Velocity Speaker Design — Amplifiers

Velocity Audio Amplifiers for Harley-Davidson Touring

Velocity RZA amplifiers give a Velocity horn-loaded system the power it needs, matched to the brand's high-output front-stage approach. Because Velocity drivers are efficient, they turn amplifier power into real, usable volume, and the RZA range is sized to suit from a two-channel front stage to a four-channel full system. These are the matched way to drive a Velocity build.

This collection carries the RZA500.2 two-channel and the RZA1000.4 four-channel amplifiers, plus the RZA500.2 twin amplifier combo for a dual-amp setup. Match the amplifier to your speaker impedance and channel count, and pair it with the Velocity speakers and kits for a matched result.
