MBQJ-AMP-ACC-1 Jeep Wrangler JL / Gladiator JT Line Output Converter Kit
The MB Quart MBQJ-AMP-ACC-1 is a vehicle specific line output converter kit designed to add one or more amplifiers to the factory audio system in Jeep Wrangler JL and Gladiator JT models. Built to support subwoofer and soundbar amplifier upgrades, it combines model specific harnessing, a 4 channel LOC, and amplifier mounting support in one package.
Overview
Factory Audio Integration for Jeep Amplifier Upgrades
The MBQJ-AMP-ACC-1 is built to tap into the OEM Jeep audio system and simplify the process of adding aftermarket amplifiers for a subwoofer and or soundbar. Rather than piecing together separate integration parts, this kit combines the main signal conversion and harnessing pieces needed for a cleaner install path.
MB Quart also includes application specific harnessing for different Jeep model year groups, along with a power harness that works directly with MB Quart NA2 and NA4 amplifiers.
