About the MB Quart MBQR-STG5-RC-1

Rock out with Ride Command®

A Polaris RZR with Ride Command is one impressive ride already, but this MB Quart Stage 5 audio kit will take your stereo sound to a whole ‘nother level. With front and rear 8" speakers, a 2-channel amp, a mono sub amp, and a 10" subwoofer, this system will add some serious thump to your off-road adventures.

Rock out with Ride Command®

A Polaris RZR with Ride Command is one impressive ride already, but this MB Quart Stage 5 audio kit will take your stereo sound to a whole ‘nother level. With front and rear 8" speakers, a 2-channel amp, a mono sub amp, and a 10" subwoofer, this system will add some serious thump to your off-road adventures.

Ride Command is an amazing bit of technology, but the low-voltage output isn't ideal for great audio. MB Quart worked with the engineers at Polaris to design a system that produces outstanding sound. The system includes two vehicle-specific Ride Command adapters and amplifiers that are specifically designed to work with the Ride Command system.

MB Quart designed this entire package to fit right into your RZR, with no cutting and minimal hassle. It also comes with all the parts and pieces needed for a smooth, hassle-free installation. Each component is tough enough for trail duty, so you won't have to worry about your system getting swamped.

8" speakers with custom enclosures

The package includes a pair of 8" NH1-120B compression horn marine speakers that are built for off-road and marine use. The durable poly cones withstand moisture and sunlight, as do the 1" titanium diaphragm tweeters.

These all-weather speakers are really easy to install, too, thanks to the RZR-specific speaker enclosures included in this kit. These rugged enclosures bolt right in using the factory mounting holes with just a little bit of drilling.

Crank it up with cage-mount speakers

Out back, you'll have a pair of NHT1-120BPR cage-mount speaker pods loaded with 8" NH1-120B 8" speakers that are designed to fit your RZR. Swivel mounts mean you can point the sound where you want it on the trail or at the campsite.

This 2-channel amp has power to spare

MB Quart's NA2-400.2 amplifier packs a lot of power into a small package that's perfect for powersports applications. This rugged Class D amp delivers 200 watts per channel at 2 ohms, so your speakers will get the juice they need.

A big sub and a mono amp

This thunderous audio kit includes a marine-rated MB Quart 10" sub that replaces your RZR's glove box using the included direct-fit enclosure. The enclosure is made from a durable composite material that blends right in and stands up to life on the trail.

The power for this beefy sub comes from the MB Quart NA2-400.1 powersports mono amp. With on-board equalization and quick release connectors, this amp is a serious performer that's also easy to install.

Speakers & Enclosures

NH1-120B Speaker Pods: The MBQR-STG3-RC-1 includes two NH1-120B 8" compression horn drivers designed for use in your Polaris RZR. Combined with the the included speaker pod enclosures, the 8" compression horn drivers get mounted in the kick panel area, taking up as little leg room as possible.

  •  Woofer: The low-frequency driver consists of an 8" composite polypropylene cone with a temperature-stable Butyl rubber surround all mounted in a lightweight composite ABS and glass fiber frame. The driver also features a voice-coil made from high temperature copper, wound on a Kapton former, allowing the voice-coil to handle more power while remaining lightweight. A woven fiber composite spider help stabilize the cone and voice-coil.
  • Compression Horn: The 8" drivers feature a coincident mounted compression horn, improving overall volume by as much as +5dB over conventional speakers. A Wavelength Transparent Acoustic Lens improves midrange frequencies through the cone.
  • Dome Tweeter: The NH1-120B speakers include a 1" dome tweeter with a pure titanium compression diaphragm, producing a smooth musical response with high output while requiring minimal amplifier power.
  • Crossover: A 12dB/oct. Butterworth crossover offers a smooth transition from high to low frequencies with conformal coating and PTC (Positive Thermal Coefficient) tweeter protection.
  • Grilles: Each driver features a pre-attached composite grille, treated to resist UV sun fade and weather.
  • Marine Grade: Tested to the highest marine and powersports standards for resisting the elements, both NH1-120B drivers carry an IPX67 weatherproof rating, making them highly resistant to water, dirt, and UV rays.
  • Speaker Specifications: The 4Ω speakers can handle 90 watts RMS (180 peak). They have a frequency response of 20Hz - 20kHz (+/-10dB) and a sensitivity of 92dB.
  • Speaker Pods: The MBQR-STG3-RC-1 system includes two durable, high-impact HDPE composite enclosures that are custom designed to mount in the kick-panel area while taking up as little foot and leg room as possible. Each speaker pod includes a 11" section of speaker wire pre-run through the enclosures.

Note: Drilling new mounting holes will be required for installing the speaker pods into the kick panels.

NHT1-120BPR Speaker Pods: Two rear-mounted, weatherproof speaker pods are included that are pre-loaded with a pair of MB Quart NPT1-120BP coaxial 2-way weatherproof drivers and designed specifically for powersports installations. The composite speaker pods include integrated swivel-mount brackets that can be attached to either factory or aftermarket roll-cage tubing.
