MB Quart makes audio for one vehicle at a time: direct-fit speakers, subwoofers, overhead soundbars and complete Stage kits that install with plug-n-play wiring harnesses.
TrailRecon carries 38 MB Quart parts for the Jeep Wrangler JL and JK, Gladiator JT, Ford Bronco and Maverick, Toyota Tacoma (2016-2023) and 4Runner, and the Mercedes-Benz Sprinter W907. That includes Stage 2, 4 and 6 systems, tuned component and coaxial speakers, a tailgate subwoofer for the Bronco, a rear storage subwoofer for the Maverick, overhead soundbars for the JK, JL and JT, and a Sprinter Stage 6 kit with a 10 inch subwoofer and a 700 watt amplifier that sit under the passenger seat.
Check what radio the rig has before picking a kit. Some Stage kits work with the factory B&O system, some with a non-amplified factory head unit and some need an aftermarket radio. Years matter too: JL and JT soundbars change for 2024, and the Bronco Stage 6 has a 2025-2026 version. The JK Stage 2 is front speakers and amps only, with rear speakers or a soundbar sold separately. On a Sprinter, the space under the passenger seat has to be cleared first.
