Rockford Fosgate HD24-STG3


Performance Engineered

Each component of the Stage-3 kit is meticulously engineered for peak performance. The 6.5” and 6x9 speakers feature a heat-resistant motor structure and radiator ring that efficiently dissipate heat, ensuring consistent, powerful sound even under the most demanding conditions. Complementing the speakers, the 1000-watt digital amplifier delivers robust performance and is future-ready for expanding your system with additional speakers.


Plug and Play Design

Stage-3 delivers a complete plug-and-play solution in a single box, featuring direct-fit, model-specific 6.5” and 6x9” speakers, amplifier mounting plates, a saddlebag installation kit, and grilles. Engineered for seamless integration with the Skyline OS Harley-Davidson infotainment system — it requires no radio flashing — making installation straightforward and hassle-free.


Precision-Tuned

Featuring long-throw woofers for high output and deep, extended low-end response, these speakers deliver powerful yet balanced sound. The large voice coil and extended frequency range enhance bass output, ensuring louder, more dynamic, and long-lasting performance.


Total Control

With the RF Connect app, tuning your system is as easy as tapping your screen. Connect to the amplifier via Bluetooth to instantly load a DSP tune matched to your exact Rockford Fosgate motorcycle audio kit. You can also fine-tune your ride by adjusting gain and crossover settings digitally, customizing your sound, your way, all from your smartphone.


Element Ready

Purpose-built for the harsh motorcycle environment, this kit includes watertight, grommeted installation harnesses with OEM-style and Deutsch™ DT connectors. Designed to withstand water, dirt, UV exposure, and constant vibration, it ensures long-lasting, reliable audio performance.
