Need a sub box for your Chevy truck? We now offer a dual 10" and dual 12" for the new body style Chevy Silverado / GMC Sierra 1500 Non-HD crew cab trucks! This enclosure is down firing which both increases the overall SPL output of the subwoofers and also keeps them out of view for security reasons. The enclosure will be compatible with a wide range of woofers but works best with entry level and flat piston woofers due to the limited mounting depth.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.
