Cicada Audio FLX1000.4 — 4-Channel High-Power Class-D Motorcycle Amplifier (1000W RMS / Compact Chassis)
Cicada Audio FLX1000.4 — High-Power 4-Channel Class-D Amplifier for Serious Motorcycle Audio
Compact size. Massive output.
The Cicada Audio FLX1000.4 is a palm-sized 4-channel Class-D amplifier designed specifically for high-performance motorcycle audio. Delivering up to 254W × 4 RMS @ 2Ω and 530W × 2 RMS bridged @ 4Ω, this amp easily drives today’s pro-audio mids, horn-loaded drivers and high-efficiency speakers used in modern Harley and touring bike builds.
Engineered for real-world riding — tight mounting spaces, heat, vibration and the voltage swings of motorcycle charging systems — the FLX1000.4 combines flexible crossovers, high efficiency and brutal output for its size, making it the perfect choice for loud, clean bagger systems.
