Unleash Your RZR's True Audio Potential with the SSV Works 11-Speaker Factory Audio Upgrade Kit

Unlock the Power Polaris Left on the Table

Your Polaris RZR Pro R 4 Ultimate comes standard with a massive 1500-watt, 8-channel factory amplifier, but here is the catch, Polaris left nearly half of that power completely unused. With empty amplifier channels, cheap paper cone speakers, and zero rear bass, the factory setup barely scratches the surface of what it can do. Built exclusively for the 2026 Polaris RZR Pro R 4 Ultimate, this high-performance SSV Works 11-Speaker Factory Audio Upgrade Kit steps in to reclaim that wasted power. It maximizes your existing system to deliver a full-throttle, high-fidelity surround sound experience that will make your machine the loudest rig on the trails.

A Massive, Full-Cabin Sound Stage

Get ready to experience immersive, concert-quality sound even at wide-open throttle. This comprehensive upgrade delivers unmatched clarity and power throughout your side-by-side:

• 11-Speaker Powerhouse: Features a massive array including two high-output tweeters, eight premium 6.5-inch full-range speakers, and a heavy-hitting rear-seat 10-inch subwoofer.
• Double the Bass Output: By adding the dedicated rear-seat subwoofer to the factory amp’s second 400-watt sub channel, this kit effectively doubles your subwoofer power for chest-pounding low end.
• Unlocks the Factory Amp: Connects directly to the unused channels on your factory 1500-watt amplifier, utilizing the extra power to drive more speakers without the massive cost of buying an aftermarket amp.

SSV Works designed this kit to give you maximum audio performance with an incredibly straightforward, factory-integrated installation:

• True Plug-&-Play Design: Plugs directly into your factory audio wiring harnesses for a quick, clean installation. Only the RGB lighting wires need to be run, saving you hours of splicing.
• Smart System Design: This kit is engineered to retain your factory-installed front subwoofer, recognizing that replacing it on factory power simply adds extra cost without improving real-world performance.
• Limited Lifetime Warranty: Built to withstand the mud, dust, washdowns, and harsh vibrations of aggressive riding, this entire kit is backed by a limited lifetime warranty so you can ride with ultimate peace of mind.

Stop leaving free wattage on the table. Upgrade to the SSV Works 11-Speaker Kit and turn your Polaris RZR Pro R 4 Ultimate into the ultimate mobile soundtrack!
