Cicada Audio FLX1400.4P — 4-Channel DSP PRO Class-D Amplifier for Harley & Bagger Audio (1400W RMS)

Cicada Audio FLX1400.4P — High-Output 4-Channel DSP PRO Amplifier Built for Serious Motorcycle Audio

This is not “an amp with crossovers”.
The Cicada Audio FLX1400.4P is a true 4-channel DSP power amplifier designed for high-output Harley and bagger builds where space is tight, voltage swings are real, and the music still needs to punch at highway speed. With up to 350W x 4 RMS @ 2Ω, plus a full onboard DSP (crossovers + PEQ), it can replace a separate amp + standalone DSP in many systems.

Key Features

  • Built-in DSP tuning: Full DSP crossovers (HPF/LPF up to 20kHz) + 8-band parametric EQ for proper tuning, staging and protection.
  • Massive real-world output: Up to 350W x 4 RMS @ 2Ω or 700W x 2 bridged @ 4Ω.
  • Motorcycle-voltage stable: Designed to run reliably on 8–16V riding conditions.
  • PRO install ready: 4 AWG power requirement and high-current capability for big builds.
  • Flexible turn-on: REM/DC turn-on options for OEM or aftermarket head units.

Important Notes

  • Requires 4 AWG power wire: Cicada recommends the HDPG4K kit.
  • DSP tuning is PC-based: Cicada’s DSP software page notes FLX1400.4P uses their amp tuning software, and that smartphone DSP apps are not supported at this time.

Fitment

  • Ideal for Harley-Davidson Touring and trike builds (fairing, bags, amp racks, side covers).
  • Perfect for 2Ω front stages using neo mids, horns, and high-output coaxials.
