Level 5 full stage for 2024+ Harley Street Glide® — 1,400W amplifier, Carbon Matrix horn coaxials front and rear, Zen-H A2B included
The 24FLXCHX-4X4SG is the Level 5 full stage kit for 2024+ Harley-Davidson Street Glide®. The FLX1400.4 is a 4-channel Class-D amplifier at 350W × 4 at 2Ω — 1,400W total system power. 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 FLX1400.4's current draw. Cicada branded grilles, 24HDAR-SG amplifier mount, and 24HDRO rear harness complete the kit.
If you want the full Level 5 experience with onboard DSP for EQ, crossover, and time alignment, see the 24FLXPCHX-4X4SG (Level 5 PRO — FLX1400.4PRO with built-in DSP). The 2024+ A2B bus requires the Zen-H interface before any aftermarket amplifier — the 24HDZENHCAKIT provides this.
Who This Is For
The 24FLXCHX-4X4SG is for the 2024+ Street Glide® rider who wants the CHX Carbon Matrix horn coaxial speaker system at full stage — front fairing and saddlebag lids — driven by 1,400W of Class-D amplification. The FLX1400.4 delivers 350W RMS per channel at 2Ω, providing the current the CHX65.2 and CHX69.2's 2Ω impedance requires to perform at their ceiling. The 24HDZENHCAKIT decodes the 2024+ A2B digital bus and delivers analog signal to the FLX1400.4's inputs. All hardware — A2B interface, lid kit, power wiring, grilles, and amp mount — is included in the kit.
What This Is Best For
- FLX1400.4 — 350W × 4 at 2Ω, 1,400W total — The FLX1400.4 is a high-power 4-channel Class-D amplifier, rated at 350W RMS per channel at 2Ω. In the 4X4 full stage 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-SG. On the road: at 350W per channel into 2Ω speakers, the FLX1400.4 delivers sustained current output suited to the CHX series' impedance and power handling — the pairing is spec-matched at the amplifier's rated operating point.
- 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 is the distinguishing characteristic of the CHX series — the material's stiffness-to-mass advantage over conventional paper or polypropylene cones is most audible at high power levels, where less rigid cones begin to flex and introduce distortion.
- 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 across the full system. On the road: the matched horn tweeter design between the CHX65.2 and CHX69.2 provides front-to-rear tonal continuity — the system maintains consistent character as the listening balance shifts at speed.
- 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 and delivers signal to the FLX1400.4's inputs. On the road: the 2024+ A2B bus cannot connect directly to an aftermarket amplifier — the 24HDZENHCAKIT is the required interface step, with a plug-and-play harness that connects directly to the FLX1400.4's inputs.
- HDPG4K — 4 AWG power wiring — The FLX1400.4's 1,400W total output requires 4 AWG power and ground conductors to handle current draw without voltage sag under load. The HDPG4K provides 4 AWG cabling sized for the FLX1400.4's current requirements. On the road: at 1,400W rated output, adequate wire gauge is not optional — the HDPG4K is specified to match the FLX1400.4's current draw at full power.
The Bottom Line
The 24FLXCHX-4X4SG is the Level 5 full stage for 2024+ Street Glide® — FLX1400.4 at 350W × 4, 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-SG amplifier mount.

What's Inside the 24FLXCHX-4X4SG
The amplifier is the FLX1400.4 — Cicada Audio's high-power 4-channel Class-D amplifier at 350W RMS per channel at 2Ω. 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-SG. On the road: the FLX1400.4's 1,400W total output at 2Ω is spec-matched to the CHX65.2 and CHX69.2's 2Ω impedance — each channel operates within the amplifier's rated continuous output window.
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, which suppresses resonance modes and reduces distortion at high output levels. The horn-loaded tweeter provides efficiency and directional control suited to the sealed fairing cavity geometry. On the road: the Carbon Matrix cone's rigidity advantage is most apparent at sustained high listening volumes — where a conventional cone begins to flex and colour the output, the CHX65.2 maintains cleaner transient reproduction.
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. On the road: the Carbon Matrix horn coaxial in the lid position provides the same high-output, low-distortion characteristic as the front stage — the system is tonally consistent at any listening balance.
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 and delivers signal directly to the FLX1400.4's inputs. Power wiring is the HDPG4K — 4 AWG power and ground cabling sized for the FLX1400.4's 1,400W current draw. The 24HDRO rear output T-harness connects factory rear saddlebag outputs through the saddlebag area. The 24CHDSGG 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 FLX1400.4'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. If you also want onboard DSP for EQ, crossover configuration, and time alignment, the 24FLXPCHX-4X4SG (Level 5 PRO) includes the FLX1400.4PRO with built-in DSP and the same CHX speaker system.
