Cicada Audio FLX2000.4 – 4-Channel Amplifier, 500W x4

Cicada FLX2000.4 — 4-Channel Amplifier (500W x4)

The FLX2000.4 is a high-output compact 4-channel amp, delivering up to 542 watts RMS per channel from a chassis just 8.6" long. It's built for demanding full-range systems that want serious clean power, and still fits the install spaces of a bagger, slingshot, side-by-side, or boat.

Why we recommend it

Run all four channels hard, or bridge to two channels (up to 1,044W each) for big output. Efficient and quiet (91dB SNR, 200 damping factor) with an easy 12V–0.2V gain range. At this power level it wants a healthy electrical system — lithium battery upgrade and 4 AWG power wire recommended.
