MBQJT-SUBA-1

The MB Quart MBQJT-SUBA-1 is a dual 8-inch underseat subwoofer system with a matched 400 W Class D amplifier, built for the 2020-current Jeep Gladiator JT. Buying the two together removes the guesswork of matching amplifier power to driver capability, and the underseat location adds bass without touching bed space, cargo room, or rear passenger space. Two application specific long-throw 8-inch subwoofers cover 50 Hz to 250 Hz at 89 dB sensitivity and 4 ohm impedance. Power comes from a 400 W high efficiency compact Class D NA2 amplifier with on-board equalization, so you can shape output for an open-air cabin where bass behaves differently than in a sealed car. Class D efficiency also keeps current draw manageable. Installation uses OEM hardware, retains full access to the jack and top parts, and requires no floormat modification, so daily usability stays intact. Basic hand tools complete the job. Total system power is 400 W. Shipping weight is 27 lb with dimensions of 23.42 x 16.06 x 15.35 inches.
