Level 5 PRO full stage for 2024+ Harley Road Glide® — 1,400W DSP amplifier, Carbon Matrix horn coaxials front and rear, Zen-H A2B included
The 24FLXPCHX-4X4RG is the Level 5 PRO full stage kit for 2024+ Harley-Davidson Road Glide®. The FLX1400.4PRO is a 4-channel Class-D amplifier at 350W × 4 at 2Ω — 1,400W total system power — with an onboard DSP processor. CHX65.2 Carbon Matrix horn coaxials go in the front fairing. CHX69.2 Carbon Matrix 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-RG amplifier mount, and 24HDRO rear harness complete the kit.
If you want the Level 5 CHX speaker system without onboard DSP, see the 24FLXCHX-4X4RG (Level 5 — FLX1400.4, same speakers). 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.
Who This Is For
The 24FLXPCHX-4X4RG is for the 2024+ Road Glide® rider who wants the CHX Carbon Matrix horn coaxial speaker system at full stage — front fairing and saddlebag lids — with DSP-controlled signal processing from the amplifier. The FLX1400.4PRO delivers 350W RMS per channel at 2Ω and includes an onboard DSP processor with independent parametric EQ, crossover, and time alignment per output channel, configurable via PC software. In the 4X4 configuration, channels 1–2 drive the CHX65.2 front pair and channels 3–4 drive the CHX69.2 rear pair — the onboard DSP optimises each pair independently. The 24HDZENHCAKIT decodes the 2024+ A2B digital bus and delivers analog signal to the amplifier's inputs. All hardware is included.
What This Is Best For
- FLX1400.4PRO — 350W × 4 at 2Ω with built-in DSP — 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 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 CHX65.2 front pair; channels 3–4 drive the CHX69.2 rear pair. Mounted inside the inner fairing via the 24HDAR-RG. On the road: the onboard DSP allows the installer to configure the crossover point and EQ for the CHX65.2 and CHX69.2's horn loading characteristics independently — front and rear tuning are separate and not a compromise of a shared crossover network.
- CHX65.2 — Carbon Matrix horn coaxial, front fairing (2Ω) — The CHX65.2 is Cicada Audio's 6.5″ Pro Coaxial Horn speaker in 2Ω, featuring a Carbon Matrix composite cone. The carbon matrix construction delivers a high stiffness-to-mass ratio — reduced cone mass for faster transient response, increased rigidity to suppress breakup modes at high output levels. The horn-loaded tweeter provides high efficiency and controlled dispersion in the front fairing environment. On the road: the Carbon Matrix cone's rigidity advantage is most apparent at sustained high listening volumes — the FLX1400.4PRO's DSP crossover allows the CHX65.2's crossover point to be set precisely for the horn tweeter's loading, maximising efficiency in the fairing cavity.
- CHX69.2 — Carbon Matrix horn coaxial, saddlebag lids (2Ω) — The CHX69.2 is Cicada Audio's 6×9″ Pro Coaxial Horn in 2Ω, sharing the Carbon Matrix cone construction of the CHX65.2. Mounted in the saddlebag lids via the 24CHDLID cut-in kit. The horn coaxial tweeter design maintains tonal consistency with the CHX65.2 front speaker. On the road: the FLX1400.4PRO's onboard DSP allows the rear channels to be tuned independently of the front — EQ and time alignment are applied per channel pair, not as a fixed system-wide setting.
- 24CHDLID — 2024+ Saddlebag Lid Cut-In Kit — The machined lid cut-in kit provides the mounting surround and sealed baffle for the CHX69.2 6×9s in the 2024+ saddlebag lids. On the road: proper baffle mounting via the 24CHDLID improves low-frequency output and cone control from the CHX69.2 compared to a free-air installation.
- 24HDZENHCAKIT — A2B interface and Cicada harness, included — 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. On 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.
- HDPG4K — 4 AWG power wiring — 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 sized for the FLX1400.4PRO's current requirements. On the road: at 1,400W rated output, adequate wire gauge is not optional — the HDPG4K is specified to match the FLX1400.4PRO's current draw at full power.
