Amplifiers for 1998-Current Harley-Davidson
An amplifier is where a motorcycle system gets its output. This collection gathers four-channel, two-channel and six-channel amplifiers that suit Harley-Davidson touring builds from 1998 forward, from compact units to high-power designs.
Choose by channel count and power first, then confirm the installation parts for your year and model.

Choosing an Amplifier
Match the amplifier to your system:
- Channel count: two channels for a pair of speakers, four for front and rear pairs, six for a larger system
- Power rating against the speakers you are running
- Built-in DSP, as on the Cicada Audio PRO models and the Diamond Audio NEO models
- Size and mounting: compact units fit tighter spaces
- Your model year, since mounting racks and wiring are year specific
