I'm going to lay in a sheet of 3/4 plywood in the bed area. Then screw it down to the body. Then lay the carpet over it. Then I can screw the amp rack down. I will also remove the sub speaker, then screw the sub box down with half a dozen screws to the board. Then reinstall the speaker. If anyone wants to steal this one it isnt going to be easy. And it will keep everything from becoming a projectile in case of an accident.
