Cicada Audio FLX1600.1 — 1,600W Mono Class-D Amplifier for Motorcycle Subwoofers & Midbass

When your Harley needs real bass, the FLX1600.1 brings the thunder.
The Cicada Audio FLX1600.1 is a compact but insanely powerful mono Class-D amplifier engineered specifically for motorcycle subwoofers and high-output midbass systems. Delivering up to 1,600W RMS @ 2Ω and 950W RMS @ 4Ω, this amp is purpose-built to drive 8", 10" and 12" motorcycle subs or serious midbass drivers with clean, controlled authority.

Smaller than many 4-channel amps but capable of true subwoofer power, the FLX1600.1 fits easily into saddlebags, amp racks, and custom enclosures while handling the heat, vibration and voltage swings of real-world Harley-Davidson Touring platforms.

Key Features

  • Massive real-world output: Up to 1,600W RMS @ 2Ω and 950W RMS @ 4Ω.
  • Compact Class-D architecture: High efficiency and low heat — perfect for motorcycle enclosures.
  • Motorcycle-ready durability: Engineered for heat, vibration and 9–16V operation.
  • Advanced crossovers: HPF 10–80 Hz and LPF 80–20 kHz for precise sub and midbass tuning.
  • High damping factor (200): Tight, controlled bass even at extreme listening levels.
  • OEM-friendly turn-on: REM or DC auto turn-on works with Harley Boom!Box and aftermarket head units.
  • System requirement: Requires 4 AWG power wire (HDPG4K) for safe and correct operation.
