Rockford Fosgate YXZ-STAGE3 Yamaha YXZ 6.5"/10" Audio Kit

The Rockford Fosgate YXZ-STAGE3 is a vehicle-specific amplified audio package for select Yamaha YXZ side-by-side models. It combines a compact digital media receiver, a pair of 6.5-inch front speakers, a 400-watt four-channel amplifier, and a 10-inch subwoofer in a dedicated enclosure. The package is intended to add full-range sound and bass while retaining a clean, integrated installation.

This kit is designed for Yamaha YXZ owners who want a coordinated audio upgrade rather than sourcing separate receiver, speaker, amplifier, enclosure, and wiring components. Direct-connect harnesses and model-specific mounting parts help simplify system integration. Fitment should still be verified for the exact vehicle configuration before purchase.

The RM1652B 6.5-inch marine speakers cover the front-stage frequencies, while the RM110D2B 10-inch dual-2-ohm subwoofer extends low-frequency output. The amplifier provides dedicated channels for the system and supports separate high-pass and low-pass crossover settings. This arrangement helps keep bass duties with the subwoofer while allowing the front speakers to focus on midrange and high-frequency playback.

At the center of the system is the PMX-2 compact marine digital media receiver with Bluetooth audio streaming, AM/FM/weather-band reception, rear USB and auxiliary inputs, and a 2.7-inch color TFT display. The included TM400X4ad Class-AD amplifier uses selectable crossover filters, adjustable Punch EQ, and a compact chassis. Element Ready construction is intended for exposure common to off-road powersports use.

The YXZ-STAGE3 builds on the brand's Stage 2-style receiver and front-speaker foundation by adding amplification, an amplifier installation kit, and a loaded subwoofer enclosure. Its four-channel amplifier can be configured with the front channels for the speakers and bridged rear channels for the subwoofer. The complete approach suits riders seeking an integrated Yamaha YXZ audio system with Bluetooth playback and added low-end support.

Design & Installation

The system uses vehicle-specific speaker and subwoofer enclosures, a dedicated dash installation kit, and a compact marine-rated amplifier platform. The RM1652B speakers use marine-grade construction, while the included amplifier is designed with a coated circuit board, dual cooling fans, and extruded heat sinks. The PMX-2 receiver provides a color display and large physical controls suited to an off-road cockpit.

Installation uses the supplied RFYXZ-PMXDK dash kit, RFYXZ-FSE front speaker enclosures, RFYXZ-FWE subwoofer enclosure, RFYXZ-K8 amplifier wiring kit, and direct-connect harnesses. Rockford Fosgate's installation guidance specifies setting the front channels to an 80 Hz high-pass crossover and rear channels to an 80 Hz low-pass crossover as a starting point. Disconnect the vehicle battery before wiring, secure all wiring away from moving parts and sharp edges, and verify exact vehicle fitment; an antenna is not included.
