Made-to-Order Under-Seat Enclosure for 2014-Up Chevrolet and GMC Trucks
The SMS Precision Series Four-8 Under-Seat Enclosure is built for compatible Chevrolet Silverado and GMC Sierra crew-cab trucks using four 8-inch subwoofers beneath the rear seat.
Each enclosure is produced to order. The bare-wood option lets the customer apply their own stain or finish, while finished versions can be coordinated with the rest of the vehicle or audio build.
Fitment
- Chevrolet Silverado and GMC Sierra crew-cab applications beginning with the 2014 body style
- Four 8-inch subwoofer layout
- Under-rear-seat installation
Exact year, cab configuration, seat structure, storage tray, floor contour, subwoofer depth, and required seat lift must be confirmed before ordering.
