Thoughts on this.. Thinking about pulling the rear seat out of my 08 F250 Crewcab and come up with a box design that will mimic the back seat portion that you sit on.. Thinking maybe running either 2 10's or 2 12's but not sure what style of box for them.. Do you think this would be a capable idea of making bracket to mount on the box to have the back piece added and install the seat cushions with no frame on the box? subs hidden to keep them safe from feet and say the port on the middle??
