Velocity RZA500.2 Twin Amplifier Combo – 100W x 2 for Harley-Davidson Touring
The Velocity RZA500.2 Twin Amplifier Combo delivers clean, efficient power for high-output Harley audio systems. Running two compact 100-watt amplifiers gives you the flexibility to power mids, horns, or rear 6×9 speakers with excellent clarity and headroom — all while maintaining a small footprint that fits perfectly inside Harley fairings and saddlebags.
This twin-amp combo is available in two configurations: a premium power kit version that includes AHB’s heavy-duty waterproof wiring harness, and a no-harness version for riders who already have power distribution in place.
