up.\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe Cicada Audio FLX1000.4 is a high-power 4-channel Class-D amplifier built for Harley-Davidson Touring — delivering 254W × 4 RMS at 2Ω and 530W × 2 RMS bridged at 4Ω in a compact chassis designed to fit standard fairing amp trays. Over 45% more output per channel than the FLX700.4 at the same impedance.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThere is a ceiling on what a moderate-power amplifier can do. Run high-sensitivity pro-audio speakers at sustained highway volume, add wind noise, and push the system hard on a long ride — and the gaps in headroom become audible. Distortion creeps in at the top of the gain range, and the system runs out of clean output before it reaches the volume the build was designed for. The FLX1000.4 is the step up for builds where that ceiling has become the limiting factor — real high-output power in a chassis compact enough for standard Harley Touring amp trays, without the size and installation complexity of a full-format car amplifier.\u003c\/p\u003e\n\n\u003ch3\u003eWho This Is For\u003c\/h3\u003e\n\n\u003cp\u003eFor riders who have upgraded their speakers and found their amplifier running out of headroom at speed — or who are building a system around high-output pro-audio drivers from the start and want adequate power in the signal chain from day one.

If the current build needs the FLX1000.4's output with better crossover flexibility for multi-way drivers, the \u003ca href=\"\/products\/cicada-audio-flx700-4-4-channel-motorcycle-amplifier\"\u003eFLX700.4\u003c\/a\u003e covers the 48 dB\/oct slope requirement at 175W × 4.\u003c\/p\u003e\n\n\u003chr class=\"maa-tab-split\"\u003e\n\n\u003ch3\u003ePower Output — What the Numbers Mean\u003c\/h3\u003e\n\n\u003cp\u003eThe FLX1000.4 is rated at two supply voltages, which matters for real-world motorcycle installs where charging voltage varies with RPM and electrical load. At 14.4V — a fully charged, engine-running system — the amp delivers 168W × 4 at 4Ω and 254W × 4 at 2Ω. At 12.5V — closer to battery voltage under heavy load — output drops to 150W × 4 at 4Ω and 220W × 4 at 2Ω. The 2Ω figures drive the product name: 254W × 4 yields approximately 1,000W total RMS at rated voltage.\u003c\/p\u003e\n\n\u003cp\u003eBridged, the amp produces 530W × 2 at 4Ω at 14.4V (461W × 2 at 12.5V) — the configuration for a high-output two-channel front stage, a mid-bass enclosure, or a compact subwoofer application where maximum per-channel power is the priority.\u003c\/p\u003e\n\n\u003ch3\u003eCrossover and Signal Control\u003c\/h3\u003e\n\n\u003cp\u003eThe FLX1000.4 runs HPF, LPF, or Full Range crossover modes with a frequency range of 30 Hz – 300 Hz and a fixed 12 dB per octave slope. This covers the primary use cases for a high-power 4-channel motorcycle amp — high-pass filtering for fairing speakers, low-pass filtering for a rear mid-bass or subwoofer channel, and full-range operation for coaxial speakers.\u003c\/p\u003e\n\n\u003cp\u003eThe 12 dB\/octave slope is well-matched to coaxial and mid-bass builds. For builds that require steeper driver-separation slopes — separating dedicated horn tweeters and midrange drivers where 24 or 48 dB\/octave gives cleaner isolation — the \u003ca href=\"\/products\/cicada-audio-flx700-4-4-channel-motorcycle-amplifier\"\u003eFLX700.4\u003c\/a\u003e's crossover architecture handles that role more precisely. The FLX1000.4 is the high-output choice for coaxial and mid-bass builds where headroom and current delivery matter more than multi-octave crossover flexibility.\u003c\/p\u003e\n\n\u003cp\u003eInput sensitivity runs 0.2V – 12V, covering both OEM Harley signal levels and standard RCA output from aftermarket head units.\u003c\/p\u003e\n\n\u003ch3\u003eSystem Integration\u003c\/h3\u003e\n\n\u003cp\u003eThe FLX1000.4 accepts high-level speaker output from the factory Harley Boom! Box radio directly — no additional converter required for 2014–2023 models — or low-level RCA from any aftermarket head unit.\u003c\/p\u003e\n\n\u003cp\u003eTurn-on supports REM and DC offset modes. DC offset turn-on is useful on older Harley platforms where routing a clean remote wire to the factory head unit is not practical.