Cicada Audio FLX1400.4PRO 1400W 4-Channel DSP Motorcycle Amplifier
The Cicada Audio FLX1400.4PRO combines a high-output four-channel Class-D motorcycle amplifier with a full six-channel digital signal processor in one compact chassis. It delivers 350 watts RMS per channel at 2 ohms while giving professional installers the crossover, signal-routing and tuning control needed for serious Harley-Davidson, Indian and custom motorcycle audio systems.
Four DSP channels feed the amplifier's internal outputs while two additional processed pass-through channels remain available for compatible system expansion. Bluetooth audio streaming, USB-C computer tuning and Cicada's DIALD DSP platform make the FLX1400.4PRO a complete power-and-processing solution for high-output bagger audio.
1400 Watts of Power with Six-Channel DSP Control
Four high-output amplified channels, two processed pass-through outputs and professional DSP control in a compact motorcycle-ready amplifier built for loud, clean highway performance.

Four Amplified Channels Plus Two DSP Expansion Channels
The FLX1400.4PRO is more than a four-channel amplifier. Its integrated DSP provides six processed outputs: four channels feed the internal Class-D amplifier while two additional DSP channels provide processed pass-through outputs for compatible future amplifiers.
225W × 4 @ 4Ω
Strong four-channel output for compatible 4-ohm motorcycle speakers, component systems and high-efficiency coaxial configurations.
350W × 4 @ 2Ω
Full 1400-watt output for properly configured 2-ohm motorcycle speaker systems requiring serious highway-speed authority.
700W Ă— 2 Bridged
The amplifier can be bridged into two compatible 4-ohm loads when the system design requires higher two-channel output.
Built-In Six-Channel DSP
Motorcycle audio requires more than amplifier power. Speaker location, wind noise, road noise, open-air listening and unequal distances from the rider all affect the final sound. The FLX1400.4PRO integrates the DSP control required to build the system around the motorcycle rather than relying only on basic amplifier controls.
- Six total DSP channels.
- Four internally amplified DSP outputs.
- Two processed pass-through outputs for compatible expansion.
- High-pass, band-pass and low-pass crossover modes.
- 20 Hz to 20 kHz crossover adjustment range.
- 6, 12, 24 and 48 dB-per-octave selectable slopes.
- Bluetooth audio streaming.
- USB-C computer tuning.
- Cicada DIALD PC and app-based DSP configuration.
Built for Harley-Davidson Bagger Audio
Cicada engineered the FLX1400.4PRO around motorcycle installations, including direct mounting compatibility with compatible Harley-Davidson Road Glide and Street Glide amplifier rack locations.
Its compact aluminum chassis delivers serious output without requiring the physical space normally associated with a 1400-watt four-channel amplifier.
Road Glide
Compact dimensions and multiple mounting options make the FLX1400.4PRO a strong amplifier platform for compatible Road Glide fairing installations.
Street Glide
Designed to work with compatible Street Glide amplifier rack layouts where mounting space is limited.
Custom Baggers
High power density and built-in DSP also make it useful for custom Harley-Davidson, Indian and powersports audio systems.
Motorcycle-Ready Construction
The FLX1400.4PRO uses an extruded aluminum heatsink and a conformal-coated circuit board to improve resistance to the vibration, moisture and dust encountered in motorcycle audio installations.
- Conformal-coated circuit board.
- Extruded aluminum amplifier chassis.
- Cicada ICAD overload protection circuitry.
- Status and clipping LED indicators.
- 4 AWG power connections.
- 12 AWG busbar-style speaker outputs.
- REM, DC and VOX turn-on modes.
- Molex input system supporting RCA or compatible Harley-specific termination.
Bluetooth Audio and USB-C DIALD Tuning
Built-in Bluetooth audio streaming provides a direct playback source for compatible testing, setup and listening. For deeper tuning control, USB-C connectivity allows a computer to connect directly to the amplifier's DSP.
Cicada's DIALD platform provides PC and compatible app-based control over the FLX1400.4PRO DSP, giving installers the tools required to configure crossover behavior and system response around the actual motorcycle and speaker layout.
Designed for Front, Rear and Component Systems
Four high-output amplifier channels make the FLX1400.4PRO suitable for multiple motorcycle audio layouts. It can power front and rear speakers, component networks, saddlebag systems, lowers, fairing speakers or other properly matched combinations.
- Fairing and saddlebag speaker systems.
- Front and rear component configurations.
- 2-ohm high-output motorcycle speakers.
- 4-ohm coaxial and component systems.
- Mid-bass and pro-audio motorcycle speaker systems.
- Systems requiring processed outputs for an additional amplifier.
Electrical System Requirements
Cicada specifies approximately 70 amps of music current draw and up to 150 amps maximum for the FLX1400.4PRO, with a recommended 100-amp fuse for the published music-load specification.
- Use properly sized OFC power and ground wiring.
- FLX1400.4PRO accepts 4 AWG power connections.
- Install appropriate battery-side fuse protection.
- Keep power and ground connections short, clean and secure.
- Confirm motorcycle battery condition before installation.
- Evaluate charging-system capacity for sustained high-output operation.
- Protect all wiring from heat, abrasion, sharp edges and moving components.
