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.
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.

This box fit perfectly under my back seat in my Z71 extended cab LT Silverado. It is very quiet and looks beautiful. Been in my truck for 6 months and hasn't had the first rattle or vibration noise. So pleased with the cost and the shipment was packed and protected with precision. Very easy to install and the quality is awesome.

Exactly as advertised! Fits my 2002 Gmc sierra extended cab like a gem. Sounds great and the box is very clean overall no rough corners etc and really nice covering work.

Great fit in my '05 extended cab Silverado... I was even able to put on speaker grilles without them being in the way... At first I was skeptical about downward firing speakers.... but they sound great... I get lots of bump out of them

Right off the bat this box fits perfect. My only complaint is that in the center portion of the box that fits over the hump of the back seat it is blocked off on the inside. I had to wire my subs to my amp as if it was two separate boxes. If you want to bridge the two subs you have to somehow manage to drill a hole on that wall block inside. Other then that it works great. I am running some kicker cvx’s and they fit amazing. I would complain about the lack of air space but you can do much about that without porting or sacrificing leg room.

Solid box. Put 2 10" early model sony xpoldes and they sound pretty good. You can't hear the subs much outside of the truck which is what I wanted, but it still shakes the hell out of my rearview mirror and gives nice bass. My only complaint was the speaker wire connectors were a little tarnished and low quality but meh.. I think I got what I paid for. Shipping was also pretty smooth/fast. I would recommend buying these if you don't want to spend a lot. Overall.. I feel I mad a good buy and the box is what I was looking for!
