JL Audio Stealthbox SB-J-WRNGL4G/12TW3 12" Subwoofer for 2024–Up Jeep Wrangler Unlimited 400W RMS 2Ω 010-03948-00

JL Audio Stealthbox SB-J-WRNGL4G/12TW3 is the newest-generation vehicle-specific enclosed subwoofer upgrade engineered exclusively for the 2024-Up Jeep Wrangler Unlimited (4-door). Mounting solidly above the driver-side rear wheel well, this Stealthbox delivers deep, controlled bass without consuming valuable cargo space — ideal for OEM+ and aftermarket audio system builds.

The enclosure features a 12" TW3 thin-line subwoofer rated for 400 W RMS and pre-wired to a 2 Ω mono load. TW3 technology offers strong excursion and surface area performance in low-clearance environments, enabling serious low-frequency output within a compact sealed enclosure. A steel mesh protective grille is included to support cargo-area utility without sacrificing durability.
