Description

Adding bass to a truck can be a very complicated problem to tackle, especially when building a box! We offer pre-built enclosures that are ready to be dropped into your 99-06 Chevy Silverado / GMC Sierra truck that offer unbeatable performance and sound quality that simply cannot be matched. This is a dual 10″ down firing model, why down firing? This style enclosure actually increase the SPL output of your subwoofers forcing the sound waves to travel up in down inside the cab before reaching the listener. The woofers are spaced off the floor so it's not possible for them to hit the floor while playing. It also keeps the subs out of view for security concerns. Overall you cannot find a better fitting or sound box. This enclosure features a special black spray on coating that is comparable to bed liner spray. It not only makes for a more cosmetically pleasing look but is also a protective water resistant shell! 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. 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 Chevy Silverado 99-06 Extended Cab to the get the max performance from every extra inch of wasted space. Specifications:

Perfect fit
Size: 12 Inch
Packaged carefully, still a couple dings, but I watched the carrier toss it over the fence. Regardless, fits perfect and sounds great with good subs.

Way bigger than expected. I ordered it for my grandson for his birthday, It was supposed to fit in the truck I ordered it for and it doesn’t. Disappointed that it doesn’t fit right. Its supposed to fit under the seat and it doesn’t.

Arrived right on time, and the spray in bedliner coating is really nice. The box came destroyed but the way they wrapped it and shipped it kept the speaker box protected. Very nice for the money and wouldn't hesitate to buy another in the future. Good quality box for the price
