Polaris RZR Pro R 4 Ultimate (2026) Plug-&-Play Rear-Seat 10" Subwoofer

The 2026 RZR Pro R factory Rockford Fosgate system runs a single factory subwoofer with 400 watts at 4 ohms from a dedicated sub channel. This SSV Works rear-seat subwoofer enclosure plugs into the factory rear subwoofer output that is already run to the back, adding a second subwoofer on the amp’s second sub channel, also delivering 400 watts at 4 ohms. The result is double the powered sub output versus the single factory sub setup, with no amp replacement and no wiring required.

This enclosure is designed specifically for the 2026 Polaris RZR Pro R 4 and drops directly into the cavity under the rear driver-side seat. The best part, Polaris already runs the rear subwoofer output harness to that location from the factory, so installation is as simple as setting the enclosure in place and plugging it in. No cutting, no custom brackets, no wire routing. It is a true 20-minute install.

Loaded with an SSV 10" 4-OHM subwoofer rated for up to 1000 watts max, with 85 dB sensitivity and a 40 Hz–1.5 kHz frequency response. Built for the UTV world, it’s designed to take real vibration and punishment while delivering tight, hard-hitting bass that keeps up at speed.

Every 2026 RZR Pro R comes equipped with factory Rockford Fosgate audio, which makes this the ideal next-step upgrade for owners who want more bass without rebuilding the system. This enclosure is tuned and fit for the Pro R 4 platform, adding serious low-end performance while keeping the factory amp, factory integration, and factory functionality intact. It is the cleanest way to get a major bass upgrade from the system you already have.

We back what we build with coverage no other powersports audio brands come close to. This enclosure and the SSV subwoofer are protected by our Limited Lifetime Warranty, so your bass upgrade is covered for the long haul.
