It provides the mounting hardware, heat sink, wiring harnesses, and connection accessories needed to add a compatible Rockford Fosgate amplifier without building an installation from individual parts. The amplifier is sold separately.\u003c\/p\u003e\u003cp\u003eThis kit is intended for riders upgrading a factory or compatible motorcycle audio system with amplified front and rear speaker capability. Its vehicle-specific harnessing and included fairing brackets help organize the installation around the motorcycle's existing layout. It is designed for applicable Road Glide, Street Glide, and Electra Glide models.\u003c\/p\u003e\u003cp\u003eThe RFK-HD9813M5 does not create sound on its own; it supports a system upgrade by providing the infrastructure for a compatible four-channel amplifier. It is compatible with the Rockford Fosgate M5-800X4 and TM400X4ad amplifiers. This makes it a practical foundation for a higher-output speaker system when paired with the appropriate amplifier and speakers.\u003c\/p\u003e\u003cp\u003eFull-spec, pure crystal oxygen-free copper wiring is used to meet or exceed American Wire Gauge requirements. The kit also includes an amplifier heat sink and motorcycle-specific mounting hardware for Bat Wing and Shark Nose fairing applications. These components help create a cleaner, purpose-built installation than adapting universal hardware.\u003c\/p\u003e\u003cp\u003eExpansion provisions are included for riders planning more than a basic front-speaker upgrade. The supplied speaker-output Y-adapters support lower-fairing, saddlebag, or Tour-Pak speaker expansion, while rear speaker harnesses are included for rear-speaker connections. This allows the kit to serve as part of a staged audio upgrade path.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVehicle-Specific Fit:\u003c\/strong\u003e Designed for select 1998-2013 Harley-Davidson touring motorcycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Amplifiers:\u003c\/strong\u003e Supports M5-800X4 and TM400X4ad four-channel amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-and-Play Harnessing:\u003c\/strong\u003e Helps simplify amplifier integration with motorcycle-specific connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFairing Mounting Hardware:\u003c\/strong\u003e Includes brackets for Bat Wing and Shark Nose fairings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Expansion:\u003c\/strong\u003e Y-adapters support additional lower, saddlebag, or Tour-Pak speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Speaker Provision:\u003c\/strong\u003e Includes rear speaker output harnesses for expanded systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe RFK-HD9813M5 combines full-spec PC-OFC cable, dedicated amplifier mounting brackets, threaded studs, mounting screws, harnesses, cable ties, and an amplifier heat sink.
