Review on Atrend Bbox A151-12CP Single 12" Sealed Carpeted Subwoofer Enclosure - Compatible with 1999-2007 Chevrolet/GMC Silverado/Sierra Extended Cab, in Charcoal Finish by Phil Oliveira

After placing the box under the back of the driver, I had no problem working with my latest subwoofer. After installing Sundown I had nothing but problems. First, when my box is placed in the down position under the seat, my subwoofer touches the floor, making it impossible for me to use the space under the seat. Second, the box started making noises. In my opinion it would be better to go for a higher quality box, although for the price it's not a terrible box.
