Rockford Fosgate Rear Subwoofer Solution – Polaris RZR Pro XP 4 (2019–2024)

Take your Polaris RZR Pro XP 4 (2019–2024) audio system to the next level with the Rockford Fosgate RZR19PXP-RSS Rear Subwoofer Solution. Designed to integrate seamlessly with existing Rockford Fosgate Stage 4, 5, or 6 audio systems, this upgrade adds a secondary 10” M2 Element Ready™ subwoofer that delivers chest-thumping low-end performance on every ride.

The vented enclosure is optimized for maximum bass output but includes an optional sealing cap for water submersion or when tighter bass response is preferred. Built with Element Ready™ technology, the enclosure resists water, UV rays, dust, and mud—ensuring reliability no matter the terrain.

Engineered for a plug-and-play install, the rear subwoofer solution bolts directly to OEM mounting points with no cutting or drilling required. With its factory-fit finish, the system looks like it came installed from the factory, all while unleashing 600 watts of bass power.
