Sub Wall in a coupe Options

[Legit94GT]

So i have decided to remove my box in my trunk and to mount the subs into a wall in my trunk. I say trunk because i have coupe. So i understand how to make the wall and mount it to my car the fiberglass it too the sides of my trunk to keep it in place and looking good with out rattling around. Now if i make this wall the only thing that would act as the back(like the back wall in a box) would be my back seat.

So if i mount my subs into a wall in my trunk can i use my seats as the back of the "box"? or will i need to make a back pannel?


I say "box" beacause i will be using my car's body to make up the top bottom and sides of the box... if it is unclear what i mean please let me know and i will try to explain better...

Bump...

I want my subs facing the rear of the car, i want them to go into a wall that then uses the trunk as my "box" i would put another peice behind the back seats to give it a good "seal" i'd have all the sheet metal dyno matted. Thus i am using that space below the rear deck lid as my box...

My dad is concerned that if i do that i will end up weakening and exposing the weld on the frame that holds the top on to the body, and that then it would show through the paint and be unsafe... ???

Any thoughts or opinions would be greatly appreciated...
