8-channel A2B to analog audio interface for 2023.5+ Harley-Davidson Touring. Clean signal before factory processing — the correct foundation for aftermarket amplification.

The NAV-TV ZEN-H is an 8-channel A2B to analog pre-amp interface for 2023.5+ Harley-Davidson Touring models on the Skyline / A2B audio platform — extracts clean, flat, unprocessed audio directly from the A2B digital bus before factory EQ is applied, outputs 8 × RCA at up to 5V RMS, installs in the factory amplifier location with no cutting or splicing, and retains full OEM head unit functionality including volume, balance, fade, sub control, and phone audio.

On modern Harley Touring models with Skyline OS, the factory radio sends audio over the A2B digital bus to the OEM amplifier, where heavy EQ and processing are baked in. Tapping the signal after the factory amp forces installers to first undo that processing before any real tuning can begin — and achieving a flat starting point is never clean or reliable that way. The ZEN-H solves this correctly by inserting before the factory amplifier, extracting audio directly from the A2B bus and delivering eight channels of flat, full-range analog RCA output. That flat signal is what aftermarket amplifiers and DSPs need as a foundation — and the ZEN-H is the only way to get it cleanly on 2023.5+ Harley A2B platforms.

Who This Is For

Riders on 2023.5+ Harley-Davidson Touring models (Skyline / A2B systems) who want to add aftermarket amplifiers properly — not by tapping the speaker outputs or working around the factory amp, but by replacing it with a clean interface and starting from a flat, unprocessed signal. The ZEN-H is the correct front-end for any Cicada amplifier build on these bikes. If you want the A2B interface and DSP combined in one module, the ZEN-H PRO includes an 8-channel DSP built in. If you want to run the ZEN-H with the connection harness to Cicada amps included, see the 24HDZENHCAKIT bundle.

What This Is Best For

• Clean amplifier integration on 2023.5+ Harley A2B bikes — extracts audio before factory processing is applied, providing a flat, full-range starting point that a DSP or DSP-equipped amplifier can work from properly.
• Builds running external DSP or DSP amplifiers — the ZEN-H provides the clean source signal; crossover and tuning happen downstream in the amplifier or DSP stage. If you want DSP built into the interface itself, the ZEN-H PRO is the compact alternative.
• Retaining OEM head unit functions — volume, balance, fade, subwoofer level, EQ presets, phone calls and prompts remain fully operational after install.
• Plug-and-play installation — installs in the factory amplifier location; no cutting, splicing, or coding required.

The Bottom Line

8-channel A2B interface, 8 × RCA output, flat unprocessed signal, plug-and-play, factory functions retained. The correct front-end for aftermarket amplifier builds on 2023.5+ Harley Touring A2B bikes. For interface + harness together, see the 24HDZENHCAKIT. For A2B interface with built-in DSP, see the ZEN-H PRO.

ZEN-H vs ZEN-H PRO — Which One Do You Need?

Choose ZEN-H if you are running a DSP amplifier or an external DSP. Choose ZEN-H PRO if you want an all-in-one interface with DSP built directly into the module.

Technical Specifications

⚠️ Installation & Grounding Requirements

Improper grounding can damage the ZEN-H and void the warranty. Before connecting any RCA cables to the ZEN-H or downstream processors:

• All aftermarket amplifiers must be properly grounded.
• Amplifier ground resistance (referenced to battery ground) must not exceed 1 ohm.
• Do not connect RCA cables until all amplifiers are fully grounded.

Remote Turn-On Note: If using more than one amplifier or DSP, a relay is required (500 mA max remote output).