\u003c\/p\u003e\n\n\u003cp\u003eAt 60A music-level current draw, the FLX1000.4 operates at the upper limit of most factory Harley charging systems. Maximum draw is 116A; a 120A fuse is recommended on the power feed. For builds pairing the FLX1000.4 with additional amplifiers or high-draw accessories, verify total system current load against the bike's alternator output before finalising the design.\u003c\/p\u003e\n\n\u003cp\u003eThe FLX1000.4 does not include onboard DSP. For builds requiring time alignment, multi-band EQ, or advanced signal routing, pair with a dedicated DSP processor upstream of the amp inputs.\u003c\/p\u003e\n\n\u003ch3\u003e2024+ Platform Notes\u003c\/h3\u003e\n\n\u003cp\u003eFor 2023.5 CVO and 2024+ Harley-Davidson Touring models running Skyline OS, the FLX1000.4 can be integrated as part of an aftermarket audio system when paired with a NAV-TV ZEN-H or ZEN-H Pro. The ZEN-H \/ ZEN-H Pro handles the Skyline OS signal interface — the FLX1000.4 then receives the processed output and powers the speakers downstream from it. Without a NAV-TV ZEN-H or ZEN-H Pro, integration with a 2023.5 CVO or 2024+ Harley is not supported. For 2014–2023 models (excluding 2023.5 CVO), the high-level input connects directly to the factory Boom!

At 14.4V — a fully charged, engine-running system — the amp delivers 225W × 4 at 4Ω and 350W × 4 at 2Ω. At 12.5V — closer to battery voltage under heavy load — output drops to 200W × 4 at 4Ω and 300W × 4 at 2Ω. The 2Ω figures at 14.4V drive the product name: 350W × 4 yields approximately 1,400W total RMS at rated voltage.\u003c\/p\u003e\n\u003cp\u003eBridged, the amp produces 700W × 2 at 4Ω at 14.4V (600W × 2 at 12.5V) — the configuration for maximum per-channel output to a dedicated mid-bass enclosure, subwoofer, or high-output two-channel front stage. At 4Ω bridged, the amplifier sees a 2Ω load per side — within the FLX1400.4's rated bridged impedance specification. \u003cem\u003eOn the road: at 50A music-level current draw, the FLX1400.4 operates within a cautious margin for most factory Harley charging systems under normal riding conditions — notably more conservative than the FLX2000.4's 60A draw or the lithium-dependent current profile of the FLX2000.4 at full rated output.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCrossover and Signal Control\u003c\/h3\u003e\n\u003cp\u003eThe FLX1400.4 runs HPF, LPF, or Full Range crossover modes with a frequency range of 30 Hz–300 Hz and a fixed 12 dB per octave slope. This covers the primary use cases for a high-power 4-channel motorcycle amp — high-pass filtering for fairing speakers, low-pass filtering for a rear mid-bass or subwoofer channel, and full-range operation for coaxial speakers. The 12 dB\/octave slope is well-matched to coaxial and mid-bass builds.\u003c\/p\u003e\n\u003cp\u003eFor builds requiring steeper driver-separation slopes — dedicated horn tweeters and midrange drivers where 24 or 48 dB\/octave gives cleaner isolation — the \u003ca href=\"\/products\/cicada-audio-flx700-4-4-channel-motorcycle-amplifier\"\u003eFLX700.4\u003c\/a\u003e's crossover architecture handles that role at 175W × 4. The FLX1400.4 is the choice when maximum per-channel output for coaxial and mid-bass builds is the priority. Input sensitivity runs 0.2V–12V, covering both OEM Harley signal levels and standard RCA output from aftermarket head units.\u003c\/p\u003e\n\n\u003ch3\u003eSystem Integration\u003c\/h3\u003e\n\u003cp\u003eThe FLX1400.4 accepts high-level speaker output from the factory Harley Boom! Box radio directly — no additional converter required for 2014–2023 models — or low-level RCA from any aftermarket head unit. Turn-on supports REM and DC offset modes. DC offset turn-on is useful on older Harley platforms where routing a clean remote wire to the factory head unit is not practical.\u003c\/p\u003e\n\u003cp\u003eAt 50A music-level current draw, the FLX1400.4 operates within a cautious margin for most factory Harley charging systems under normal riding conditions — but maximum draw is 220A, and the wiring infrastructure must be rated accordingly. A 120A fuse is required on the power feed. For builds pairing the FLX1400.4 with additional amplifiers or high-draw accessories, verify total system current load against the bike's alternator output and battery capacity before finalising the design.

