Compact Bass Performance Solution. The Single 12-Inch Under Rear Driver Seat Down Firing Subwoofer Box is engineered to deliver tight, punchy bass in a space-saving design for your Silverado 1500 Extended Cab. Designed to fit discreetly beneath the rear driver side seat, this enclosure offers improved low-end response while preserving cabin space. It's the ideal audio upgrade for those seeking performance without sacrificing interior room.
Construction and Appearance. Built from durable 5/8-inch MDF and finished with a high-pressure polyurethane bed liner coating, this enclosure is tough and resistant to wear. The sealed design prevents air leaks, enhancing output and clarity. With 0.73 cubic feet of internal air volume and a 6-inch mounting depth, it supports most 12-inch subs while protecting the cone from contact with the seat thanks to its down-firing layout.
Installation. Installation is simple and requires no permanent modifications. Just slide the box into place under the driver-side rear seat and connect your wiring for an instant audio upgrade.
Application. This Single 12-Inch Under Rear Driver Seat Down Firing Subwoofer Box fits 1999-2006 Silverado 1500 Extended Cab.
