Description

2007–2013 Silverado / Sierra Crew Cab — 2 × 6.5-Inch / Bare Wood

Sale unit: One custom underseat enclosure. Subwoofers, amplifier, seat-lift hardware where required, wiring, and installation are not included unless specifically stated.

Choose this two-driver 6.5-inch layout when the system is built around a pair of compatible 6.5-inch subwoofers and a straightforward amplifier/final-impedance plan.

Bare Wood leaves the enclosure unfinished for later finishing or additional fabrication. A rear-seat lift is required on 2007–2013 applications; lift hardware is not included. Exact driver cutout, frame, mounting depth, terminals and enclosure requirements are verified before fabrication.
