Happy with the factory stereo and just want to add some extra clarity or output? MTX will also offer add-on packages that work with the OE audio components. The ProXP-20-SW kit comes with a loaded 10-inch ported subwoofer enclosure, 600-watt monoblock amplifier, amp mounting system, and complete plug-and-play wiring harness. This is a direct bolt-on subwoofer kit for your 2020 or newer RZR Pro XP that lives under the dashboard. The second system replaces the front speakers of your factory Polaris stereo. The ProXP-20-FS kit includes two RGB 6.5-inch midrange drivers and two soft dome tweeters. Each speaker mounts into the preexisting speaker location. The kit comes with four IP66-rated all-weather speakers, mounting hardware, and the OE interface wiring harness already built in. It does not include the RGB control module that’s sold separately.
