1999-2007 GMC Sierra Extended Cab Sub Box Single Ported

The 1999-2006 GMC Sierra Extended Cab trucks have a ton of space under that rear seat, so why not fill it up with subs? This sub box is designed to go under the driver side rear seat but could easily be made the other way to fit on the passenger side. It has 1cuft of airspace which is great for one 10 or 12. 8” subs could work, too, but the airspace is a little big for just 1, but 2 can work on this half box. Let me know what subs you want and what configuration you want and I can make it happen for you. Also if you need more than 6.5” of mounting depth I can do a combination of steel and wooden bumps to give more mounting depth.

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.
