The Rockford Fosgate MX-RSW16 is a rear speaker add-on harness designed to expand compatible UTV audio systems with rear moto-can speakers. It provides the vehicle-specific wiring connections needed to integrate a rear speaker pair without modifying the vehicle harness. It is intended for select Polaris RZR, Can-Am Maverick X3, and Polaris Ranger audio applications; fitment should be verified before purchase.
This harness is for riders building a more complete sound field in two-seat or four-seat UTVs. By supporting rear speaker placement, it helps extend audio coverage to passengers and rear seating areas when used in a compatible Rockford Fosgate system. It is a wiring accessory only and does not include speakers, an amplifier, or a source unit.
The MX-RSW16 does not create sound on its own; final output, volume, and tonal character depend on the compatible moto-can speakers and amplifier used with it. It is designed for Rockford Fosgate M0WL-65MB, M1WL-65MB, and M2WL-65MB moto-can speaker applications. This makes it a practical expansion component for a system already built around compatible Rockford Fosgate equipment.
Its plug-and-play layout is engineered to connect rear speakers through the appropriate vehicle-specific amplifier installation kit. The harness package includes dedicated 16 AWG speaker-wire harnesses plus an 18 AWG RGW wire harness for the installation. This integrated approach helps avoid splicing into the vehicle wiring when installed in a supported application.
The MX-RSW16 fits into an upgrade path for adding rear moto-cans after a compatible UTV audio system has been installed. It requires a matching RZR14, X317, or RNGR18 amplifier wiring kit, depending on the vehicle platform. For Color Optix-equipped speaker setups, it supports the wiring needs of compatible Color Optix moto-can models while keeping the installation organized.
Key Features
- Rear Speaker Expansion: Adds wiring capability for rear moto-can speakers in select UTV audio systems.
- Plug-And-Play Connections: Designed to install without cutting or drilling the vehicle.

- UTV Platform Support: Made for select RZR, Maverick X3, and Ranger applications.
- Two- And Four-Seat Use: Designed for compatible two-seat and four-seat UTV models.
- Included Harness Components: Includes speaker, RGW, and zip-tie installation hardware.
Design & Installation
The MX-RSW16 is a purpose-built wiring accessory rather than a speaker or amplifier. Its harness-based design uses 16 AWG speaker wiring and an 18 AWG RGW harness to support rear-speaker integration in compatible Rockford Fosgate UTV systems. The package also includes eight zip ties to help secure the wiring during installation.
Use this harness only with a verified compatible vehicle and the required platform-specific amplifier wiring kit: RZR14-K4, RZR14-K8, X317-K4, X317-K8, RNGR18-K4, or RNGR18-K8. Pair it with compatible M0WL-65MB, M1WL-65MB, or M2WL-65MB moto-can speakers, which are sold separately. Review the manufacturer compatibility chart and follow the applicable installation instructions before routing or connecting the harness.
