Rockford Fosgate HD14-STG3 2014+ Harley-Davidson Road Glide & Street Glide Stage-3 Kit (Gen-3)

Motorcycle enthusiasts know that the thrill of the ride comes with a soundtrack from Rockford Fosgate’s HD14-STG3 Stage-2 kit. However, getting crystal-clear, high-performance audio on a motorcycle can be a challenge. The M5 Audio Kits from Rockford Fosgate are the latest innovation in motorcycle audio technology. These kits are designed to provide riders with the loudest and clearest audio systems available, making for an unparalleled on-bike audio experience.

Plug-and-Play Design

Installing an audio system on a motorcycle can be a daunting task. The M5 Audio Kits feature a plug-and-play design that ensures a quick and easy installation process. Everything needed for installation is included in the HD14-STG3 kit, which means less time in the garage and more time out on the open road.

Full Throttle Output

The M5 Audio Kits are designed to perform at freeway speeds, overcoming wind, road, and exhaust noise. The speakers and amplifiers are specifically tuned and designed to provide riders with the ultimate audio experience on their bike. With the M5 Audio Kits, riders can expect unparalleled sound quality and volume.

RF3 (Rockford Factory Fit and Finish)

One of the key benefits of the HD14-STG3 Audio Kit is their RF3 design. These components are purpose-built to match and complement the factory fit and finish of the bike. This ensures the best-in-class fitment and look, providing a sleek and seamless appearance that is both functional and stylish.

Element Ready™

Motorcycles are often exposed to harsh environmental conditions such as water, dirt, UV, and vibration. The M5 Audio Kits are designed to stand up to these conditions, featuring speakers and amplifiers that are Element Ready™. These components are specifically designed to withstand these conditions, ensuring that the audio system will stand the test of time.
