Rockford Fosgate MX-RSW16 Rear Color Optix Speaker Add-On Harness

The Rockford Fosgate MX-RSW16 is a rear speaker add-on harness designed to expand select UTV audio systems with rear-mounted moto-can speakers. It provides the wiring needed to integrate compatible rear speakers into supported Rockford Fosgate RZR, Can-Am Maverick X3, and Ranger system applications. This harness is intended for riders who want to extend audio coverage to rear-seat passengers or add rear sound to an existing compatible system.

Rather than being a speaker, amplifier, or source unit, the MX-RSW16 is a vehicle-specific system-expansion component. It supports a cleaner rear-speaker installation by connecting compatible moto-can speakers to the appropriate Rockford Fosgate amplifier wiring kit. Audio output and sound character are determined by the separately purchased speakers and amplifier used with the harness.

The harness is designed for use with Rockford Fosgate M0WL-65MB, M1WL-65MB, and M2WL-65MB moto-can speakers. These compatible speaker options allow the harness to serve as part of an Element Ready or Color Optix-equipped UTV audio upgrade. It is suitable for supported two-seat and four-seat vehicle applications.

Rockford Fosgate uses a plug-and-play approach for this add-on harness to reduce the need for custom wiring work. The installation is designed to avoid cutting or drilling the vehicle when used in an approved application. This helps maintain a more organized installation while simplifying future service or system changes.

The MX-RSW16 fits into a staged Rockford Fosgate UTV audio system when rear moto-can speakers are being added after the primary amplifier wiring is in place. It requires a compatible RZR14, X317, or RNGR18 amplifier installation kit, sold separately. Verify the vehicle-specific compatibility chart before purchase, since fitment depends on the UTV model and installed audio-system components.

Design & Installation

The MX-RSW16 is a purpose-built harness package for Rockford Fosgate UTV audio-system expansion rather than a universal speaker-wire kit. Its included harnesses use 16 AWG speaker wiring and an 18 AWG RGB wiring harness for supported Color Optix-related installations. The package also includes zip ties to help secure the harness during installation.

For installation, pair the MX-RSW16 with compatible M0WL-65MB, M1WL-65MB, or M2WL-65MB moto-can speakers and the correct separately sold amplifier installation kit for the vehicle platform. Supported amplifier-kit families include RZR14, X317, and RNGR18 applications; exact kit selection and vehicle fitment should be confirmed before ordering. Follow the applicable Rockford Fosgate installation guidance and route wiring securely away from moving parts, heat, and pinch points.
