Haha I saw someone remove the seat and put a board there then the amps, and that went right on the metal, another one i saw someone use 3m tape to secure the amp right to the metal back wall...
is that even safe? haha
And from what I remember there is no plastic between the window and the back seat, not enough room, there is some type of fabric material and the child seat straps i believe.
So right now the plan would be to use as much of the old amp rack as possible behind the seat, then put the sub in front, and run the wires either under the carpet (should I be worried about wear and tear there?) or run them the long way down the side of the truck under the plastic trim/floor panel.
