We offer a specifically enclosure for Sedans and Coupes that just cannot be found elsewhere. What is the advantage to our enclosure? This single 10" sealed subwoofer box features a flat front where the subwoofer actually mounts and then the rear of the enclosure is slanted. This is convenient since most of the time when you push a standard square box against the rear seat in the trunk you have wasted space. However the slanted box can be pushed all way back against the rear seat and save precious trunk room! This enclosure is compatible with almost every sub brand and works best with entry to mid level subwoofer(s). Our boxes are made from precision cuts of MDF. They are then liquid nailed, nailed and completely sealed. We then wrap them with high quality carpet that matches most vehicle interiors. All Boxes feature high grade spring loaded terminal cup(s) for the absolute best connection possible. All the custom series enclosures are made to fit precisely into your vehicle to the get the max performance from every extra inch of wasted space. We guarantee you will not only see a difference in the quality of the boxes we build, but you will hear the difference and that is what is it is truly all about.
