1988-2002 GMC Sierra Crew Cab Sub Box Shallow Sealed

1988-2002 GMC Sierra Crew Cab Sub Box Shallow Sealed This subwoofer enclosure was designed to work on the 1988-2002 GMC Sierra Crew cab with a bench seat but will work on most standard cab trucks. This enclosure is full width at 61”x17x9 with 1.86cuft of airspace and has around 4 1/2”, so shallow-ish subs are a must. This design may not work if your truck has a center console. If you want to try to see if it will fit please measure first. 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 nickel 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. Chevy / GMC Gallery
