Velocity Speaker Design – Amplifiers

Velocity RZA amplifiers for Harley-Davidson® Touring, matched to Velocity's high-output horn-loaded speakers. Choose the RZA500.2 two-channel for a front pair, the RZA1000.4 four-channel for front and rear, or the RZA500.2 twin combo to split a larger system across two amps.

2024 and newer Skyline OS bikes need a compatible A2B interface before an amplifier can connect.
