Rockford Fosgate RZR14-STG4 RZR Kit with 6.5" Speakers & 10" Sub

The Rockford Fosgate RZR14-STG4 is a complete Stage 4 audio upgrade package for select 2014–2021 Polaris RZR models. It replaces the need to source a receiver, amplifier, speakers, subwoofer, enclosures, wiring, and lighting controller separately. The system is designed for RZR owners who want a coordinated, vehicle-specific audio installation with front and rear sound coverage.

At its center is the PMX-2 compact digital media receiver, which adds Bluetooth audio streaming, USB and auxiliary inputs, plus AM/FM/weather-band radio. Its 2.7-inch color TFT display is integrated through the included RZR14-DK dash kit. The receiver provides source control while the external amplifier supplies the primary system power.

The kit uses a pair of 6.5-inch M1-65B Color Optix coaxial speakers in RZR14-FSE front enclosures and a pair of 6.5-inch M1WL-65MB Color Optix Moto-Cans for rear placement. This layout places full-range sound at both the front and rear of the cabin. The speaker system uses RGB illumination controlled by the included PMX-RGB Color Optix controller.

Low-frequency output comes from the included 10-inch M1D2-10B dual-voice-coil Color Optix subwoofer installed in the RZR14-FWE direct-fit vented enclosure. The M5-800X4 four-channel Element Ready amplifier provides 100 watts RMS per channel at either 2 or 4 ohms, with preset tuning support for compatible Rockford Fosgate UTV systems. Its crossover controls and compact chassis help it serve as the power foundation for this vehicle-specific package.

RZR14-STG4 is intended as a coordinated upgrade rather than a universal car-audio bundle. It includes the purpose-built mounting components and harnessing required by the kit design, helping retain cabin space while adding receiver, amplified speakers, bass, and configurable lighting. Confirm vehicle fitment before purchase, particularly if the RZR is equipped with Ride Command, which uses a different system configuration.

Design & Installation

This package combines vehicle-specific enclosures, a custom dash kit, and Element Ready audio components made for exposed powersports use. The M1 speakers use mineral-filled polypropylene cones, Santoprene surrounds, and UV-stable lighting components, while the M5-800X4 amplifier has an IPX6-rated Element Ready construction. The front enclosures and vented subwoofer enclosure are shaped for the applicable RZR platform rather than being generic speaker boxes.

Install the system only after confirming the exact RZR year, trim, and factory-equipment compatibility. The included RZR14-DK, RZR14-FSE, RZR14-FWE, and RZR14-K8 components are intended to support the receiver, front speakers, subwoofer, amplifier, and wiring installation; follow the supplied vehicle-specific instructions and amplifier preset guidance. The PMX-RGB controller is used with the RF Connect app for Color Optix lighting adjustment.
