SSV Works 2026 Polaris RZR Pro R 4 Ultimate Plug-&-Play 11-Speaker Factory Audio Upgrade Kit (UNPHASED-7)
The SSV Works UNPHASED-7 Audio Upgrade Kit represents the ultimate acoustic transformation for the 2026 Polaris RZR Pro R 4 Ultimate. While the vehicle features a high-output 1500-watt, 8-channel amplifier from the factory, the stock configuration ignores a massive portion of that potential power. This kit is meticulously engineered to unlock every available watt by replacing inferior factory speakers and populating unused channels with high-performance components. By optimizing the existing power source, this system provides a massive increase in volume and tonal depth without the high cost of an aftermarket amplifier.
This comprehensive 11-speaker package provides a total immersive experience specifically tuned for the Pro R 4 platform. The kit includes eight 6.5-inch full-range powersports speakers, two precision-tuned tweeters, and a powerful 10-inch subwoofer enclosure for the rear seat. By utilizing the factory amp's secondary subwoofer channel, the UNPHASED-7 effectively doubles the vehicle's bass output while retaining the original front subwoofer. This strategic design ensures maximum performance gains where they matter most, delivering crystal clarity and thunderous low-end response that remains distortion-free at high trail speeds.
Installation is designed for maximum efficiency, utilizing a true plug-and-play architecture that interfaces directly with the factory 10-inch Ride Command system. The weather-proof, marine-grade components are built to survive the harshest off-road environments, from deep mud to desert silt. With a bolt-down design that requires no major rewiring, this kit offers a professional-grade finish that looks like original equipment. Backed by a limited lifetime warranty, the UNPHASED-7 is the cleanest and most powerful way to upgrade the factory audio system for the long haul.
