Level 4 PRO front stage for 2024+ Harley Road Glide® — active 2-way component system, FLX700.4PRO DSP, Carbon Matrix mid-bass
The 24FLXPCM-4X4RG is the Level 4 PRO front stage kit for 2024+ Harley-Davidson Road Glide®. It is an active 2-way component system: the CM65.4X Carbon Matrix 6.5″ mid-bass and the RR075T tweeter (included in the 24CHDRGGTK-075 grille kit) each run on dedicated amplifier output channels, with the FLX700.4PRO's onboard DSP processor setting the active crossover point between them. There is no passive crossover network in this system — the DSP routes signal directly to each driver type. The 24HDZENHCAKIT A2B interface and Cicada direct-connect harness are included. The 24HDAR-RG amplifier mount and HDPG6K 6 AWG power wiring complete the kit.
At Level 4, the step up from the Level 3 PRO CH65 horn coaxial is the shift from a coaxial design to an active component system. In the 24FLXPCM-4X4RG, the mid-bass and tweeter are separate drivers, each powered by dedicated amplifier channels, with no passive crossover filtering losses between the amplifier and the driver. The FLX700.4PRO's DSP sets the crossover frequency, slope, and individual EQ for each channel independently.
Who This Is For
The 24FLXPCM-4X4RG is for the 2024+ Road Glide® rider who wants the precision of an active 2-way component system in the front fairing, driven by a DSP amplifier with independent channel control. The CM65.4X Carbon Matrix mid-bass handles the lower frequency range; the RR075T tweeter in the 24CHDRGGTK-075 grille kit handles above the DSP crossover point. No passive crossover required — signal routing is done entirely within the FLX700.4PRO's DSP processor before amplification.
What This Is Best For
- Active 2-way component system — mid-bass and tweeter on separate amp channels — The CM65.4X and RR075T each receive their own amplified signal, band-limited by the FLX700.4PRO's DSP crossover. This eliminates passive crossover insertion loss, gives the installer direct control over each driver's frequency range and level, and allows the CM65.4X to focus entirely on mid-bass reproduction without a passive network limiting its output. On the road: an active system allows the FLX700.4PRO's DSP to be tuned to the specific acoustic characteristics of the Road Glide® fairing — adjusting the crossover frequency, slopes, and relative levels for the listening position.
- CM65.4X — Carbon Matrix 6.5″ mid-bass (4Ω) — Cicada Audio's Carbon Matrix cone mid-bass driver for the front fairing. The Carbon Matrix cone construction provides high stiffness-to-weight ratio for low coloration in the mid-bass range. In the active component system, the CM65.4X operates without a passive crossover between it and the amplifier — it receives full, band-limited signal directly from the FLX700.4PRO's output stage. On the road: without the resistive and reactive losses of a passive crossover network, the CM65.4X receives the full output of its dedicated amplifier channel, improving efficiency and reducing heat in the crossover.
- 24CHDRGGTK-075 — Road Glide® Grille + RR075T Tweeter Kit (4Ω) — The 24CHDRGGTK-075 provides the Cicada branded OEM-style grille for the 2024+ Road Glide® front fairing, with an integrated RR075T tweeter in 4Ω. The tweeter runs on its own dedicated FLX700.4PRO output channel above the DSP crossover point. On the road: the tweeter's position in the grille mount places it at the optimal acoustic location in the fairing for high-frequency dispersion toward the listening position.
- FLX700.4PRO — 175W × 4 at 2Ω with built-in DSP — Four channels, each independently configurable via the FLX700.4PRO's PC-configurable DSP. In the 4X4 configuration: channels 1–2 drive the CM65.4X mid-bass pair; channels 3–4 drive the RR075T tweeter pair. The DSP crossover determines the frequency split, with parametric EQ available per channel. Mounted inside the inner fairing via the 24HDAR-RG. On the road: having DSP integrated into the amplifier means the active crossover, EQ, and level control are all adjustable from a single device, without an additional processor in the signal chain.
