2007-2013 GMC Sierra Extended Cab Sub Box Single Ported
The 2007-2013 GMC Sierra Extended Cab offers some difficult challenges of it’s own. The space under the seat is tall, but it changes floor levels 3 times and each side of the transmission tunnel is different. As the floor goes up the mounting depth goes down. The box I have designed is .8cuft total with .5” of mounting depth for 10s and 5.25” for 12s with an included double bump of 3/4” MDF and a steel plate on top. I prefer to do my added depth this way instead of building a little box on top of the box. That little box is just more joints to go bad and fail. My double bump may cost a few bucks more but it is bullet proof.
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.
