2001-2006 GMC Sierra Crew Cab Sub Box NonHD Sealed­

The 2001-2007 GMC Sierra Crew Cab 1500 trucks are pretty limited on sub options and behind the seat is my favorite. This box is designed to go full width behind the seat and requires the removal of the jack and mounting studs and the air vents on the sides of the rear cargo area need to either be trimmed or removed. The box is 1.5cuft but the mounting depth is limited to 4.5”, so 8s and 10s will fit fine but only shallow 12s will work well.

This is a sealed subwoofer enclosure. Sealed subwoofer enclosures have 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, a ported enclosure is what you want. Because of the ported design, the bass will not be as tight and punchy, but there is typically double the bass of a sealed box with the same subs and power. If big bass is what you want, then our ported designs 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.