- 24HDZENHCAKIT — A2B interface and Cicada harness, included — The NAV-TV Zen-H decodes the 2024+ A2B digital audio bus and outputs analog signal to the FLX700.4PRO's inputs. The Cicada direct-connect harness routes those outputs directly to the amplifier's input connectors. The Zen-H Pro is not required — the FLX700.4PRO's onboard DSP handles all signal processing. On the road: the 2024+ A2B architecture requires a decoder before any aftermarket amplifier — the 24HDZENHCAKIT is the correct interface for the Cicada FLX amplifier series.
DSP Is Inside the Amplifier — Zen-H Pro Not Required
This kit's amplifier includes an onboard DSP processor. EQ, crossover configuration, and time alignment are handled inside the amplifier — the DSP actively routes signal to the mid-bass and tweeter channels independently. The 24HDZENHCAKIT uses the NAV-TV Zen-H (non-DSP), which decodes the A2B bus and delivers analog signal to the amplifier's inputs. Signal processing is done by the amplifier's built-in DSP from that point. The Zen-H Pro is not required — its DSP functions are handled by the amplifier's internal processor.
The Bottom Line
The 24FLXPCM-4X4RG is the Level 4 PRO front stage for 2024+ Road Glide® — FLX700.4PRO at 175W × 4 with onboard DSP, CM65.4X Carbon Matrix mid-bass, RR075T tweeter via 24CHDRGGTK-075 grille kit, active 2-way crossover from the DSP, 24HDZENHCAKIT A2B interface, 6 AWG power wiring, and the 24HDAR-RG amplifier mount. No passive crossover. No separate processor. Add the kit to cart above.

What's Inside the 24FLXPCM-4X4RG
The amplifier is the FLX700.4PRO — Cicada Audio's ultra-compact 4-channel Class-D DSP amplifier at 175W RMS per channel at 2Ω. The onboard DSP processor provides independent parametric EQ, crossover configuration, and time alignment per output channel. In the 4X4 active component configuration, channels 1–2 are configured for the CM65.4X mid-bass pair and channels 3–4 for the RR075T tweeter pair, with the DSP setting the crossover frequency and slopes between them. Mounted inside the inner fairing via the 24HDAR-RG. On the road: the active crossover in the FLX700.4PRO eliminates the passive crossover network entirely — each driver receives a dedicated, band-limited, amplified signal with no passive component losses.
The mid-bass driver is the CM65.4X — Cicada Audio's 6.5″ Carbon Matrix cone mid-bass in 4Ω. Designed for the sealed front fairing environment, the CM65.4X operates as a dedicated mid-bass driver — it is not a full-range speaker, and does not need to be. In the active system, it handles only the frequency range below the FLX700.4PRO's DSP crossover point, allowing full use of its cone excursion and voice coil design within that range. On the road: a dedicated mid-bass driver without passive crossover loading handles sustained high-output mid-bass reproduction more cleanly than a full-range coaxial at equivalent power levels.
The tweeter is the RR075T, supplied as part of the 24CHDRGGTK-075 — the Cicada branded OEM-style grille for the 2024+ Road Glide® fairing, with the tweeter integrated into the grille mount. The RR075T operates on its own FLX700.4PRO output channels above the DSP crossover point. The HDPG6K provides 6 AWG power and ground cabling for the FLX700.4PRO's current draw.

Why a Zen-H Is Required on 2024+ Harley Models
The 2024+ Harley-Davidson Touring platform replaced the traditional analog pre-out signal path with A2B — a digital audio bus protocol used for the factory head unit's audio outputs. Aftermarket amplifiers expect analog signal; they cannot connect directly to an A2B output. 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 amplifier'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. The amplifier's onboard DSP then handles all signal processing, including the active crossover between mid-bass and tweeter channels.
