Rockford Fosgate X3-Stage4 400W Stereo, Front, Rear & Subwoofer Kit

Our review of the Rockford Fosgate X3-Stage4 kit finds it aimed at Maverick X3 owners who want a complete, vehicle-specific audio upgrade that installs cleanly and holds up to outdoor use. The bottom line: this package delivers a full stereo, front and rear speakers, a compact PMX-2 digital media receiver, and a powered 10' subwoofer enclosure that integrate without sacrificing passenger or cargo space, making it the best one-stop solution for trail riders who value convenience and durable, element-ready sound.

Key Features

• Direct connect wiring harnesses: The kit includes model-specific harnesses for Maverick X3 models so installation is faster and avoids cutting factory wiring.
• Element Ready design: All components are built to resist dust, moisture and UV exposure so the system survives harsh off-road conditions.
• Space-saving enclosures: Front and subwoofer enclosures integrate with the vehicle structure to preserve passenger and cargo room.
• PMX-2 compact receiver: The PMX-2 Punch Marine receiver with a 2.7' display provides AM/FM/WB and digital media control in a compact dash kit designed for the Maverick.
• Full speaker complement: Includes RM1652B 6.5' full-range speakers and an RM110D2B 10' dual 2-ohm subwoofer for a balanced, full-band listening experience.
• Model-specific dash and enclosures: Dash kit and front/rear enclosures (RFX3 series) are tailored to the Maverick X3 line to ensure fit and finish.

Who It's For

This kit is best for Can-Am Maverick X3 owners (2017-2018 Turbo and Turbo R variants, including MAX and X DS/RS trims) who want a factory-integrated audio solution that withstands dunes, mud and sun without compromising interior space. It suits riders who prefer a single bundled purchase that includes receiver, harnesses, and matched speakers and sub.

It is less suitable for owners of non-listed model years or other UTV brands, or for buyers who want a fully custom-sourced audio build with different speaker sizes or brands; those users should consider separate component selection and custom installation options.
