Cicada Audio FLX1400.4PRO – 4-Channel DSP PRO Amplifier, 350W x4

Cicada FLX1400.4PRO — 4-Channel DSP PRO Amplifier (350W x4)

The FLX1400.4PRO is Cicada's flagship compact 4-channel amp — up to 350 watts RMS per channel with a built-in 6-channel DSP (4 amplified, 2 pass-through), Bluetooth audio streaming, and USB-C PC tuning through Cicada's DIALD software. It's engineered to bolt directly into Harley Road Glide and Street Glide amp racks, making it one of the cleanest high-power, fully-tunable upgrades for late-model baggers.

Why we recommend it

This is the do-it-all amp: big power, full DSP tuning, and direct-fit mounting in one conformal-coated, aluminum-encased chassis built for the road. Run four channels or bridge to two (up to 700W each), tune with HP/BP/LP crossovers and selectable 6/12/24/48 dB slopes, and stream over Bluetooth. Multi-mode turn-on (REM/DC/VOX) and premium 4 AWG power connections round it out.
