I'm looking to mount an amp in a back side wall.....its so close to the outer sheet metal that everything inside is slightly contoured. I want to put something like 1/2" plywood, etc as a base to screw the amp down (as it will actually be sitting vertically on the wall). The inner panel is straight up and down.

My "guess" was to maybe use Great Neck foam, etc. to make a sticky base that would mold itself to the contoured inner wall, then put the wood into that.

Does that sound feasible? Any suggestions?

T-88 or Scotch-Weld. Both are available from aircraft homebuilders supply houses, like Greap Plains or Aircraft Spruce and Specialty. You'll need to grind the metal a little bit to expose bare steel and give it some tooth, and immediately glue in what you want in. I;d strongly recommend giving the ply a coat of resin and paint, since anything that close to the outside of the car is effectively outside, and should be treated as such. You'll also want to hit the glue joints with some primer after they cure to cover up any exposde bare steel.

I've used JB Weld to accomplish what you're talking about. First wipe down the metal with acetone to remove the factory paint in that area. Then bond your board to it with JB Weld and hold it in place. JB Kwik works faster.

I was thinking about JB weld.....would take ALOT of it though.

There is some inner framework within range that I was considering using metal straps - like they use on large ductwork - and suspend it like that. Its a JL300/4 so it isn't a HUGE amp.

Thanks all.
