JL Audio Stealthbox Subwoofer Enclosure for 2019-Up Chevrolet Silverado / GMC Sierra 1500 Crew Cab Trucks and 2020-Up 2500 / 3500 Crew Cab Trucks

Deep, effortless bass that lives where you'd never expect it. The JL Audio Stealthbox pairs two 12-inch TW3 thin-line subwoofers with a custom-molded sealed enclosure engineered to disappear under your rear seat — no fold-up bench, no shaved-down truck box, no compromise.

This is the payoff of JL Audio's thin-line subwoofer technology: full, articulate sub-bass from drivers slim enough to hide in a space most subs can't touch. The rugged, form-fitting enclosure is molded specifically for the Crew Cab platform, so it drops in clean and stays put. We even left room on the box for a tidy, hidden amplifier install — your whole system, completely out of sight.

Your rear seat still folds. Your rear leg room stays exactly where it was. And your truck sounds like it's hiding something, it absolutely is.
