OPEN BOX — MB Quart MBQJL-302 12-Inch Jeep Wrangler Tailgate Subwoofer System
Upgrade the bass in a Jeep Wrangler without sacrificing cargo-floor space. The MB Quart MBQJL-302 packages a vehicle-specific, ported 12-inch tailgate enclosure with a matching 400-watt Class-D subwoofer amplifier.
Manufacturer-Specified System
- One 12-inch subwoofer in a molded, ported tailgate enclosure
- One 400-watt Class-D subwoofer amplifier
- Tailgate mounting hardware and subwoofer-to-amplifier wiring supplied as part of the manufacturer's complete kit
- Designed to integrate with compatible MB Quart Jeep Stage 4 (JL) or Stage 2 (JK) systems
Vehicle Application
MB Quart lists the MBQJL-302 for Jeep Wrangler JL (2018–current) and Wrangler JK (2007–2018). Installation depends on year, factory audio equipment, compatible amplifier mounting and signal/power wiring. MB Quart specifies the amplifier mounting plate as part of a compatible Stage 4/Stage 2 kit, not necessarily this standalone MBQJL-302 box. Confirm fitment and integration parts with SMS Car Audio before ordering.
