All-in-One Audio Solution


This audio system is housed in a single fairing enclosure and is pre-wired for a simplified plug and play design. Since the speakers, tweeters and amplifier are all pre-installed into the enclosure, there is no need to install anything, so it’s right out of the box performance.

1" Tweeter

On-Axis Design

The 1-inch tweeters are engineered for the ride and how you ride. We measured rider positioning and designed them specifically so that they are always directly pointed at you. Making sure the music is heard over the wind, road, and exhaust noise.

5.25" Midrange

Element Ready™

The 5.25-inch component speakers are purpose built for the harsh motorcycle environment. The speakers and amplifier are designed to stand up to water, dirt, UV, and motorcycle vibration, ensuring that your audio system will stand the test of time.

Stereo Amplifier

Brains with Bluetooth™

All brains with Bluetooth. The amplifier features Bluetooth connectivity for easy device pairing, but what really sets it apart is its intelligence. It uses your GPS to monitor your speed and based on that, it adjusts the volume in real time using its Automatic Volume Control. This happens automatically in the background of the Harley-Davidson Audio Mobile App, so you can pay attention to the road ahead.
