Custom Gmc Sierra Ext Cab 07-13 Truck Dual 10 Subwoofer Bass Speaker Sub Box

We finally have a custom fit enclosure available for the new body style 07-13 Chevy Silverado / GMC Sierra extended cab truck! This dual 10 enclosure is designed to fit under the rear bench seat and is a down firing model. Why down firing? Not only does it help improve the overall SPL output of the subwoofers but it also keeps the subs out of view for security reasons. This enclosure is compatible with a wide range of sub brands and model but entry level and flat piston subwoofers tend to work best.

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 07-13 GMC Sierra Extended Cab 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.
