  • Skar Audio engineered this custom fit, vehicle specific, Dual 12-inch sealed subwoofer enclosure specifically for 1999-2006 Chevrolet Silverado and GMC Sierra Extended Cab trucks. This enclosure features an OEM design that allows it to fit perfectly under the rear seat bench in the cab of the truck - with absolutely no modifications required. With this subwoofer enclosure we provide a custom solution for you to be able to add a system to your truck without any of the headache that most face in pursuit of this goal.

    The sealed, down-firing, under-seat design of this enclosure allows for maximum bass, while preserving the limited cargo space most users are reluctant to give up. Our custom-fit enclosures raise the bar when it comes to strength and reliability; constructed entirely out of premium medium-density fiberboard (MDF) and other world class materials. Our vehicle specific subwoofer enclosures are engineered from the ground up, with every detail carefully analyzed to ensure perfect fitment and compatibility. Furthermore, they are finished in a premium black trunk-liner carpeting, allowing to blend in with your vehicles interior.

The box was exactly what I was looking for. Fits perfect and sounds amazing. Before installing did a test fit in his single cab 2004 Chevy and faced it forward. Sounded amazing in his truck as well. Good quality product especially for the price!
