I'm thinking of putting in a false floor to replace that stupid carpeting that came with the car. I've seen a few topics on several forums that people have done it in 4 different parts: back of trunk, over spare tire, and sides. Would this probably be the best way to do it? Has anyone done it? I'm not going to be mounting amps inside the wood or anything (subs are back, amps will be between box & back seat).
