The FLX1400.4PRO is a high-power 4-channel Class-D amplifier at 350W × 4 at 2Ω — 1,400W total system power — with an onboard DSP processor. CH65.4C Larry Frederick Classic horn coaxials go in the front fairing. CH69.4W all-weather horn coaxials go in the saddlebag lids via the 24CHDLID cut-in kit. The 24HDZENHCAKIT A2B interface and Cicada direct-connect harness are included. HDPG4K 4 AWG power wiring handles the FLX1400.4PRO's current draw. Cicada branded grilles, 24HDAR-SG amplifier mount, and 24HDRO rear harness complete the kit.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eIf you only want the front fairing stage, see the \u003ca href=\"\/products\/cicada-audio-24flxpch-4x2sg-front-stage-street-glide-2024-plus\"\u003e24FLXPCH-4X2SG\u003c\/a\u003e (Level 3 PRO front stage). Because the FLX1400.4PRO includes onboard DSP, the Zen-H (non-DSP) in the 24HDZENHCAKIT is the correct A2B interface — the Zen-H Pro is not required.\u003c\/p\u003e\n\n\u003ch3\u003eWho This Is For\u003c\/h3\u003e\n\u003cp\u003eThe 24FLXPCH-4X4SG is for the 2024+ Street Glide® rider who wants high-power, DSP-tuned horn coaxial sound front and rear from a single 4-channel amplifier. The FLX1400.4PRO's 350W RMS per channel at 2Ω gives the CH65.4C and CH69.4W horn coaxials genuine headroom at highway speeds. The onboard DSP processor handles EQ, crossover, and time alignment internally — no separate processor required. The 24HDZENHCAKIT decodes the 2024+ A2B bus and delivers analog signal to the amplifier's inputs. Everything from A2B interface to lid hardware and grilles is in the box.\u003c\/p\u003e\n\n\u003ch3\u003eWhat This Is Best For\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFLX1400.4PRO — 350W × 4 at 2Ω with built-in DSP\u003c\/strong\u003e — The FLX1400.4PRO is Cicada Audio's high-power 4-channel Class-D DSP amplifier. At 350W RMS per channel at 2Ω, it delivers 1,400W total output — the highest single-amplifier output in the Cicada FLX range. The onboard DSP processor provides independent parametric EQ, crossover configuration, and time alignment per output channel, configurable via PC software. In the 4X4 configuration, channels 1–2 drive the CH65.4C front pair; channels 3–4 drive the CH69.4W rear pair.

The horn-loaded tweeter provides high efficiency, controlled dispersion, and extended high-frequency headroom suited to the sealed front fairing environment. At 4Ω, the CH65.4C draws clean, sustained power from the FLX1400.4PRO's output channels. \u003cem\u003eOn the road: the horn tweeter's dispersion characteristics make the CH65.4C particularly effective in the close-proximity listening geometry of a Harley fairing, where horn loading provides better on-axis output at the rider's ear than a dome tweeter at equivalent power.\u003c\/em\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCH69.4W — all-weather horn coaxial, saddlebag lids (4Ω)\u003c\/strong\u003e — The CH69.4W is Cicada Audio's 6×9″ all-weather horn coaxial in 4Ω. All-weather construction is engineered for the saddlebag lid position — exposed to moisture, vibration, and temperature variation. The horn coaxial tweeter design matches the CH65.4C front speaker tonally. Mounted in the saddlebag lids via the 24CHDLID cut-in kit. \u003cem\u003eOn the road: the all-weather rating is appropriate for the lid position, which sees direct exposure that the front fairing position does not. The horn coaxial tweeter maintains tonal consistency with the front stage across the full system.\u003c\/em\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e24CHDLID — 2024+ Saddlebag Lid Cut-In Kit\u003c\/strong\u003e — The machined lid cut-in kit provides the mounting surround and baffle for the CH69.4W 6×9s in the 2024+ saddlebag lids. The CH69.4W speakers included in this kit are the speaker complement to the 24CHDLID. \u003cem\u003eOn the road: the lid cut-in gives the 6×9 a proper sealed baffle rather than a free-air mount, improving low-frequency output and cone control from the CH69.4W.\u003c\/em\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e24HDZENHCAKIT — A2B interface and Cicada harness, included\u003c\/strong\u003e — The 24HDZENHCAKIT pairs the NAV-TV Zen-H 8-channel A2B decoder with a direct-connect harness for Cicada FLX amplifiers. The Zen-H decodes the 2024+ A2B digital audio bus to analog; the FLX1400.4PRO's onboard DSP handles signal processing from that point. The Zen-H Pro is not required with the FLX1400.4PRO. \u003cem\u003eOn the road: the 2024+ A2B signal path requires decoding before it can reach an aftermarket amplifier — the 24HDZENHCAKIT handles this with a harness that connects directly to the FLX1400.4PRO's inputs.\u003c\/em\u003e\n\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHDPG4K — 4 AWG power wiring\u003c\/strong\u003e — The FLX1400.4PRO's 1,400W total output requires 4 AWG power and ground conductors to handle its current draw without voltage sag under load. The HDPG4K provides 4 AWG cabling with Harley-Davidson Touring connection points. \u003cem\u003eOn the road: at 1,400W rated output, adequate wire gauge is critical — the HDPG4K is specified for the FLX1400.4PRO's current requirements at full power.\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"maa-alert\"\u003e\n  \u003ch3\u003eDSP Is Inside the Amplifier — Zen-H Pro Not Required\u003c\/h3\u003e\n  \u003cp\u003eThe FLX1400.4PRO includes an onboard DSP processor.

The NAV-TV Zen-H (included via 24HDZENHCAKIT) decodes the A2B bus and converts it to eight channels of analog output at the correct signal level for the FLX1400.4PRO's inputs. This is not an optional integration step — it is the only way to run an aftermarket amplifier on a 2024+ Harley without signal loss or incompatibility. With the FLX1400.4PRO, A2B decoding (Zen-H) and DSP signal processing (FLX1400.4PRO onboard) are handled by two dedicated devices, each purpose-built for its stage in the signal chain.\u003c\/p\u003e","brand":"Cicada Audio","offers":[{"title":"Default Title","offer_id":50775425384695,"sku":"24FLXPCH-4X4SG","price":6735.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6505\/1639\/files\/Cicada-Audio-24FLXPCH-4X4SG-Level-3-PRO-Full-Stage-Kit-for-2024-Street-Glide-1400W-DSP-Horn-Coaxials.webp?v=1779252353","url":"https:\/\/www.motorcycleaudio.com.au\/products\/cicada-audio-24flxpch-4x4sg-full-stage-street-glide-2024-plus","provider":"Motorcycle Audio Australia","version":"1.0","type":"link"}
