// FULL-AMPLIFIER PERFORMANCE
UNLOCK THE POWER POLARIS LEFT ON THE TABLE.
UNLOCK THE POWER POLARIS LEFT ON THE TABLE.
Built exclusively for the 2026 Polaris RZR Pro R 4 Ultimate, UNPHASED-7 is designed around the factory 10-inch Ride Command system and 1500-watt, 8-channel amplifier. The big wattage number sounds impressive, but the factory setup only uses about half of that available power. With an unused second subwoofer channel, no front door speakers and cheap speakers from the factory, a large portion of the amp goes untouched. UNPHASED-7 changes that by upgrading the speakers and putting the factory amp to work the way it should have been from day one. The result is more output, fuller sound, and stronger bass, without the added cost of an aftermarket amplifier.
// FACTORY-INTEGRATED INSTALL
BOLT DOWN. PLUG IN. TURN IT UP.
This kit is built to integrate cleanly with the vehicle using the factory audio wiring harnesses, keeping installation simple and efficient. No major audio wiring needs to be run, only the RGB harness. The kit includes eleven speakers total, with two tweeters, eight 6.5" full-range powersports speakers, and one 10in subwoofer. Engineered for off-road use, these speakers deliver greater clarity, stronger midbass, no distortion and overall more output than the factory speakers, transforming the sound.
// AMPLIFIED LOW-END ADVANTAGE
DOUBLE THE BASS, NO WASTING MONEY.
The included rear seat 10-inch subwoofer enclosure plugs into the factory system and uses the amp’s unused second subwoofer channel. Since each sub channel delivers 400 watts at 4 ohms, adding this enclosure brings an additional 400 watts into play, effectively doubling the vehicle’s subwoofer power compared to the factory setup. The front factory subwoofer stays in place for a reason. Replacing it with a higher-power aftermarket sub would still leave it receiving the same 400 watts, delivering little to no real benefit while increasing cost. This kit is built to improve performance where it matters, not sell parts you do not need.
