2001-2006 GMC Sierra Crew Cab Sub Box HD

­GMC for some reason felt the need to change the rear seat arangment on their 01-07 GMC Sierra HD trucks and made them different than their half-ton brothers. There is a little more room under the seat, not much, but even less behind the seat now. A small box can be made to hold a couple of 8” or 10” subs and will go behind the rear seat. In order to get this box to fit without damaging the subs the fold down tray that covers the gap between the rear seat and the back wall needs to be unbolted. The folding part that sits on the back of the back seat can hit and limit sub movement.

This box is 1.26cuft of total airspace and will fit 8″ or 10″ subs up to 5″ deep, or 5 3/4″ using our metal back plates. 12s will not fit because of how the box fits around the rear window frame. The top of the box has an extra piece of trim to help keep give the subs more clearance between the box and the back of the seat. Some photos do not show it, but that is our new design.

This is a sealed subwoofer box. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. For customers who want louder deeper bass with the lower bass more pronounced. Because of the ported design, the bass will not be as tight and punchy, but there is double the bass of a sealed box with the same subs. If big bass is what you want then our ported box will be what you want.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickle plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.
