It combines a pair of direct-fit 6.5-inch upper-fairing speakers, a four-channel A2B amplifier, and a model-specific installation kit. It is designed for riders who want a factory-integrated sound upgrade without adding separate interface hardware.\u003c\/p\u003e\u003cp\u003eThe included TMS24-65 2-way speakers use a long-throw design intended to provide strong output and extended low-frequency response in an open-air motorcycle environment. Each speaker is rated for 150 watts RMS and uses a 1.5-inch voice coil, 4-ohm impedance, and a 50 Hz to 20 kHz frequency response. Their coherent-phase driver layout and integrated crossover support clear, balanced playback from the fairing locations.\u003c\/p\u003e\u003cp\u003ePower comes from the included TMA-1000X4i digital four-channel amplifier, which connects to the motorcycle's Skyline OS through an A2B digital-bus interface. The amplifier supports up to eight-speaker systems, leaving channels and harness provisions available for future system expansion. Rockford Fosgate rates the amplifier at 200 watts RMS per channel at either 4 or 2 ohms.\u003c\/p\u003e\u003cp\u003eRF Connect app control lets the installer load a DSP preset matched to the HD24-STG2 kit through a Bluetooth connection. The app also provides front and rear level adjustment along with selectable high-pass, low-pass, and all-pass crossover settings. This approach allows setup through the amplifier rather than requiring a radio flash.\u003c\/p\u003e\u003cp\u003eThe kit is built for the weather, vibration, and wiring demands of motorcycle use. Element Ready components, grommeted harness protection, and OEM-style Molex and Deutsch DT connections help support a clean installation. It includes Road Glide and Street Glide speaker grilles, amplifier mounting hardware, and the RFK-HD24 wiring kit.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Stage-2 System:\u003c\/strong\u003e Includes two fairing speakers, a four-channel amplifier, and vehicle-specific wiring hardware.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6.5-Inch TMS 2.0 Speakers:\u003c\/strong\u003e Direct-fit 2-way speakers deliver extended response from factory upper-fairing locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1,000-Watt Amplifier Platform:\u003c\/strong\u003e Four-channel A2B amplifier provides power for the included speakers and future expansion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSkyline OS Integration:\u003c\/strong\u003e A2B connectivity works with compatible factory infotainment without radio flashing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRF Connect DSP Setup:\u003c\/strong\u003e Bluetooth app access enables kit-specific tuning presets and crossover adjustments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Ready Construction:\u003c\/strong\u003e Weather-resistant components and protected connectors suit demanding motorcycle conditions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe TMS24-65 speakers use curvilinear poly cones with 10% carbon fill, Santoprene VAST surrounds, Poly-Nomex spiders, and UV-stable Domamid PA66 composite baskets reinforced with 30% glass fiber. Dual neodymium motor structures, vented Kapton voice-coil formers, and corrosion-resistant tin-plated terminals are used to support durability and power handling. The amplifier uses an extruded-aluminum heatsink, convection cooling, and an IPX4-rated chassis.\u003c\/p\u003e\u003cp\u003eInstallation is intended for compatible Harley-Davidson Touring motorcycles with Skyline OS and uses the included RFK-HD24 harness and mounting hardware. The kit includes both Road Glide and Street Glide grille sets, so grille selection should match the motorcycle's fairing style. Rockford Fosgate lists a typical installation time of three hours; use RF Connect to load the HD24-STG2 tune after installation and confirm vehicle compatibility before purchase.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45633546911814,"sku":"HD24-STG2","price":1599.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61qklEaJerL.jpg?v=1784422601","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-hd24-stg2-6-5-harley-audio-kit","provider":"Audio Watt Store","version":"1.0","type":"link"}
