SSV Works 2026 Polaris RZR Pro R 4 Ultimate Plug-&-Play 8-Speaker Factory Audio Upgrade Kit (UNPHASED-6)
The SSV Works UNPHASED-6 Audio Upgrade Kit is the premier choice for riders looking to maximize the 2026 Polaris RZR Pro R 4 Ultimate entertainment system. While the vehicle arrives with a high-wattage 8-channel amplifier, the stock configuration ignores a massive portion of that available power. This kit unlocks that hidden potential by replacing low-fidelity factory components with high-output speakers specifically engineered to utilize every unused channel. By optimizing the existing power source, this system provides a dramatic increase in volume and tonal depth without the complexity or cost of installing a secondary aftermarket amplifier.
This comprehensive upgrade focuses on seamless integration and professional-grade performance. The UNPHASED-6 kit adds critical front door speakers and upgrades existing drivers to provide a true surround-sound experience on the trail. It features eleven total speakers, including six 6.5-inch full-range powersports speakers and precision tweeters that deliver crisp highs and punchy midbass. Because the system is tuned specifically for the Pro R 4 platform, it maintains full compatibility with the 10-inch Ride Command unit while significantly reducing distortion at high volumes.
Installation is engineered to be as rugged as the vehicle itself, utilizing a plug-and-play architecture that connects directly to factory wiring harnesses. The weather-proof construction ensures that the audio system thrives in mud, water, and dust. For those seeking maximum impact, the kit is designed to support the addition of a second 10-inch subwoofer, doubling the low-end output by tapping into the amplifier’s secondary sub channel. This entire package is backed by a limited lifetime warranty, ensuring that the soundtrack to the ride is as reliable as the machine.
Features
- Factory Amp Upgrade: Unlocks more of the factory 1500-watt, 8-channel amplifier by adding speakers where Polaris left channels unused
- Plug-&-Play Install: Uses factory audio wiring for a clean installation, with only the RGB wiring needing to be run
- 8-Speaker System: Includes two tweeters and six 6.5-inch full-range speakers
- Double the Bass Output: Add the rear subwoofer to use the amp’s second 400-watt sub channel, effectively doubling subwoofer power (compatible with the Pro R 4 Only)
- Smart System Design: Retains the factory front subwoofer because replacing it on factory power adds cost, not performance
