Introducing our box for the new GM Double Cab. Even though GM's new style double cab is a bit more restrictive under the rear seat than the previous model, we still managed to create a nice looking, super nice fitting downfire box that will hold two 10s or two 8L7s. This box will fit both seat styles--the full bench, and the new 60/40 split seat like ours is equipped with.
