Fitment Note:
This amplifier is not for individual sale and can only be purchased with the HD24-STG2 or HD24-STG3 Kits. 2023.5+ Harley-Davidson models must have the latest factory software installed before adding the TMA-1000X4i amplifier. The amplifier will also need to be updated and tuned.
If you’re unsure, reach out. We deal with this every day.

Overview

The Rockford Fosgate RFK-HD24 is the backbone of a proper amplifier install on 2024+ Harley touring bikes.

If you’re adding a TMA-1000X4i amplifier, this is the kit that makes it all work the way it should. It gives you a clean, plug and play connection to the factory system without cutting or hacking into wiring.

This is the same setup used in the HD24 Stage kits, and it’s built specifically for the new Skyline OS platform.

What You’re Getting

This is a complete amplifier installation kit designed for 2024+ Street Glide and Road Glide models.

You’re getting:

• Model-specific amplifier mounting plate
• Complete plug and play wiring harness
• Power and ground harness
• Skyline OS interface connection
• All required mounting hardware

Everything is designed to work together for a clean, factory-style install.

How It Performs

This kit doesn’t change the sound on its own, but it’s what allows your amplifier to perform the way it should.

You get a solid electrical foundation, proper signal integration, and a clean path from the amp to your speakers.

Installation

This kit is built as a true plug and play solution using factory-style connectors.

It connects directly into the bike’s A2B system and routes amplifier output through the factory speaker wiring. No radio flashing is required.

The mounting plate is designed to fit both Street Glide and Road Glide models and keeps the amplifier mounted securely in the correct location.

Built for Real Use

Everything in this kit is designed for the environment these bikes live in. The wiring is protected, connections are sealed, and the materials are built to handle heat, vibration, and weather.