The ZEN-H \/ ZEN-H Pro handles the Skyline OS signal interface — the FLX1400.4 then receives the processed output and powers the speakers downstream from it. Without a NAV-TV ZEN-H or ZEN-H Pro, integration with a 2023.5 CVO or 2024+ Harley is not supported.

Class-D switches the output stage at high frequency rather than running it continuously in the linear region, which is why 80% efficiency is achievable at this output level from a chassis that fits a standard fairing amp tray. \u003cem\u003eOn the road: the FLX1400.4PRO generates substantially less heat at sustained highway volume than a comparable AB-class design — relevant when the amp is mounted in a sealed fairing cavity with limited airflow.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003econformal-coated circuit board\u003c\/strong\u003e seals the PCB surface against moisture ingress, condensation, and fine particulate. Combined with the fully extruded aluminium heatsink enclosure, the board is protected from the environment a motorcycle fairing creates — temperature cycling, humidity variation, and vibration that would degrade an uncoated board over time. \u003cem\u003eOn the road: reliable operation across Australian riding conditions, from coastal humidity to outback heat cycles, without the gradual performance degradation that moisture and vibration cause on unprotected boards.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eICAD overload protection circuit\u003c\/strong\u003e monitors the output stage continuously and intervenes before a fault condition develops into component damage. Unlike a standard thermal cutout that reacts after the fact, ICAD limits operation within safe parameters during sustained high-output operation. \u003cem\u003eOn the road: the amp recovers from a momentary overload condition and keeps playing rather than shutting down and requiring a key cycle to reset.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy the 6-Channel DSP Architecture\u003c\/h3\u003e\n\u003cp\u003eThe DSP in the FLX1400.4PRO is a 6-channel processor: 4 channels feed the amplifier output stage directly, and 2 channels are available as processed pass-through outputs for a downstream amplifier. This is a different architecture from a 4-channel DSP amp — the pass-through outputs allow the FLX1400.4PRO to function as the central signal processor for a multi-amp system, not just as an amplifier with tuning capability.\u003c\/p\u003e\n\u003cp\u003eIn a two-amp build, the FLX1400.4PRO handles the front stage at 350W × 4 while sending a processed, time-aligned signal from the pass-through outputs to a rear-stage or subwoofer amplifier downstream. The entire system runs through one DSP, one tuning interface, one fairing amp tray position. The alternative — a standalone DSP upstream feeding two separate amplifiers — adds wiring runs, a second mounting position, and a more complex signal chain to achieve the same result.\u003c\/p\u003e\n\u003cp\u003eThe DSP crossover covers the full 20 Hz–20 kHz range with HP, BP, and LP modes at selectable slopes of 6, 12, 24, and 48 dB per octave. Bandpass mode is available for mid-bass channel control without relying on upstream or downstream filtering. The 48 dB\/oct slope provides the sharp driver separation needed for active tweeter and midrange configurations — the steepest slope available in any amplifier in the FLX range.