Level 2 front stage for 2024+ Harley Road Glide® — Zen-H A2B included, FLX500.4 amp, CXX65.2 pro coaxials
The 24FLXCXX-4X2RG is the Level 2 front stage kit for 2024+ Harley-Davidson Road Glide® — and unlike the Level 1 kit, it includes everything you need to run. The 24HDZENHCAKIT bundles the NAV-TV Zen-H A2B interface and Cicada direct-connect harness in a single plug-and-play unit, solving the 2024+ A2B signal problem without a separate purchase. Paired with the FLX500.4 4-channel Class-D amplifier at 125W × 4 at 2Ω, CXX65.2 6.5″ 2Ω pro coaxial speakers in the front fairing, and the 24HDRO rear output harness for saddlebag pre-wiring, the 24FLXCXX-4X2RG is a complete front-stage solution out of the box.
The step up from the 24FLXCX-4X2RG (Level 1) is twofold: the CXX65.2 pro coaxial replaces the CX65.2 standard coaxial, and the 24HDZENHCAKIT A2B interface is included rather than sold separately. If you want A2B interface with onboard DSP for independent EQ and time alignment, the Zen-H Pro is available separately — the amplifier, speakers, and harness in this kit are fully compatible with it.
Who This Is For
The 24FLXCXX-4X2RG is for the 2024+ Road Glide® rider who wants a complete, ready-to-install amplified front stage without sourcing the A2B interface separately. The 24HDZENHCAKIT takes the guesswork out of the 2024+ signal path — it connects directly between the factory head unit's A2B output and the FLX500.4's input using a Cicada-specific harness, no additional wiring adapters required. The CXX65.2 is the Level 2 speaker upgrade — a pro coaxial with improved cone and tweeter construction over the Level 1 CX65.2. If you want DSP processing for the A2B conversion alongside this hardware, pair the kit's amplifier and speakers with the Zen-H Pro instead of the included Zen-H.
What This Is Best For
- 24HDZENHCAKIT — A2B interface and Cicada harness, included — The 24HDZENHCAKIT pairs the NAV-TV Zen-H 8-channel A2B to analog converter with a direct-connect harness engineered for Cicada Audio amplifiers. The Zen-H decodes the 2024+ A2B digital audio bus and outputs analog signal to the FLX500.4 — no analog pre-out tapping, no signal level adapters, no separate harness purchase. On the road: the 2024+ A2B architecture means this is a non-negotiable component for any aftermarket amplifier install — having it pre-selected and included removes one of the main friction points in a 2024+ build.
- CXX65.2 — Level 2 pro coaxial front fairing speaker — The CXX65.2 is Cicada Audio's pro coaxial 6.5″ in 2Ω, one tier above the CX65.2 used in the Level 1 kit. It shares the same fairing-optimised mounting format and 2Ω impedance, delivering maximum current draw from the FLX500.4's output channels. On the road: the CXX65.2 handles the sustained high-output conditions of a sealed fairing better than the entry-level CX65.2, with improved cone materials and tweeter construction.
- FLX500.4 — 125W × 4 at 2Ω — The same compact 4-channel Class-D amplifier used in the Level 1 kit, mounted inside the inner fairing via the 24HDAR-RG. Four channels cover the front fairing pair and leave two available for a future rear stage addition. On the road: 125W RMS per channel gives the CXX65.2 genuine output headroom above typical highway ambient noise levels.
- 24HDRO — rear positions pre-wired — The 24HDRO 2024+ rear output T-harness taps the saddlebag speaker outputs during the initial install. A future rear speaker addition connects directly to the existing harness without reopening the wiring. The FLX500.4 already has the output channels available.
- Level 2 — complete system, no separate A2B purchase required — The 24FLXCXX-4X2RG includes the amplifier, speakers, A2B interface, harness, grilles, power wiring, rear pre-wire harness, and amplifier mount. Every item required to go from stock to amplified is in the kit.
Zen-H vs Zen-H Pro — What's Included and What's Available
The 24HDZENHCAKIT included in this kit uses the NAV-TV Zen-H — the non-DSP A2B interface. It decodes the A2B bus and outputs clean analog signal to the FLX500.4. If you want onboard DSP processing — independent EQ, crossover, and time alignment for each channel — the NAV-TV Zen-H Pro can be substituted. The amplifier, CXX65.2 speakers, and remaining hardware in this kit are fully compatible with either interface. Add the Zen-H Pro to your order and set the included 24HDZENHCAKIT aside, or discuss the upgrade with your installer.
The Bottom Line
The 24FLXCXX-4X2RG is the complete Level 2 front stage for 2024+ Road Glide® — FLX500.4 at 125W × 4, CXX65.2 pro coaxials, the 24HDZENHCAKIT Zen-H A2B interface and harness, rear positions pre-wired, and every piece of hardware included. No separate A2B purchase required. Add the kit to cart above.

What's Inside the 24FLXCXX-4X2RG
The A2B interface is the 24HDZENHCAKIT — a bundle of the NAV-TV Zen-H 8-channel A2B decoder and a direct-connect harness engineered for Cicada Audio amplifiers on 2024+ Harley-Davidson Touring models. The Zen-H reads the A2B digital audio bus from the factory head unit and converts it to eight channels of analog output. The Cicada-specific harness routes those analog outputs directly to the FLX500.4's inputs without requiring additional adapters or signal-level matching. On the road: the 2024+ A2B signal path is not optional — every aftermarket amplifier install on these bikes needs an A2B decoder, and the 24HDZENHCAKIT is designed specifically for the Cicada FLX amplifier series.
The front speaker is the CXX65.2 — Cicada Audio's Level 2 6.5″ pro coaxial in 2Ω. The CXX series uses improved cone materials and tweeter construction over the entry-level CX series, with the same fairing-fit format and 2Ω impedance for direct pairing with the FLX500.4. On the road: the CXX65.2 maintains performance under the sustained high-output conditions of a sealed fairing at highway speeds — conditions that thermal and excursion stress entry-level coaxials over time.
The amplifier is the FLX500.4 — a 4-channel Class-D unit at 125W RMS per channel at 2Ω, mounted inside the inner fairing via the 24HDAR-RG. Four channels provide front stage output now and two spare channels for a rear stage later. On the road: compact Class-D form factor means the amplifier fits inside the fairing without structural modification to the fairing itself.
The 24HDRO rear output T-harness routes the saddlebag speaker outputs alongside the rest of the install, ready for future rear speakers. The HDPG8K provides 8 AWG power and ground cabling for the FLX500.4 at the 2014+ Harley-Davidson Touring charging system connection points.
Why the CXX65.2 Over the CX65.2
Both are 6.5″ 2Ω coaxials designed for the Harley-Davidson front fairing. The CX65.2 (Level 1) is Cicada Audio's entry-level fairing coaxial — solid performance at the base of the range. The CXX65.2 (Level 2) uses improved cone and tweeter materials that handle higher sustained output levels and the thermal environment of a sealed fairing more comfortably over time. At 125W RMS per channel from the FLX500.4, the CXX65.2's improved construction is the appropriate match for the amplifier's output capability.
