JL Audio SBX-J-JTGLAD/10TW1 Stealthbox® Enclosed Subwoofer is a vehicle-specific under-seat subwoofer system built for the 2020-up Jeep Gladiator (JT). This rugged sealed enclosure mounts neatly beneath the rear seat and comes loaded with two 10TW1-4 thin-line 10" subwoofers, delivering strong low-frequency output while preserving rear passenger comfort and keeping cargo space untouched.
Rated for 600 W RMS and wired for a 2 Ω final load, this Stealthbox is a serious bass upgrade for Gladiator builds that need clean output without giving up daily usability. Installation requires removal of the under-seat storage compartment if equipped, while retaining the factory hardtop hardware storage box and jack stowage.
