Rockford Fosgate HD14-PMX-STG3 6.5/6x9 Harley Audio System

The Rockford Fosgate HD14-PMX-STG3 is a complete Stage-3 motorcycle audio upgrade for select 2014-2023 Harley-Davidson Street Glide and Road Glide models. It combines a direct-replacement PMX-HD14 infotainment receiver, front fairing speakers, rear saddlebag speakers, a four-channel amplifier, and a vehicle-specific installation kit. The package is intended for riders who want a coordinated audio system rather than sourcing individual components separately.

The system uses two 6.5-inch TMS65 fairing speakers and two 6x9-inch TMS69BL14 saddlebag speakers to create front and rear coverage. Its M5-800X4 amplifier provides four amplified channels and the kit is rated at 800 watts total power. This layout is designed to help music remain audible against typical motorcycle wind, road, and exhaust noise.

At the center of the system, the PMX-HD14 replaces the factory radio in compatible Harley-Davidson applications. It provides a 7-inch color TFT touchscreen, Apple CarPlay, Bluetooth audio, AM/FM/weather-band reception, USB playback, and SiriusXM readiness with a compatible tuner and subscription. Factory thumb-control functionality is retained on compatible motorcycles.

The included M5-800X4 amplifier is an IPX6-rated, Element Ready four-channel model with configurable high-pass and low-pass crossovers. The amplifier installation kit uses vehicle-specific wiring, mounting hardware, and an 8 AWG power/ground arrangement to integrate the amplifier with the motorcycle. A 90-degree harness is included for applicable Road Glide installations.

The saddlebag kit is made for factory Harley-Davidson ABS hardshell bags and uses retrofit templates, grilles, wiring, and mounting hardware. The system can also serve as a foundation for a larger Rockford Fosgate Harley-Davidson audio build, with harness provisions that support additional lower-fairing, saddlebag, or Tour-Pak speaker expansion. Verify the manufacturer compatibility chart for the exact motorcycle, trim, factory audio equipment, and saddlebag configuration before purchase.

Design & Installation

The HD14-PMX-STG3 combines purpose-built motorcycle components with factory-oriented fitment. The TMS65 speakers use integrated 25 mm tweeters, while the TMS69BL14 bag-lid speakers use weather-resistant construction, Santoprene VAST surrounds, reinforced polymer frames, and protective grilles. The M5-800X4 uses an Element Ready chassis, conformal-coated circuit boards, heavy-duty connectors, and an IPX6 water-intrusion rating.

Installation uses the supplied RFK-HD14M5 amplifier kit, direct-connect harnesses, mounting brackets, and saddlebag cut-in templates. The base package is designed to eliminate the need to flash the radio, although using front/rear fader functionality requires the specified Rockford Fosgate 2014+ All Bikes flash. Confirm fitment before installation, especially for factory-equipped audio packages, Harley-Davidson ABS saddlebags, and Road Glide versus Street Glide fairing configuration.
