You don't have to compromise. You can have geat bass in your vehicle and still get rid of that big, ugly enclosure. MTX Custom Subwoofer boxes take advantage of the nooks and crannies in your vehicle. While delivering tremendous sound quality, they retain the factory look with these molded enclosures that are even color matched to your stock interior!

This box includes an MTX subwoofer. The price is right, the look is right, and it SOUNDS GREAT.
