2001-2006 GMC Sierra Crew Cab Sub Box NonHD Ported

2001-2006 GMC Sierra Crew Cab Sub Box NonHD Ported ­The 2001-2006 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. This is a ported subwoofer enclosure. Ported subwoofer enclosures are 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 as a sealed box, but there is typically double the bass of a sealed box with the same subs and power. 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. If tight, punchy bass is what you want then our sealed designs will be what you want. This design is for maximum airspace and the airspace of the box can be reduced if desired. Our ported boxes are designed according to your subwoofer’s specifications. No two boxes will really be alike. At checkout, there is a “Comment” box, please give us the model number of your subs and we will build the enclosure as needed. We tend to tune our boxes low, around 34-37hz. If you have any specific requests, please feel free to let us know. 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.
