High-Impact Bass Enclosure. The Dual 10-Inch Under Rear Seat Down Firing Subwoofer Box is engineered to dramatically boost your Silverado's audio performance. Designed for extended cab models, this subwoofer enclosure maximizes bass response—up to four times louder than standard setups—while maintaining a discreet fit under the rear seat. It offers a clean, down-firing design that enhances low-frequency output and cabin sound quality.
Construction and Appearance. Built from rugged 5/8-inch M.D.F, the box is armor coated in high-pressure polyurethane bed liner material for enhanced durability and sound integrity. The coating also stiffens the enclosure to prevent air leaks, while maintaining a sleek, functional appearance. It features dual chambers with 0.71 cubic feet of air space per side and supports subwoofers up to 5.5 inches deep.
Installation. Installation is easy and requires no modifications to the truck. Simply slide the enclosure under the rear seat and secure your subs for a quick and effective sound upgrade.
Warranty. This subwoofer box is backed by a lifetime warranty.
Application. This Dual 10-Inch Under Rear Seat Down Firing Subwoofer Box fits 1999 to 2006 Silverado 1500 Extended Cab.
