About the MB Quart MBQJT-SUB-1

A solid foundation

Nothing beats a perfect fit, especially when it comes to finding space for bass, and MB Quart's MBQJT-SUB-1 loaded enclosure takes the guesswork out of installation with two 8" subs in a custom-fit box for your Jeep Gladiator. This specially designed enclosure fits perfectly underneath your backseat, replacing the underseat storage compartment, so you can achieve seriously stealthy bass in your Jeep.

Loaded for impact

MB Quartz uses a sturdy HDPE enclosure to house two "long-throw" subwoofers for maximum impact. The enclosure's 1 cubic foot of airspace ensures that your bass is tight and accurate.

Product Research

Features

Vehicle Compatibility: The MB Quart MBQJ-SUB-1 has been specifically designed to fit select 2020-up Jeep Gladiator (JT) vehicles. The custom subwoofer box mounts neatly under the rear seat using the OEM hardware, while still providing access to your jack and top parts. No modifications to your floor mats will be required either.

Enclosure: The custom MB Quart enclosure is constructed of high-quality HDPE (High Density Polyethylene), with 1.0 cu. ft. of internal airspace. It features a molded center support for added structural integrity. The enclosure has been configured to mount underneath the rear seat, in place of the OEM storage compartment, so no usable passenger space is taken up.

Note: The MBQJ-SUB-1 replaces the OEM under-seat storage compartment.

Power: The MB Quart subwoofer enclosure can handle 500W RMS (1000W peak) on its single 4Ω input.

Dual 8" Subwoofers: The MBQJT-SUB-1 is outfitted with two MB Quart 8" long-throw woofers for powerful bass. The subwoofers feature an injection-molded, polypropylene cone with a rubber surround for added durability, excursion and bass response. The two 8Ω woofers are wired in parallel for a 4Ω load on the single input harness. A built-in 4" wiring harness with 2-pin Molex connector, along with a matching 4" Extension Harness, is provided for the input, letting you plug directly into select MB Quart amplifiers (sold separately). If connecting to another brand of amplifier, the Molex connector can be cut off and the bare-ended wire used.
