Description
Description
This MB Quart audio package is a complete, vehicle-specific upgrade for the Jeep Wrangler (JL) from 2018 to current, bundling a 400-watt Class-D subwoofer amplifier with a 12-inch high-output subwoofer. The subwoofer enclosure mounts to the interior tailgate panel using the included hardware, and the amplifier plate holds up to three MB Quart NA2/NA4 amplifiers for a clean, factory-style fit.
Installation is plug-and-play with OEM-style harnesses covering Wrangler (JL) and Gladiator (JT) model years 2018–2023 and 2024–current, and the kit includes a 4-channel line output converter and all necessary signal and power harnesses. The 12-inch subwoofer delivers a frequency response of 24Hz to 500Hz at 2 Ohm impedance with 86.6dB sensitivity, and only basic hand tools are needed for the install.