\u003c\/p\u003e\n\u003ch3\u003eWhy Onboard DSP and Bluetooth Streaming\u003c\/h3\u003e\n\u003cp\u003eEvery DSP amplifier in the FLX range is tuned over USB-C with DIALD™ Windows PC software. The FLX1400.4PRO adds Bluetooth® audio streaming — a receiver feature that is separate from tuning.\u003c\/p\u003e\n\u003cp\u003eDSP tuning is done over USB-C with the DIALD™ Windows PC software — adjusting per-channel EQ, crossover frequency, and time alignment while hearing the actual result through the speakers on the bike, not through studio monitors. The \u003ca href=\"\/products\/cicada-audio-c2c-usbc-waterproof-extension-kit-dsp\"\u003eC2C USB-C waterproof extension kit\u003c\/a\u003e mounts the USB-C access point at the cockpit so tuning sessions don't require removing a fairing panel to reach the amplifier. Settings are stored on the unit, so the laptop is only needed when you change the tune.\u003c\/p\u003e\n\u003cp\u003eBluetooth® audio streaming means the DSP can also function as a Bluetooth® receiver — useful for bikes without a Bluetooth-capable head unit or as a direct streaming path independent of the head unit's source.\u003c\/p\u003e\n\u003ch3\u003ePower Output — What the Numbers Mean\u003c\/h3\u003e\n\u003cp\u003eThe FLX1400.4PRO is rated at 14.4V — a fully charged, engine-running system. At that voltage, the amp delivers 225W × 4 at 4Ω and 350W × 4 at 2Ω. The 2Ω figures at 14.4V drive the product name: 350W × 4 yields approximately 1,400W total RMS at rated voltage. Bridged, the amp produces 700W × 2 at 4Ω — the configuration for maximum per-channel output to a dedicated mid-bass enclosure, subwoofer, or high-output two-channel front stage.\u003c\/p\u003e\n\u003cp\u003eIn bridged operation, the DSP's onboard crossover handles channel filtering before the signal reaches the output stage — the sub or mid-bass channel receives a DSP-processed low-pass signal rather than relying on amp-level crossover control downstream. The 2CH\/4CH input switch on the chassis selects bridged or four-channel operation directly without needing to access the DSP software.\u003c\/p\u003e\n\u003ch3\u003eSystem Integration\u003c\/h3\u003e\n\u003cp\u003eThe FLX1400.4PRO accepts high-level speaker output from the factory Harley Boom!™ Box radio directly via Molex® inputs — the same connector format as H-D® factory termination, no adaptor required for 2014–2023 models — or standard RCA from any aftermarket head unit. The Molex® input accepts RCA or H-D® custom termination in the same connector housing, which simplifies integration across both factory and aftermarket head unit installs.\u003c\/p\u003e\n\u003cp\u003eTurn-on supports REM, DC offset, and VOX modes. DC offset turn-on is useful on older Harley platforms where routing a clean remote wire to the factory head unit is not practical. VOX (voice-activated) turn-on triggers the amplifier from signal presence — useful for installs where neither a clean remote wire nor reliable DC offset is available.\u003c\/p\u003e\n\u003cp\u003eAt 70A music-level current draw, the FLX1400.4PRO's wiring requirement is well-defined: a 100A fuse on the power feed and 4 AWG for the power and ground run.

For 2014–2023 models (excluding 2023.5 CVO), the high-level Molex® input connects directly to the factory Boom!™ Box radio.\u003c\/p\u003e\n\u003ch3\u003eTechnical

At 12.5V — the lower end of a system under heavy load — output drops to 275W × 4 at 4Ω and 450W × 4 at 2Ω.

