Harley-Davidson Motorcycle Audio Tech Centre

Motorcycle audio is a hard engineering problem. Wind noise, engine heat, vibration, weather and a 12-volt electrical system all work against good sound at highway speed. Most Harley stereo advice skips that part.

This Tech Centre explains how motorcycle audio actually works. It is written from the bench and the shop floor, not from a catalogue. It began with the Havoc Roar Stereo, our CNC-machined billet aluminum audio system for un-faired Harley-Davidsons. It has grown into a working library on speakers, amplifiers, head units, power, wiring and installation for every kind of Harley. The guiding principle is function first, then form and style.

Start with the story behind HRS. Then choose your bike: un-faired models such as the Road King, Softail, Dyna and Sportster, or faired touring bikes such as the Street Glide, Road Glide and Electra Glide.
