SSV Works Plug-&-Play Rear-Seat 10in Subwoofer Add-On for 2026-2027 Polaris RZR Pro R 4, 2027 Pro S 4 & Pro XP 4 with Factory Rockford Fosgate Audio

Double the powered bass in your 4-seat RZR Pro using the factory Rockford Fosgate amp. This SSV Works rear-seat enclosure plugs into the factory rear subwoofer output that Polaris already runs to the back, adding a second sub on the amp's second sub channel.

• Adds a second subwoofer at 400 watts at 4 ohms on the factory amp's second sub channel, for double the powered sub output of the single factory sub
• Drops into the cavity under the rear driver-side seat and plugs into the factory harness already at that location
• No amp replacement, no cutting, no custom brackets and no wire routing; SSV calls it a 20-minute install
• Kicker Comp RT 10" 4-ohm subwoofer rated up to 800 watts max with 85 dB sensitivity
• Keeps the factory amp, factory integration and factory functionality intact

Requires factory Rockford Fosgate audio. This kit uses the factory amplifier and wiring harness, so it only fits trims that came with factory audio from Polaris. Sport and Premium trims and 2-seat models are not compatible.

Fits: 4-seat 2026-2027 Polaris RZR Pro R 4 Ultimate, 2027 Pro R 4 Boost Ultimate and Ultra, 2027 Pro XP 4 Ultimate and 2027 Pro S 4 Ultimate. Exact vehicle fitment is listed in the Vehicle Fitment section.
