2007-13 GMC Yukon Sub Box Downfire Sealed Large Third Row


2007-13 GMC Yukon Sub Box Downfire Sealed Large Third Row

­The 2007-13 GMC Yukon, with its third row seat, has surprisingly little room for subs for a large SUV and this box is made to take up as much of that space as possible. This GMC Yukon Downfire Sub Box Third Row Seat design is for those who want the bass while keeping the third row seating. It has a maximum airspace of 4.2cuft with over 9” of mounting depth. Any number of subwoofer combinations can be made to fit what you want in the back of this SUV. There can be two or three 10s or two 12s in this downfire box to maximize the output while limiting lift gate rattle.

If you want to keep some sort of storage then the best compromise is to keep it tall and narrow, so feel free to contact us with special requests. We also offer this box in a ported design. Let me know what you want to do and what subs you have and I will see what I can do for you.

This is a sealed subwoofer box. 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. 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, but there is double the bass of a sealed box with the same subs. If big bass is what you want then our ported box will be what you want.

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.
