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 12″ 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.

  • Not feeling it!
Size: 12 Inch
I say this because I really wanted this to sound great. Honestly, it did not come close to what I was trying to achieve. Let's face it. We want our system to be head turning, over the top, bass you can feel in your grill. Unfortunately, this isn't the box for you. I liked the fact that my subs would be hidden from prying eyes, but that's all the pros this box has. I can't tell you what it's tuned to alls I know is it made my CT Ozone's sound like they were underwater. It literally deadened all the performance I wanted to try and emphasize. Granted I could feel it in my seats, but I could no longer hear any of it outside the vehicle. I mean absolutely none. It was a handsome enclosure, it did hide and hold my subs, and the appearance was master full. It just sounded weak. So out came the old Rockford Fosgate box with duel ports. Hell with hiding them, if I can't enjoy them. Back on the rear seats. Sorry box makers, this customer wasn't satisfied with looks alone. I want DB's, and shake the fillings out my teeth. I will be sending back. ... show more

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
