Cicada Audio HDPro4K – Harley-Davidson 4-Channel CX/DSP Wiring Harness Kit with 8 AWG Power Wire
$465.00 AUD
SKU: HDPro4K
The plug-and-play 4-channel wiring foundation for a Cicada amplifier and DSP on Harley Touring, with 8 AWG power and ground
The Cicada Audio HDPro4K is a complete plug-and-play wiring harness kit for installing a 4-channel amplifier and DSP on a Harley-Davidson® Touring bike. Its pre-terminated Molex connectors mate with Cicada's amplifier range, and the kit includes an 8 AWG power and ground cable set, so you have both the signal path and the current delivery for a modern Class-D and DSP system in one loom. Fits 2014 to 2024 Touring models.
This is Cicada's Harley signal-and-power harness for a 4-channel build. Because the Molex connectors are common across the Cicada amplifier range, the same kit works whether you are running a standard 4-channel amp or adding a DSP processor. For a loom tailored to Cicada's FLX-series amplifiers, the HDFLXPro4K is the FLX-optimised version.
Who This Is For
You are installing a 4-channel amplifier, or an amplifier and a DSP, on a Harley Touring bike and you want the signal routing and the power and ground done once, correctly. The HDPro4K's Molex connectors plug into Cicada 4-channel amplifiers such as the FLX700.4 or FLX1000.4, and the harness carries the signal a processor like the Cicada DSP412PRO needs for a fully tuned system. Add it to cart above, pair it with a DSP412PRO for tuning, and add a HDPG2KD 2 AWG dual-amp power and ground kit for higher-current dual-amp builds.
What This Is Best For
- Connecting a Cicada 4-channel amplifier. Pre-terminated Molex connectors mate with Cicada's amplifier range, so the amp plugs in rather than being wired and soldered by hand.
- Adding a DSP. The harness carries the signal a processor such as the DSP412PRO needs, so the tuning stage drops into the same clean loom.
- Clean, stable power. The included 8 AWG power and ground set feeds a modern Class-D amp and DSP with the current they need, which is what keeps output stable under load.
- A tidy, OEM-style loom. Pre-cut lengths route correctly through the fairing and frame, so the finished install looks factory rather than improvised.
Pair it with the right DSP and amplifier
The HDPro4K carries DSP signal as well as 4-channel amplifier feeds, and its Molex connectors mate across Cicada's amplifier range, so it is not tied to a single amp. For the processor, the current Cicada option is the DSP412PRO, a 4-input by 12-output unit with DiaLD software. If you are running a Cicada FLX-series amplifier and want a loom tailored to it, the HDFLXPro4K is the FLX-optimised alternative. Tell us your amplifier and DSP and we will confirm the kit.
Fitment

|---|---|---|
| Harley-Davidson Touring (Street Glide®, Road Glide®, Ultra, CVO, Tri Glide® Ultra) | Fairing-mounted 4-channel amp and DSP | 2014 to 2024 |
What is in the HDPro4K
The kit does two jobs. The signal harness uses pre-terminated Molex connectors that mate with Cicada's amplifier range, carrying four channels of signal plus a DSP feed on plug-in connectors rather than cut-and-solder joints. In practice: the amplifier and processor plug in and can be serviced later without unpicking a spliced loom.
The 8 AWG power and ground cable set handles current delivery. Correct gauge is what lets a Class-D amplifier and DSP hold voltage under load. On the road: the amp keeps full output on a hot run instead of sagging on an undersized feed.
