JL Audio SB-GM-SLVCC4/12TW3, Stealthbox for 2019-Up (Gen 4) Chevrolet Silverado / GMC Sierra 1500 Crew Cab Trucks
This generation of Chevrolet/GMC trucks is bringing new levels of interior refinement and technology to the full-size truck segment. Our Stealthbox® enhances all this by adding impressive, high-quality bass without losing any of your precious people space or interior functionality.
The Stealthbox® slips under the truck's rear seat and features two of our revolutionary 12TW3 thin-line subwoofers, giving you absolutely stellar sub-bass impact and quality. We even left a perfect spot in the middle of the enclosure for a clean, hidden amplifier installation!
