The MB Quart MBQJ-48HRGB is a Jeep Wrangler sound bar replacement for the 2018-2023 Wrangler JL and 2020-2023 Gladiator JT: a rear overhead soundbar with four 8 inch compression horn speakers with 1 inch titanium dome tweeters and RGB LED lighting that directly replaces the factory rear speaker sound bar. It drops into the roof area around the B-pillar and plugs into MB Quart's Stage 4 front systems.
The factory rear sound bar is the speaker location closest to the back-seat passengers, and on a Jeep with the top off it has to compete with wind and road noise. This soundbar swaps it for four 8 inch drivers in a composite enclosure. MB Quart lists it as direct plug and play with the MBQJ-STG4A-1 and MBQJ-STG4AH-1 Stage 4 kits; it is the rear half of a system, not a stand-alone powered speaker.
As Jeep Wrangler overhead speakers go, a full Jeep sound bar replacement changes more than a speaker swap, and the same MB Quart soundbar fits the Jeep Gladiator, so this Jeep Gladiator sound bar shares its parts with the Jeep Wrangler soundbar. Compared with smaller Jeep soundbar speaker swaps, an MB Quart soundbar replaces the whole bar and uses compression horn drivers rated 180W peak / 90W RMS.

FAQ
Does the MB Quart MBQJ-48HRGB soundbar need its own amplifier?
Yes. MB Quart lists it as direct plug and play with the MBQJ-STG4A-1 or MBQJ-STG4AH-1 Stage 4 kits, which supply the amplification. If you are keeping the factory front speakers, MB Quart's soundbar accessory packages (MBQJ-48CRGB-ACC-1 and MBQJ-48CRGB-ACC-24+) pair its RGB coaxial soundbars with the MBQJ-AMP-ACC-1 line output converter kit and an NA4-400.2 amplifier.
Which Jeeps does this soundbar fit?
MB Quart lists Jeep® Wrangler (JL) 2018-2023, Jeep® Gladiator (JT) 2020-2023. It is not the 2024-current version; for 2024 and newer Jeeps MB Quart sells the MBQJ-48CRGB24+.
What is the difference between the horn and the other MB Quart Jeep soundbar versions?
MB Quart offers the 2018-2023 JL / 2020-2023 JT soundbar with 8 inch coaxial speakers (MBQJ-48C, 140W peak / 70W RMS) or 8 inch compression horn speakers (MBQJ-48H, 180W peak / 90W RMS), each with or without RGB lighting, plus an empty enclosure (MBQJ-48E). The 2024-current version is the MBQJ-48CRGB24+ with addressable RGB.
Where does the soundbar mount and do I need to cut anything?
MB Quart describes it as a drop-in upgrade that directly replaces the OEM rear speaker sound bar, using the roof area around the B-pillar. MB Quart rates the install as basic hand tools; follow the MB Quart install manual for your model.
How does this soundbar connect to the rest of the system?
It is designed to plug directly into the MBQJ-STG4A-1 (factory radio) or MBQJ-STG4AH-1 (aftermarket radio) Stage 4 system, which supplies the amplifiers and front speakers.
How do I control the RGB lighting?
MB Quart pairs its Jeep RGB soundbars with its own app-based LED controllers in the stage packages (MRGB-APP for RGB, MRGB-APP2 for addressable RGB). The controller is not listed as included with the stand-alone soundbar, so check the controller separately.
Why MB Quart
MB Quart builds vehicle-tuned audio packages for the Jeep Wrangler JL and Gladiator JT, engineered around the factory mounting locations and wiring so the upgrade installs with basic hand tools instead of custom fabrication. MB Quart sells its Jeep kits in stages, so you can start with one piece and add matching speakers, subwoofers or a soundbar later.
Complete Your Jeep Wrangler JL Soundbar Upgrade
Before ordering this Jeep soundbar, confirm your model year against the Fitment section: the 2018-2023 (JL) / 2020-2023 (JT) versions and the 2024-current version are different parts. Then plan the power side: pair it with an MB Quart Stage 4 front system, or with MB Quart's line output converter kit and amplifier if you are keeping the factory front speakers.
