Frequently Asked Questions
Does this kit work with the factory Ride Command system?
Yes. The SSV Works Phase-7 kit is fully compatible with Polaris Ride Command. The MRB4 receiver integrates with the Ride Command audio expansion input, allowing you to control audio from both the MRB4 and the factory touchscreen.
How long does installation take?
Most owners complete the full 7-speaker installation in 3-4 hours. The plug-and-play harness eliminates the need for custom wiring, and all mounting hardware uses existing cage and dash points on the Pro R, Pro S, and Pro XP chassis.
What's the difference between K-Spec and V-Spec?
K-Spec kits feature Kicker KM Series marine speakers, while V-Spec kits use SSV Works' proprietary WP Series speakers. Both deliver excellent performance; the K-Spec is tuned for Kicker's horn-loaded midrange design, while V-Spec is optimized for SSV Works' coaxial configuration.
