I had a 2.2cubes sealed box under my extended cab 07 classic subthump has the biggest prefab I could find I decent quality though they don't have an 8inch box for that truck
Anton Miller of TML or Pure Pressure Concepts is going to build me a box or two separate boxes.. He doesnt have access to one of these body styles, he said his dad has a crew cab duramax but im not sure of the rear seat is is the same? He also didnt say what year it is but im assumin its a NBS
Im throwing around the idea of a single 10 now as well.. maybe build the box under the rear seat behind the drivers side and have the sub stick out facing foward or have the box sit behind the drivers side seat and have the sub face up? I got 1000 watts to play and want some SQ but also looking for wow factor..
