This MB Quart audio roof replaces the standard Polaris RZR roof with a complete 300-watt, 8-speaker sound system, so the music comes built into the vehicle rather than bolted on afterward. A 33-inch single-row Pro Armor LED light bar throws 5,300 lumens of combined spot and flood light, and the whole unit carries an IPX67 rating for water, dust and snow.

Everything runs from the center console: the AM/FM Bluetooth 4.0 source unit with Apple control drives the roof speakers and feeds four preamp outputs for adding Extreme Audio Pods, RZR Doors, a dash amp or a subwoofer. The high-strength UV-resistant poly shell mounts to the RZR with a reinforced six-fastener plate, and the 1-inch titanium dome tweeters, mica-filled poly cones and 6.5-inch coaxial rears are built to hold up through temperature swings on the trail.
