Rockford Fosgate HD9813RG-STG2 6.5" Road Glide Audio Kit

The Rockford Fosgate HD9813RG-STG2 is a Stage 2 motorcycle audio upgrade for select 1998-2013 Harley-Davidson Road Glide models. It combines a pair of direct-fit 6.5-inch fairing speakers, a four-channel M5-800X4 amplifier, and a vehicle-specific amplifier installation kit. The system is intended for riders who want a substantial powered audio upgrade while retaining a factory-fit approach.

The included TMS6RG speakers use a 2-way coaxial design with a 25 mm film-dome tweeter and integrated phase plug. Their carbon-fiber-reinforced polypropylene cones and Santoprene components are designed for outdoor motorcycle use. The speaker design is tuned to provide clear midrange and high-frequency reproduction in a fairing location.

Power comes from the included M5-800X4 four-channel Class-AD amplifier. It provides 100 watts RMS per channel at either 4 or 2 ohms, with two additional channels available for compatible future speaker expansion. High-pass, low-pass, and all-pass crossover settings allow the amplifier to be configured for the installed system.

The HD9813RG-STG2 is built around Rockford Fosgate's Element Ready design approach for exposure to water, dust, UV, corrosion, temperature changes, and vibration. The amplifier carries an IPX6 water-intrusion rating, while the fairing speakers use weather-resistant materials and grilles. This makes the kit appropriate for motorcycles regularly used in changing outdoor conditions.

The supplied RFK-HD9813M5 installation kit is designed for select 1998-2013 Harley-Davidson Touring applications and includes the amplifier mounting and connection hardware needed for this package. It uses direct-connect harnessing and factory attachment points to simplify integration. Y-adapters in the install kit support expansion to compatible lower-fairing, saddlebag, or Tour-Pak speaker additions.

Key Features

• Road Glide-Specific Fit: Designed for select 1998-2013 Road Glide fairings, including 2012 Road Glide Custom fitment.
• 6.5-Inch Coaxial Speakers: TMS6RG speakers pair full-range woofers with integrated 25 mm film-dome tweeters.
• M5-800X4 Amplifier: Four-channel Class-AD amplifier supplies continuous power for the front speakers and future expansion.
• Element Ready Construction: Components are engineered for motorcycle exposure to weather, UV, vibration, and corrosion.
• IPX6 Amplifier Protection: The amplifier is rated to resist powerful water jets from any direction.
• Expansion-Ready Wiring: Included Y-adapters support compatible lower, saddlebag, or Tour-Pak speaker additions.

Design & Installation

The TMS6RG speakers use carbon-fiber-reinforced polypropylene cones, Santoprene VAST surrounds, Santoprene front isolation spiders, neodymium motor structures, and glass-reinforced polymer frames. New Road Glide grille assemblies are included. The M5-800X4 uses an Element Ready chassis, conformal-coated circuit boards, molded wiring connections, and a covered top control panel.

This kit is designed to mount at factory attachment points with direct-connect harnessing on compatible motorcycles, without drilling or cutting. Verify motorcycle fitment before purchase, particularly the fairing style and model year. Install the amplifier power wiring with the specified fuse protection and configure its crossover and input settings for the connected speakers.
