MBQJT-SUBA-1 Dual 8" Underseat Subwoofer and Amplifier Kit for Jeep Gladiator

The MB Quart MBQJT-SUBA-1 packs two 8 inch long-throw subwoofers and a 400 W Class-D amplifier into an underseat kit built specifically for the 2020-and-newer Jeep Gladiator JT, adding real bass without giving up cargo space or floor room. Each subwoofer is application-specific to the Gladiator's underseat cavity, tuned from 50 Hz to 250 Hz at 89 dB sensitivity and 4 ohms, and the included NA2 amplifier runs both at 400 W total with onboard equalization already dialed in for the enclosure. Installation uses existing OEM hardware and mounting points, with full access preserved to the jack and factory underseat storage, and no cutting or modification to the floor mats required. Because both subwoofers and the amplifier are matched and pre-tuned for this specific vehicle, there's no guesswork in gain settings or enclosure sizing that comes with building a universal underseat box from scratch. Basic hand tools are all that's needed to complete the install.
