JL Audio SB-GM-5GSUV/10TW3 Stealthbox® Enclosed Subwoofer is a vehicle-specific subwoofer system built for 2021-up Chevrolet and GMC full-size SUVs. This rugged, custom-molded sealed enclosure installs invisibly behind the driver-side rear cargo trim panel and factory grille, replacing the OEM “subwoofer” system if equipped while preserving usable cargo space.
Loaded with one 10TW3-D4 10" thin-line subwoofer, this Stealthbox is rated for 400 W RMS and wired for a 2 Ω mono final load. It is designed for clean, controlled sub-bass output in full-size GM SUV builds where factory-style fit, hidden installation, and real low-frequency performance all matter.
