MB Quart Stereos

MB Quart Stereos: Where German Audio Heritage Meets Off-Road Durability

When it comes to source units that can handle both audiophile-grade sound and the punishment of the open trail, MB Quart stands in a class of its own. High-quality audio reproduction has been synonymous with MB Quart's products since the company was founded in 1962. The MB Quart brand is owned by Maxxsonics and is based near Chicago, IL, but its engineering DNA traces back to professional studio equipment built in Obrigheim, Germany — a heritage that still shows in every stereo the brand produces today.

Built for the Environments That Destroy Ordinary Stereos

What separates an MB Quart stereo from a standard car head unit is its unwavering focus on ruggedness without sacrificing sound quality. MB Quart is a leader in premium audio systems for powersports, delivering crystal-clear sound in the most rugged environments, with products built to withstand the elements while providing powerful, high-quality audio for UTV enthusiasts. Whether you're navigating a rocky trail, hauling across open water, or cruising on an ATV, an MB Quart stereo is engineered to keep performing where ordinary units would fail.

A prime example of this approach is the MB Quart 7-inch touchscreen receiver. It features a versatile marine/UTV design with Bluetooth streaming and an IPX67 waterproof rating for reliable performance anywhere. Premium audio customization options include dual-zone audio control, a 10-band EQ, and dedicated subwoofer adjustments for a powerful, tailored listening experience on any terrain. The unit is also equipped with 2 video inputs, 1 video output, and an integrated auxiliary switching system, with a high-contrast LED touchscreen featuring customizable RGB lighting plus AM/FM/weather bands.

Seamless Connectivity and Smart Integration

Modern MB Quart stereos are designed for the way today's riders and boaters actually use technology. Quick-Pair Bluetooth, dual USB ports, and wired inputs make connecting phones and media effortless, giving you instant access to your favorite music. Many models in the lineup also support wireless Apple CarPlay and Android Auto, so navigating or streaming from your smartphone is as intuitive on the trail as it is in the car.

For powersports enthusiasts who want a complete, plug-and-play solution, MB Quart pairs their source units with purpose-built systems. Their GMR-LCD source unit offers AM/FM, waterproof Bluetooth with built-in amplification, and Android and Apple control — with fitments covering popular platforms like the Polaris RZR 900, 1000, XP Turbo, and XP4 series. These integrated packages make it straightforward to upgrade your ride's audio without complex custom fabrication.

A Legacy That Informs Every Source Unit

Throughout the 1990s, MB Quart became the brand to beat in sound quality competitions, with their car audio products dominating IASCA and EMMA competitions worldwide. That competitive engineering mindset carries forward into their stereo lineup today. Every MB Quart head unit is conceived as the nerve center of a larger, high-performance audio system — tuned to work synergistically with MB Quart amplifiers, speakers, and subwoofers for the most cohesive sound possible.
