Rockford Fosgate RFK-HDRKM5 Amplifier Install Kit for Select 1998+ Harley Davidson Road King Motorcycles (Gen 2)

If you ride a 1998 or newer Harley-Davidson Road King and crave concert-quality sound while tearing down the open road, the Rockford Fosgate RFK-HDRKM5 is your ticket to a premium audio experience. This all-in-one amplifier install kit is built specifically for your bike, packing everything you need into a clean, plug-and-play package that takes your factory audio system from flat to phenomenal.

Plug-and-Play Simplicity Meets Pro-Level Sound

Let’s face it — wiring up a sound system can be a pain. But with the RFK-HDRKM5, installation is as close to effortless as it gets. Designed with a true plug-and-play philosophy, this kit includes pre-configured harnesses that snap into place without guesswork or wire splicing. You’ll spend less time elbow-deep in the garage and more time soaking up your favorite playlists on the highway. It even includes detailed drill templates and every screw, clamp, and cable tie you’ll need — all right in the box.

Engineered for the Open Road

Rain, heat, road grime, and vibration — your Harley faces it all. That’s why the RFK-HDRKM5 is Element Ready™, meaning it’s purpose-built to survive the most brutal riding conditions. Whether you’re blasting through a summer thunderstorm or carving curves under the desert sun, this system is tough enough to keep the music pumping mile after mile.

All-In-One Kit for a Clean Custom Upgrade

Forget juggling part numbers and trying to match third-party components. This kit has everything dialed in from the start:

• Bluetooth Streaming Receiver (RFBTRCA) with single-button pairing
• Amp Mounting Plate and Cover to keep things secure and protected
• Plug-and-Play Wiring Harnesses with lower expansion pigtail
• Drill Templates for 1998–2013 and 2014+ Road King models
• All necessary mounting hardware, including drill bits, cable clamps, and zip ties

Whether your bike is a classic cruiser from the early 2000s or a newer ride, Rockford’s got you covered. Just pair this kit with the M5-800X4 amplifier (sold separately) and the appropriate 6x9” saddlebag kit for your year — TMS69BL9813 for 1998–2013, or TMS69BL14 for 2014+ — and you’re ready to rock.

Amplifier Compatibility That Packs a Punch

When paired with the M5-800X4, the RFK-HDRKM5 ensures optimal power delivery, crystal-clear sound, and rock-solid performance. Every cable in the kit is made from 100% Pure Crystal-Oxygen Free Copper (PC-OFC), which means less resistance, more efficiency, and no cutting corners. The kit uses CEA-2015 compliant wiring, guaranteeing the right amount of copper where it counts — unlike cheap knockoffs with oversized plastic insulation.

With 8 AWG power and ground cables, a 60 Amp MAXI fuse, and 16 AWG speaker wire, this setup is built for serious performance without overkill. Think of it as the perfect balance between muscle and finesse — like riding a Road King in sixth gear with the throttle wide open.

Bluetooth Control Right at Your Fingertips

Music should be easy to access, and with the included Bluetooth streaming receiver, it is. Just tap the activation button mounted near your handlebars and pair your device in seconds — no app, no fuss. Whether you're riding solo or two-up, your tunes are always within reach. (Just keep in mind, this is for music streaming only — phone calls stay off the playlist.)

Tailored Fit for Road King Riders

Unlike generic audio kits that require endless mods and custom brackets, the RFK-HDRKM5 is tailor-made for Harley-Davidson Road King motorcycles. Every piece is shaped to fit seamlessly with your bike’s existing layout, so there’s no awkward mounting or wasted space in your saddlebags. From the amp cover to the power wire harnesses, this kit was crafted to blend in and boost performance without sacrificing storage or style.

So, whether you're cruising the city or chasing horizons across the country, this kit delivers the soundtrack your journey deserves. Clean wiring. Rugged build. Killer sound. What else could you want?