At 4Ω bridged, the amplifier sees a 2Ω load per side — within the FLX2000.4's rated bridged impedance specification. A lithium battery is particularly important in bridged configurations where sustained current demand is highest. \u003cem\u003eOn the road: bridged at 1,044W into a Tour-Pak subwoofer, voltage sag from a lead-acid battery will compress dynamic peaks and reduce effective output — a lithium battery maintains stable supply voltage under the kind of sustained current draw the FLX2000.4 generates.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eCrossover and Signal Control\u003c\/h3\u003e\n\u003cp\u003eThe FLX2000.4 runs HPF, LPF, or Full Range crossover modes with a frequency range of 30 Hz–300 Hz and a fixed 12 dB per octave slope. This covers the primary use cases for a high-power 4-channel motorcycle amp — high-pass filtering for fairing speakers, low-pass filtering for a rear mid-bass or subwoofer channel, and full-range operation for coaxial speakers. The 12 dB\/octave slope is well-matched to coaxial and mid-bass builds.\u003c\/p\u003e\n\u003cp\u003eFor builds requiring steeper driver-separation slopes between dedicated tweeter and midrange drivers, the \u003ca href=\"\/products\/cicada-audio-flx700-4-4-channel-motorcycle-amplifier\"\u003eFLX700.4\u003c\/a\u003e's crossover architecture handles that role at 175W × 4 with slopes up to 48 dB\/octave. The FLX2000.4 is the choice when maximum output for high-sensitivity coaxial and mid-bass builds is the sole priority.

At 14.4V — a fully charged, engine-running system — the amp delivers 950W at 4Ω and 1,600W at 2Ω. At 12.5V — closer to battery voltage under heavy load — output drops to 670W at 4Ω and 1,250W at 2Ω. For builds running a 2Ω subwoofer or mid-bass driver, the 2Ω figure at 14.4V is the rated operating condition and the number that drives the product name.\u003c\/p\u003e\n\u003cp\u003eThe choice between 2Ω and 4Ω driver impedance affects both power output and amplifier thermal margin. At 2Ω, the amp delivers rated maximum output; at 4Ω, the amp runs cooler with more thermal headroom. For subwoofer applications where maximum excursion and output are the priority, 2Ω is the correct choice. For mid-bass builds where sustained thermal stability across a full riding day matters as much as peak output, 4Ω is worth considering. \u003cem\u003eOn the road: the FLX1600.1 running a 2Ω sub at 1,600W sustained highway volume will generate more heat than a 4Ω build — relevant if the amp is mounted in a sealed Tour-Pak or saddlebag position with limited airflow.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eCrossover and Signal Control\u003c\/h3\u003e\n\u003cp\u003eThe FLX1600.1 runs HPF and LPF crossover modes with a fixed 12 dB per octave slope. The HPF range covers 10–80 Hz — used as a subsonic filter to protect the driver from excursion below its usable frequency range. The LPF range covers 80 Hz–20 kHz — the main crossover point that rolls the mono channel off above the sub or mid-bass driver's operating range.\u003c\/p\u003e\n\u003cp\u003eThe LPF extending to 20 kHz means the FLX1600.1 can also operate as a full-range mono amplifier when the LPF is set above the speaker's usable range — relevant for custom single-driver builds where a dedicated mono amp is required without a low-pass restriction. Input sensitivity runs 0.2V–12V, covering both OEM Harley signal levels and standard RCA output from aftermarket head units or DSP pass-through outputs. \u003cem\u003eOn the road: DSP pass-through from the FLX700.4PRO or FLX1400.4PRO delivers a pre-filtered, time-aligned low-pass signal directly to the FLX1600.1 inputs — the sub channel arrives already crossover-processed, and the FLX1600.1 adds the power stage without a second crossover stage in the signal path.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eSystem Integration\u003c\/h3\u003e\n\u003cp\u003eThe FLX1600.1 accepts high-level speaker output from the factory Harley Boom!