DSP Is Inside the Amplifier — Zen-H Pro Not Required
The FLX1400.4PRO includes an onboard DSP processor. EQ, crossover configuration, and time alignment are handled inside the amplifier. The 24HDZENHCAKIT in this kit uses the NAV-TV Zen-H (non-DSP) — its role is A2B bus decoding and analog signal delivery to the FLX1400.4PRO's inputs. Signal processing is done by the amplifier's built-in DSP after that point. The Zen-H Pro is not required and its DSP functions are duplicated by the FLX1400.4PRO's internal processor.
The Bottom Line
The 24FLXPCHX-4X4RG is the Level 5 PRO full stage for 2024+ Road Glide® — FLX1400.4PRO at 350W × 4 with onboard DSP, CHX65.2 Carbon Matrix horn coaxials in the front fairing, CHX69.2 Carbon Matrix horn coaxials in the saddlebag lids, 24CHDLID lid cut-in kit, Cicada branded grilles, 4 AWG power wiring, 24HDZENHCAKIT Zen-H A2B interface and harness, and the 24HDAR-RG amplifier mount. No separate processor required. For the same speakers without onboard DSP at a lower price, see the 24FLXCHX-4X4RG. Add the kit to cart above.

What's Inside the 24FLXPCHX-4X4RG
The amplifier is the FLX1400.4PRO — Cicada Audio's high-power 4-channel Class-D DSP amplifier at 350W RMS per channel at 2Ω. The onboard DSP processor is configurable via PC software with independent parametric EQ, crossover, and time alignment per output channel. In the 4X4 configuration channels 1–2 drive the CHX65.2 front pair; channels 3–4 drive the CHX69.2 rear pair. All four channels are in active use. Mounted inside the inner fairing via the 24HDAR-RG. On the road: at 1,400W total output the FLX1400.4PRO's current draw requires 4 AWG power wiring — the HDPG4K in this kit is rated accordingly.
The front speaker is the CHX65.2 — Cicada Audio's 6.5″ Pro Coaxial Horn in 2Ω with Carbon Matrix composite cone. The Carbon Matrix construction provides a high stiffness-to-mass ratio: the cone is stiffer than conventional materials at equivalent mass, suppressing resonance modes and reducing distortion at high output levels. The horn-loaded tweeter provides efficiency and directional control suited to the sealed fairing cavity geometry. The FLX1400.4PRO's onboard DSP allows the crossover point and EQ for the CHX65.2 to be set precisely, independent of the rear channel configuration. On the road: the Carbon Matrix cone's rigidity advantage is most apparent at sustained high listening volumes — the DSP crossover complements this by preventing the horn tweeter from being driven below its optimum crossover point.
The rear speaker is the CHX69.2 — Cicada Audio's 6×9″ Pro Coaxial Horn in 2Ω, sharing the Carbon Matrix cone construction of the CHX65.2. Mounted in the saddlebag lids via the included 24CHDLID lid cut-in kit, which provides a machined baffle surround for sealed mounting of the CHX69.2 driver. The matched horn tweeter design with the CHX65.2 maintains tonal consistency front to rear, reinforced by independent DSP tuning per channel pair. On the road: the rear channels' independent DSP tuning allows time alignment compensation for the saddlebag position relative to the rider's ear — a correction not possible without per-channel DSP.
The A2B interface is the 24HDZENHCAKIT — the NAV-TV Zen-H 8-channel A2B decoder and Cicada direct-connect harness. The Zen-H decodes the 2024+ A2B bus to eight channels of analog output; the FLX1400.4PRO's internal DSP processes those signals before amplification. Power wiring is the HDPG4K — 4 AWG power and ground cabling for the FLX1400.4PRO's 1,400W current draw. The 24HDRO rear output T-harness connects the factory rear saddlebag outputs through the saddlebag area. The 24CHDRGG OEM-style branded grilles cover the front fairing speaker positions.

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 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.
