2007-2013 GMC Sierra Crew Cab Sub Box Single Sealed

­­The 2007-2013 GMC Sierra Crew Cab brought a new design to the table with an open space under the rear seats compared to the previous body style crew cabs that are a jungle gym of bars and brackets. This box design offers a clean and simple look that has 0.9cuft of airspace with a wide range of mounting depth options. Without any sort of bumps on the back this box offers 5” for 10s and 4.5” for 12s. With a steel bump it jumps to 5.25” for a 10 and 4 7/8” for 12s. With a wooden bump and a steel bump on top it allows 5 7/8” for 10s and 5.75” for 12s. The box is 30” wide and has 1.5” of clearance between the subs and the floor.

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.
