Rockford Fosgate RFYXZ-K8 Yamaha YXZ Amp Kit and Mounting Plate

The Rockford Fosgate RFYXZ-K8 is a vehicle-specific amplifier installation kit for select Yamaha YXZ side-by-side models. It combines an amplifier mounting plate with a preconfigured wiring harness to simplify adding a compatible Rockford Fosgate compact amplifier. It is intended for riders building or expanding a Rockford Fosgate YXZ audio system.

This kit addresses the extra fabrication and wiring work normally involved in a UTV amplifier upgrade. Its mounting plate uses the vehicle's OEM mounting locations, eliminating the need to drill mounting holes. Pre-cut, loomed power, ground, and speaker wiring helps create a cleaner installation with less custom wire routing.

The RFYXZ-K8 is designed for use with Rockford Fosgate Power T400X4ad and TM400X4ad small-chassis amplifiers, sold separately. Those compatible amplifiers provide the power stage for speaker-based YXZ audio systems, while this kit supplies the vehicle-specific mounting and connection foundation. The kit supports one amplifier installation.

Its plug-and-play harness is made for Rockford Fosgate YXZ-specific audio components, helping integrate compatible speakers, enclosures, and system accessories. The included inline 60-amp MAXI fuse holder provides circuit protection for the amplifier power connection. This makes the kit a practical starting point for a coordinated, vehicle-specific system build.

For Yamaha YXZ owners who want an organized amplifier installation rather than a universal wiring approach, the RFYXZ-K8 keeps the installation focused on fitment and serviceability. The included hardware and wire ties support secure mounting and harness management. Confirm vehicle and amplifier compatibility before installation, especially when combining this kit with additional audio components.

Design & Installation

The RFYXZ-K8 combines a dedicated amplifier mounting bracket with a vehicle-oriented wire harness and installation hardware. Its pre-cut, loomed wiring is arranged to reduce exposed loose wire and support a more orderly installation. The mounting plate is designed around the Yamaha YXZ factory mounting locations.

Install the kit with a compatible T400X4ad or TM400X4ad amplifier, which is not included. Route and secure the harness carefully, use the included wire ties where appropriate, and connect it only with compatible Rockford Fosgate YXZ-specific audio components. Verify the exact vehicle fitment and follow the supplied installation instructions before disassembly or wiring work.
