Cicada Audio FLX700.4 – 4-Channel Amplifier

Cicada FLX700.4 — 4-Channel Micro Amplifier (175W x4)

The FLX700.4 is a compact 4-channel micro amp that delivers up to 175 watts RMS per channel from a chassis just 4.5" long — easy to hide on a bagger, slingshot, side-by-side, or boat. It's a clean, efficient full-range amp for driving a set of speakers, and its tiny footprint makes it one of the simplest power upgrades we install.

Why we recommend it

Run all four channels to your speakers, or bridge to two channels for more output. It runs efficient and quiet (91dB SNR, 200 damping factor) and sets up easily with a 12V–0.2V gain range. Requires 4 AWG power wire (Cicada HDPG4K recommended).
