Just wondering where all of you who have amps installed them. Im thinking the back wall behind the rear bench but i dont want to screw right through the back wall and create some holes for rust to start growing, any pics and suggestions?

Also wondering on sub box that would fit under the rear bench seat anybody make or buy something to fit these trucks? Mine is the extened cab
