Hertz Audio
Hertz Audio is an Italian electronics brand with a serious reputation in car and motorcycle audio — known for tight engineering tolerances, consistent output, and products that measure as well as they sound. The Hertz HMX series is designed specifically for motorcycle use: compact amplifiers, DSP units, and speakers sized and rated for the heat, vibration and power demands of a Touring bike install.
The Hertz range for Harley-Davidson covers three common upgrade paths: the HMX amplifier series for riders who want to drive their speakers harder, the H8 DSP Amplifier for builds that need both power and full tuning control in a single unit, and the HMX speaker range for riders who want a fully integrated Hertz system. All Hertz components are selected by MAA for confirmed compatibility with the Harley Touring platform.
Hertz products occupy the middle-to-upper tier of what MAA stocks — well above the generic motorcycle audio bracket, and matched in price and performance with Cicada and Precision Power for different build priorities.
