    Amp Mounting to Rear Shelf/Floor

    I want to bolt mine down to the sheet metal behind the rear seat. What I wonder is what length bolt? It appears the fuel tank is right below this spot.
    Any suggestions would be appreciated. Thanks.....

    Fuel tank is right behind there, so be careful. I would suggest going higher (the brackets for the rack) and farther left and right. Look for reference points (i.e. bolts, wires, etc.) and see if you can see them from the other side, checking for clearance. Self tappers? or bolts?

    You could spot weld it into place...

    I was thinking self-tappers. I suppose maybe I could get some metal plates
    and just put them under the carpet to clamp it per say to the carpet.

    Unless there some seriously large plates,I don't think it will going to hold up well. I've tried that other vehicles in the trunk walls and it slaps/bangs around. I would only do that if the amp is: a) small in size/weight and b) laying flat.

    I haven't checked out clearance between the tank and sheet metal that makes up the rear area, but if you drill a really small hole through it, you can use the drill bit as a "depth finder" (as long as you know there is some sort of gap). Pushing the drill bit through the hole by hand after the hole is drilled to see if it hits anything. I'd then mark the drill bit with tape or something and use that as a guide to find the correct length self-tappers. And you now have a pre-drilled hole as well for the screw so it isn't a pain to get it started. Also keep in mind that too thin of a self tapper isn't going to hold up a huge (weight) amp.

    I would make sure that there is some sort of gap though, using mirror or what have you to get up in there. I had a friend who drilled through it all in his 98 cavalier b/c the tank was butted up against the seats.

    Here is a link with the floor cut out to replace the fuel pump. Maybe you can use this to judge how long you can go. http://www.worldisround.com/articles/12533/photo13.html

    Thanks Bigron
    That pic is very helpful. Looks there there is not a ton of room. Makes me wonder how many people have driven a bolt into their tank.

    just slide a piece of plywood or something underneath the carpet, then you can have something to safely mount the amp to and not have to worry about it moving around.

    I mounted my amps there. I put a piece of wood under the carpet and used self-tapping screws to mount that....I then mounted my 3 amps to the wood with screws once I put the carpet back over it. No problems and had it that way about 8 years. That was in my 96 Camaro.
