Thinking about add some bass into your Colorado or Canyon? We offer a custom fit dual 10" or dual 12" sealed enclosure that is specifically for the extended cab Chevy Colorado / GMC Canyon truck. This is a down firing enclosure that both increases the overall SPL output of the subwoofers and keeps the woofers out of view for security reasons. The rear seating is no longer useable once the enclosure is installed but who needs seating when you have bass!!!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.
