This Stage 5 audio system is MB Quart's top-of-the-line RZR audio system. Designed to fit select 2014-up Polaris RZR models, the system includes a marine receiver and dash kit, four 8" speakers, custom speaker pods, a 10" subwoofer, two compact amplifiers, and all the hardware you'll need for a hassle-free installation.
MB Quart's GMR-3 marine digital media receiver packs a ton of features into a compact design that's made for the outdoors. And it fits into a custom dash kit that's made for your RZR. You can tune in to AM/FM radio, of course, but the big deal is built-in Bluetooth® that lets you stream music from your smartphone or other Bluetooth-enabled device. The GMR-3 is Apple-ready too, so you can access the iTunes collection on your iPhone®, iPod®, or iPad®. You can also use the rear aux input for your music player, or plug a thumb drive into the rear USB port to enjoy your favorite music.


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 RMS per channel at 2 ohms, so the four speakers will get the juice they need. For the 10" subwoofer, there's an MB Quart NA2-400.1, a compact 400-watt mono amp with plenty of juice. This marine-rated Class D amp boasts a MOSFET power supply, an aluminum heat sink, and nickel-plated inputs, plus on-board equalization and three-stage protection circuits. Quick-release connectors make installation quick and easy.
