The SSV Works Phase-6 K-Spec kit is a plug-&-play RZR Pro stereo system with its own radio for 2020-2024 Polaris RZR Pro XP, RZR Turbo R and RZR Pro R. It includes the SSV MRB4 4-inch Bluetooth radio with mounting kit, two Kicker KML 6.5-inch dash speakers, two Kicker KMXL 6.5-inch horn speakers in rear cage pods, a 10-inch SSV subwoofer in an under-dash enclosure and a 1400W 5-channel amplifier.
As a Polaris RZR stereo upgrade, this is a complete RZR stereo system in one box: radio, Kicker RZR Pro speakers front and rear, a RZR Pro subwoofer and the amp to run them. It covers RZR Pro XP stereo, RZR Pro XP audio and RZR Pro XP speakers upgrades, a RZR Turbo R stereo build or a RZR Pro R audio kit, and it is the radio version of the SSV Works RZR Pro Phase-6 K-Spec kit, for owners who want a RZR Pro stereo with radio rather than running from Ride Command.
SSV counts the subwoofer in its 5-speaker total: four 6.5-inch speakers plus one 10-inch sub. If your RZR Pro has Ride Command and you would rather keep it as the source, SSV sells a Ride Command version of this kit with no radio.

Built To Solve: Weak Or Missing Audio In The 2020-2024 Polaris RZR Pro
- Phone or portable speakers that cannot be heard over engine, wind and tire noise
- No usable bass at speed or at camp
- No dedicated source unit to run an aftermarket amplifier and speakers from
- Buying a radio, pods, speakers, an amp and a sub separately and hoping they fit and work together

FAQ
Does this RZR Pro kit include a radio?
Yes. The kit includes the SSV MRB4 4-inch Bluetooth radio with a mounting kit.
How many speakers are in the kit?
SSV calls it a 5-speaker kit, and that count includes the subwoofer: two Kicker KML 6.5-inch dash speakers, two Kicker KMXL 6.5-inch rear horn speakers and one 10-inch SSV subwoofer.
Which RZR Pro models does it fit?
SSV builds it for 2020-2024 Polaris RZR Pro XP, Turbo R and Pro R, 2-seat and 4-seat. The 2025-2026 RZR Pro platform has its own SSV kits.
Is the amplifier built into the radio?
No. The kit includes a separate 1400W 5-channel amplifier that powers the speakers and the 10-inch subwoofer.
How does it install?
SSV Works builds it as a plug-&-play kit with a wiring kit and mounting hardware and states no soldering, cutting or crimping is needed. SSV also posts tuning instructions for the 5-channel amplifier.
Should I buy this or the Ride Command version?
Choose this version if you want the kit to supply its own radio. If your RZR Pro has Ride Command and you want to keep it as your source, the Ride Command version uses the same Kicker speakers, sub and amp without a radio.
Why SSV Works
SSV Works calls itself the first company to integrate audio in side-by-sides, and it builds vehicle-specific UTV audio: factory-fit speaker pods, subwoofer enclosures, wiring and complete plug-&-play kits designed around each machine instead of adapting car or marine gear.
Complete Your 2020-2024 RZR Pro Stereo With Radio
Confirm your RZR Pro is a 2020-2024 Pro XP, Turbo R or Pro R and decide whether you want a radio or want to run from Ride Command before ordering the Phase-6 K-Spec kit. 4-seat owners can add a rear-seat subwoofer enclosure, and SSV sells a tweeter upgrade for the factory dash locations.
