offs/supports

Rear bumper side

This is the side right up against the rear seats. There's just enough room to run the speaker wires out and to the side.

Left side against seats

This shot gives you an idea of how much clearance I'll have between the amp and the top rack. The amp is under the plastic, that ribbed thing is the spare tire. Its not much space but with the fans I don't see overheating an issue. I have a simular install with a ZX450 in my wife's car and it never overheats.

So how would you go about supporting the weight and install the top rack ? I'm planning on screwing it down to keep it in place.
I took a little descriptive video of the whole deal to give another perspective. I have the ZX450 so I don't have to run a Xenon 200.4 but it would be nice. Let me know if its possible, suggest away.
