Cicada Audio FLX1600.1 — 1,600W Mono Class-D Amplifier for Motorcycle Subwoofers & Midbass
When your Harley needs real bass, the FLX1600.1 brings the thunder.
The Cicada Audio FLX1600.1 is a compact but insanely powerful mono Class-D amplifier engineered specifically for motorcycle subwoofers and high-output midbass systems.
