2004-2008 Pontiac Grand Prix Sub Box Sealed

The 2004-2008 Pontiac Grand Prix has a huge trunk but there is no reason to loose all that space because of a subwoofer. This box is as wide and tall as I can make it so it is not as deep as most traditional sub boxes. This box is only 15” deep at the bottom and fits up nice and tight to the rear of the back seat. It is 2.5cuft of airspace and has 8 1/2” of mounting depth and is perfect for a couple of 10s or 12s sealed but can also be made into a nice ported box. If there is anything special you’d like done let me know and I will get it made 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 trunk 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.
