UTV Stereo Polaris RZR Pro Signature Stage 8 Stereo Kit (2025-2026)

The UTV Stereo Signature Series Stage 8 is a complete RZR Pro R sound system for the 2025-2026 Polaris RZR Pro R, Pro XP and Pro S, running 2,600 watts through three Signature Series amplifiers. Four Pro Series 6.5” speakers, an Elite 12” subwoofer in a vented dash enclosure, a bass knob and a Wet Sounds MC-20 head unit are included.

UTV Stereo describes the kit as delivering 2,600 watts of dune-shaking power and higher-than-high fidelity sound. It is the top Signature Series stage for the 2025-2026 RZR Pro Series, and because the head unit is included it works as a complete RZR radio system and Pro XP stereo upgrade for riders without RIDE COMMAND.

Built To Solve: Weak Factory Audio In The 2025-2026 Polaris RZR Pro R

• No dedicated subwoofer or bass control in the cab
• Piecing together amps, speakers and a head unit that were not designed as one system
• Speakers that run out of power when the volume goes up

Does this kit include compression horns, tweeters or RGB rings?

No. Horns, tweeters and RGB LED rings are not on UTV Stereo's included-parts list for this kit. The 2025-2026 Elite Stage 6 lists 8” compression horns with RGB rings.

Does this kit work with Polaris RIDE COMMAND?

No. UTV Stereo states this kit is not compatible with RIDE COMMAND. It uses the Wet Sounds MC-20 head unit included in the kit. If your 2025-2026 RZR Pro Series has RIDE COMMAND, choose a UTV Stereo 2025+ Ride Command stage kit instead.

Which 2025-2026 RZR Pro models does this kit fit, and why is the 2026 Pro R a separate option?

UTV Stereo lists the Polaris RZR Pro XP, Pro R and Pro S for 2025-2026. The 2026 Pro R is sold as its own vehicle selection with its own part number, so pick the option that matches your exact year and model. It is not listed for the 2020-2024 Pro Series.

Do the product photos show only what is in the box?

No. UTV Stereo's photos also show items sold separately, such as rear seat subwoofer upgrade parts and speaker enclosures. The included-parts list in the first FAQ answer is what ships with the kit.

How does the Signature Stage 8 compare to the 2025-2026 Elite Stage 6?

The Signature Stage 8 runs three Signature amps for 2,600 watts through four 6.5” speakers and the 12” sub. The Elite Stage 6 runs one Elite 1600W 5-channel amp through two 6.5” speakers, two 8” horns with RGB rings and the 12” sub.

Why UTV Stereo

UTV Stereo builds vehicle-specific stage kits for side-by-sides, matching its Pro, Signature and Elite Series speakers and amplifiers with dash subwoofer enclosures made for the machine. The 2025-2026 RZR Pro Series kits are built around the redesigned Pro Series cab, so the 12” vented dash enclosure and component layout are specific to these machines.

Complete Your 2025-2026 RZR Pro Signature Stage 8 Stereo

Before ordering this 2025-2026 RZR Pro Signature Stage 8 stereo kit, confirm your machine is a Pro R, Pro XP or Pro S without RIDE COMMAND and select the matching vehicle option, since the 2026 Pro R has its own version. A three-amplifier system draws real current, so many owners add a second battery kit, and UTV Stereo's 2025+ subwoofer kits add more bass.
