Polaris RZR RS1 Audio System By MB Quart Now Shipping

June 2018 New Products

Chicago, IL – As the premier OEM audio brand for Polaris off-road vehicles, MB Quart has announced the completion of the new RZR RS1 Bluetooth Integrated 200 Watt Waterproof Audio System.

This collaboration between Maxxsonics Engineers on the MB Quart team and the Polaris engineering groups has delivered the only audio system designed exclusively for the RZR RS1.

Since the single seat, high horsepower RS1 was conceived, the demands to MB Quart product developers was clear: “Make it easy to install, make it loud and make it sound amazing.”

Alden Stiefel, president and CEO of Maxxsonics USA said, “We are several years into our relationship with Polaris now. The continued improvements to product integration within the vehicle designs and overall sound quality is a testament to the efforts of the engineering teams from both Polaris and Maxxsonics.”

The RZR RS1 Bluetooth Integrated 200 Watt Waterproof Audio System is available exclusively through Polaris and its network of dealers.

“Through our MB Quart brand, Maxxsonics is delivering the best sounding OEM and aftermarket audio products available to the Polaris dealer network and Polaris off-road vehicle owners,” Stiefel said.

The system contains:

  • Radial dial Bluetooth controller with aux input
  • 200 watt full range Class D amplifier
  • Two under dash 5.25-inch Mica filled, poly cone component speakers
  • Two top of dash 1-inch titanium dome tweeters
  • Full system harness with Polaris Pulse electrical
  • Required installation hardware

Brian Sherman, director of business development for Maxxsonics said, “Once again we are proud to partner with Polaris with our MB Quart brand for an OEM audio solution. We are all big fans of the RZR platform so when we had the opportunity to work with Polaris on the new RS1, we jumped at the chance.

“The system we designed for the RS-1 is probably the most integrated audio solution we have designed with Polaris to this point in our 6 year relationship.”

Key System Features

Bluetooth Control

Ergonomically engineered to be operated with minimal movement away from the steering wheel, the Polaris RZR RS1 audio system is operated by the innovative joystick controller. The unit easily installs in the switch hole, left of the ignition.


200 watt full range Class D amplifier installs in the lower right side panel with included bracket and hardware. The amplifier for the RS1 Audio system is a high power amplifier that is designed specifically to augment the component speakers for the vehicle. It is also fully potted, making it completely submersible. In electronics the potting process seals the components and PC Board in a waterproof compound.

The MB Quart engineers have incorporated the Q-Stasis preamp stage which provides ultra-low noise through the signal path. That low noise input is paired with the Class Q1 proprietary Full Range Class D Topology for a real sound quality powerhouse.


Component speakers deliver superior high-end sound quality over conventional 2-way or other coax style speakers through proper positioning of the tweeters.

Titanium Dome Tweeters

1-inch (29mm) titanium dome tweeters offer a much more musical sound quality over aluminum. It has very smooth high frequency with the added benefit of additional output and a broader frequency range.

Mica-Filled Poly Cones

The RS1 speaker system produces powerful deep midbass notes with a very musical midrange section which is very important to instruments and voices in the musical spectrum. The MB Quart engineers utilize a mica-filled polypropylene cone which gives the speaker incredible strength and improves the overall waterproof rating. Drivers are amazed at how loud this system can play.

Crossover Design

The RZR RS1 audio system uses an external high-pass and low-pass design. Improved separation between tweeter and mid/woofer are handled by the 12dB per octave Butterworth network crossover.

The separate crossover minimizes heat into the speaker voice coils and reduces crosstalk between crossover components on the small internal PC board. The crossover also includes tweeter protection circuitry to protect against distortion.

The mid/woofer components are installed under the dash while the tweeters are installed high on the dash which helps create a very large sound stage.


The engineering teams at Polaris and MB Quart consolidated the source unit in a Bluetooth controller, the system is augmented with the 200 watt amplifier, the 5.25-inch component speakers and 1-inch tweeters with the harnessing that terminates at the Polaris Pulse connector. This effort delivers incredible audio quality while remaining nearly invisible to those on the outside. With the placement of the Radial controller, you don’t need to take your hands far off the wheel to adjust the audio while all the other audio components and the harness of the system easily plug into each other and integrate into the RZR RS1. With the inclusion of the Polaris Pulse Connector, integration with the vehicles electrical is all on a single connector.
