This MB Quart MBQJT-SS-ACC-24+ package bundles five components into a complete audio upgrade for the Jeep Gladiator (JT) from 2024 to current: the MBQJ-AMP-ACC-1, MBQJT-SUBA-1, MBQJ-48CRGB24+, MRGB-APP2, and NA4-400.2. Two 8 inch long-throw subwoofers sit in a rear underseat HDPE enclosure with 1.0 cubic feet of internal airspace, while a 400 watt full-range two-channel Class D amplifier and a 400 watt subwoofer amplifier deliver 800 watts of total system power.

Installation is plug-and-play using OEM harnesses and hardware, with signal harnesses covering 2018–2023 and 2024–current Wrangler (JL) and Gladiator (JT) model years, a power harness that supports up to three MB Quart NA2/NA4 amplifiers, and a 4-channel line output converter. The powered coated amplifier mount holds three amplifiers, the enclosure keeps full access to the jack and top parts, and no floormat modification is needed.
