The SSV Works UNPHASED-6 is an 8-speaker factory audio upgrade for 2026-2027 Polaris RZR Pro R Ultimate and 2027 RZR Pro S and Pro XP Ultimate trims that came from Polaris with factory Rockford Fosgate audio. It replaces the factory speakers with two tweeters and six 6.5-inch full-range speakers, keeps the factory front subwoofer, and runs from the factory 1500-watt, 8-channel amplifier and 10-inch Ride Command display.
SSV Works says the factory setup only uses about half of that amplifier and that the factory speakers hold the system back. This RZR Pro R speaker upgrade puts better speakers on the factory amp instead of adding an aftermarket amplifier, so the factory Ride Command integration stays in place.
As a RZR Pro R audio upgrade and RZR Pro R 8 speaker kit, the SSV Works UNPHASED-6 is a RZR Pro R speaker kit with more RZR Pro R speakers than UNPHASED-5, and doubles as a RZR Pro XP audio upgrade or RZR Pro S audio upgrade on 2027 Ultimate trims. It builds a fuller Polaris RZR Pro R sound system as a Rockford Fosgate speaker upgrade for the RZR and a Ride Command speaker upgrade, keeping the SSV Works RZR Pro R audio on the factory amp.
The factory front subwoofer stays because it already uses the amplifier's 400-watt at 4-ohm subwoofer channel. On 4-seat models, SSV's rear-seat 10-inch subwoofer enclosure can be added separately to use the amplifier's unused second subwoofer channel.

No. UNPHASED-6 is a speaker upgrade that runs on the factory Polaris 1500-watt, 8-channel amplifier and factory 10-inch Ride Command display, and it keeps the factory front subwoofer. None of those are included, and the kit requires the factory amp and display.
Will it work on a RZR Pro R without factory audio?
