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.\u003c\/p\u003e\n\u003cp\u003eAs 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; this Jeep Gladiator soundbar uses compression horn drivers.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRear overhead soundbar with four 8 inch compression horn speakers with 1 inch titanium dome tweeters\u003c\/li\u003e\n\u003cli\u003eComposite enclosure with an integrated MB Quart logo badge, built as a drop-in upgrade using the roof area around the B-pillar\u003c\/li\u003e\n\u003cli\u003eLightweight composite speaker frames for maximum airspace\u003c\/li\u003e\n\u003cli\u003ePolypropylene cones with temperature-stable butyl rubber surrounds\u003c\/li\u003e\n\u003cli\u003eInterchangeable colored grilles so you can match the soundbar to your Jeep\u003c\/li\u003e\n\u003cli\u003ePlug and play with MB Quart's MBQJ-STG4A-1 or MBQJ-STG4AH-1 Stage 4 audio systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eBuilt To Solve: A Weak Factory Rear Sound Bar in the Jeep Wrangler JL and Gladiator JT\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRear-seat sound that gets lost with the top or doors off\u003c\/li\u003e\n\u003cli\u003eA thin factory sound bar that cannot keep up once the front speakers are upgraded\u003c\/li\u003e\n\u003cli\u003eWanting more output overhead without cutting the roof area or fabricating mounts\u003c\/li\u003e\n\u003cli\u003eKeeping the rear speakers matched to an MB Quart Stage 4 front system\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eBest For: 2018-2023 Wrangler JL and 2020-2023 Gladiator JT Owners Building an MB Quart System\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOwners running, or planning, an MB Quart MBQJ-STG4A-1 or MBQJ-STG4AH-1 front system\u003c\/li\u003e\n\u003cli\u003eJeep owners who drive with the top off and want more rear output\u003c\/li\u003e\n\u003cli\u003eOwners who prefer a clean look with colored grille options instead of lighting\u003c\/li\u003e\n\u003cli\u003eOnly 2018-2023 model years; check the Fitment section and the sibling versions before ordering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: rear overhead replacement soundbar with enclosure\u003c\/li\u003e\n\u003cli\u003eSpeakers: four 8 inch compression horn, 1 inch pure titanium dome tweeters, 12dB high-pass crossover, frequency response 20Hz to 24kHz, sensitivity 92dB, 180W peak \/ 90W RMS\u003c\/li\u003e\n\u003cli\u003eSpeaker construction: composite frame, polypropylene cone, butyl rubber surround, Y30 iron ferrite magnet\u003c\/li\u003e\n\u003cli\u003eEnclosure: composite, integrated MB Quart logo badge\u003c\/li\u003e\n\u003cli\u003eLighting: none; interchangeable colored grilles included\u003c\/li\u003e\n\u003cli\u003eConnection: plug and play with MBQJ-STG4A-1 or MBQJ-STG4AH-1\u003c\/li\u003e\n\u003cli\u003eListed weight: 35.25 lbs; listed dimensions: 51 x 17.5 x 8.5 in\u003c\/li\u003e\n\u003cli\u003eInstall: basic hand tools\u003c\/li\u003e\n\u003cli\u003eColor: Black; warranty: 1 year\u003c\/li\u003e\n\u003cli\u003eMOPAR Part Number: 68727434AA\u003c\/li\u003e\n\u003cli\u003eManufacturer Part Number: MBQJ-48H\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eMB Quart lists this product for:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eJeep® Wrangler (JL) 2018-2023\u003c\/li\u003e\n\u003cli\u003eJeep® Gladiator (JT) 2020-2023\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMB Quart states this soundbar is currently not compatible with the Jeep Sky One-Touch Power Roof.\u003c\/p\u003e\n\u003cp\u003eThis is a Jeep (on-road vehicle) audio product, not a UTV part.
