2007-2013 GMC Sierra Crew Cab Sub Box Double Up Fire Ported

­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 1.6cuft with around 5” of mounting depth in an up fire design. With an up fire box you don’t get the same acoustic loading that you do from a down fire, but you do get a more precise reproduction of the music. Meaning you get less coloration from the vehicles design, if you’re more of a music purist then you’ll prefer the up fire design.

This is a ported subwoofer box. Ported subwoofer boxes 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 double the bass of a sealed box with the same subs. 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 box will be what you want.

This is our ported design. 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 subwoofers 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 box as needed. We tend to tune our boxes deep, 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 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.
