Rockford Fosgate HD14-STG2 6.5" Harley Speaker & Amp Kit

The Rockford Fosgate HD14-STG2 is a Stage-2 motorcycle audio upgrade for select 2014-2023 Harley-Davidson Road Glide and Street Glide models. It combines two direct-fit 6.5-inch fairing speakers, a four-channel amplifier, and a model-specific installation kit. The system is intended for riders who want more usable volume and clarity than the factory fairing speakers can provide on the road.

The kit uses a pair of TMS65 two-way coaxial speakers with integrated 25 mm dome tweeters. Their fairing-focused design helps reproduce vocals, instruments, and high-frequency detail through typical wind, road, and exhaust noise. Each TMS65 speaker is rated for 75 watts RMS and uses a 4-ohm nominal impedance.

Power comes from the included M5-800X4 four-channel, Class-AD amplifier. It is rated at 100 watts RMS per channel at either 2 or 4 ohms, giving the system additional channels for compatible expansion. The amplifier includes adjustable front and rear crossovers, gain controls, clip indicators, and selectable two- or four-channel input operation.

The M5-800X4 has an IPX6 Element Ready design for exposure common to powersports installations. Its conformal-coated circuit boards, molded connectors, and aluminum heat sink are intended for a motorcycle environment. The RFK-HD14M5 installation package provides the mounting hardware, heat sink, T-harness, power wiring, speaker wiring, and adapters needed for the intended application.

This kit is a practical foundation for a Rockford Fosgate Harley-Davidson audio system because its amplifier has two unused channels available for compatible speaker expansion. The included T-harness supports front-to-rear fader operation after the required radio flash. Factory thumb controls are retained when the system is installed and configured as specified.

Key Features

• Stage-2 Harley Audio Kit: Combines speakers, amplification, and vehicle-specific installation hardware.
• Two 6.5-Inch TMS65 Speakers: Direct-fit two-way fairing speakers replace the factory front speakers.
• M5-800X4 Amplifier: Four-channel Class-AD amplifier supports the included speakers and future expansion.
• Element Ready Construction: IPX6 amplifier design helps suit exposed motorcycle installation environments.
• Direct-Connect Harnessing: Included wiring is tailored for compatible Harley-Davidson motorcycle applications.
• Factory Radio Integration: Retains factory thumb controls and supports front-to-rear fading after flashing.

Design & Installation

The HD14-STG2 is built around vehicle-specific components rather than universal speaker adapters. TMS65 speakers use an integrated dome tweeter and built-in tweeter crossover, while the M5-800X4 uses an extruded-aluminum heat sink and heavy-duty molded harness connections. Street Glide, Road Glide, and Tour-Pak speaker grilles are included with the TMS65 pair.

Verify exact motorcycle fitment before purchase, as this kit is made for select Harley-Davidson applications. Installation uses the included RFK-HD14M5 mounting bracket, heat sink, T-harness, power harness, speaker harnesses, bypass plugs, and adapters; a factory-radio flash is required. Follow the applicable Rockford Fosgate tuning guide after installation, including its recommended high-pass configuration and radio settings.
