custom side panels > sub and amp mount?

[Super Chevy]

i planned on removing the cork-board side panels in the rear of my 87' k5. I wanted to make some custom side's with some 1/2 plywood and have my 6x9's,also make extensions in the back to allow 1.5 cubic feet per side for my 12" subs,then on the pass. side behind were i want to put the ashtry back in the original spot a square recess for my amp,then tuck in my wires ( 4guage and monster cable av ). will 1/2 work? also whats nes. to mount the shoulder belts and ashtry's? I wanted to do this to help with theft protection and give me more room over my Q-logic hatchback. I wanted to cover it with grey fabric ( dont know what is would be a good material? ).

sorry to rant on,but this has been on my mind latly,cant get any thing though my mind in school except the k5 /forums/images/graemlins/k5.gif /forums/images/graemlins/deal.gif

Use 3/4 in MDF and make sure you paint it with fiberglass resin if you ever plan on getting water in there.

You will only need one sheet. I did my '83 K5, 3/4" for under 30 dollars for wood and carpet

You have metal braces back there along with screws into the lip where the top bolts down. I think it will be strong enough.
