Rockford Fosgate HD9813SG-PMX-STG2 6.5" Harley Audio Kit

The Rockford Fosgate HD9813SG-PMX-STG2 is a Stage 2 motorcycle audio package for select 1998-2013 Harley-Davidson Electra Glide and 2006-2013 Street Glide models. It combines a direct-replacement digital media receiver, two fairing speakers, a four-channel amplifier, and a model-specific installation kit. The system is intended to replace the factory source unit while adding amplified front-fairing sound.

This package suits riders who want a coordinated upgrade rather than sourcing a radio, speakers, amplifier, and wiring separately. The included PMX-HD9813 receiver uses OEM-style electrical connections and retains factory thumb controls when installed on compatible motorcycles. Its digital-media design adds Bluetooth audio streaming, USB playback and charging, AM/FM reception, auxiliary input, Pandora control, and SiriusXM readiness with a separately purchased tuner.

Two TMS6SG 6.5-inch, two-way fairing speakers handle the front-stage audio. Each speaker is rated for 75 watts RMS and uses a 25 mm film-dome tweeter with a phase plug, a carbon-fiber-reinforced polypropylene cone, and a Santoprene surround. Their motorcycle-specific design focuses on maintaining clear output in the presence of wind, road, and engine noise.

Power comes from the included M5-800X4 four-channel Element Ready amplifier. It provides 100 watts RMS per channel at either 2 or 4 ohms, with higher CTA-2006 dynamic-power ratings available for musical peaks. Its Class AD design, weather-resistant construction, and adjustable crossover sections make it suitable for a fairing-mounted motorcycle audio system.

The RFK-HD9813M5 installation kit supplies model-specific wiring and hardware for the amplifier installation. The harness arrangement includes Y-adapters that can support later speaker expansion in compatible lower fairing, saddlebag, or Tour-Pak locations. Verify the motorcycle's exact year, trim, factory equipment, and compatibility before purchase, particularly where factory amplification, CB, intercom, rear controls, or factory satellite-radio equipment is present.

Design & Installation

The components are purpose-built for motorcycle use. The M5-800X4 amplifier carries an IPX6 water-intrusion rating, while the speakers use durable materials including a carbon-fiber-reinforced polypropylene cone, Santoprene surround, polymer frame, and neodymium motor structure. The PMX-HD9813 features a 3-inch color TFT display, day/night display modes, oversized controls, and 4-volt preamp outputs.

Installation is designed around compatible factory attachment points and direct-connect harnesses, with no cutting or drilling specified for standard compatible applications. The PMX-HD9813 requires the factory wiring harness and connectors to retain intended plug-and-play functionality; systems needing rear speaker-line outputs require the applicable added harness. For proper setup, follow the supplied tuning guidance, use the correct fuse protection, and confirm that the motorcycle does not have incompatible factory amplified, CB, intercom, rear-volume, rear-speaker, or factory satellite-radio equipment.
