6.Darren removed the box and covered the back of the cab with some extra loop carpet I bought from ACC to match the carpet kit in the truck. Then, the box was set back in place and the location for the amp was determined. Behind the driver seat worked out to be the best. The amp was screwed directly to the back of the cab, so yes there are four small screws visible between the bed and cab. Darren was going to bond some wood to the cab and then screw the amp to that to prevent the screw issue. I told him I don't give a rat's ass about the screws showing, so just go for it.
