4-channel T-harness for 2014–2023 Harley-Davidson® Touring — SoundStream HDHU.V2, or WHD14+ with the WHD.UNLOC kit, to any Cicada Audio® amplifier
This harness does the whole amplifier connection in one part. It takes all four speaker-level outputs from a SoundStream HDHU.V2, or a WHD14+ running the WHD.UNLOC kit, feeds them to a Cicada Audio® amplifier, and returns the amplifier's output into the factory speaker harness. The Maestro RR/RR2 connection is carried in the same loom, so gauges and thumb control keep working. Nothing on the bike is cut or spliced.
This is for bikes running an aftermarket SoundStream head unit. If you have kept the factory Harley radio and are only adding amplification, the Cicada HDTSLINKAR Factory Radio T-Harness is the part you want instead.
Who This Is For
You are running, or about to run, a SoundStream HDHU.V2 or WHD14+ in the fairing of a 2014–2023 Harley-Davidson® Touring bike, with a Cicada Audio® amplifier mounted in the fairing behind it. On a WHD14+ build the WHD.UNLOC kit is required — this harness plugs into the Maestro RR2 module that comes with it, and will not suit a WHD14+ running without the kit. If that is your setup, call us on 07 3350 1354 before ordering.
What This Is Best For
- Every Cicada amplifier, one connector — the amplifier end terminates in Cicada's standard input plug, so it mates with any amp in the range, from a compact 4-channel through to the FLX PRO DSP platforms used in our Level 3 PRO Ultra kit. Upgrade the amp later and the harness carries over.
- Signal out and speaker return in one loom — a true T-harness, not a one-way signal lead. Four channels of speaker-level output go to the amplifier, and the amplifier's output comes back through the harness into the factory speaker loom.
- Maestro integration stays intact — the module connection is part of the loom rather than a separate splice, so thumb wheel volume, track skip, gauges and CAN-bus data behave exactly as they did before the amplifier went in.
- Nothing gets cut — head unit loom, OEM speaker harness and amplifier input plug all stay factory. Spliced-in signal tails are the most common reason a used bagger's audio has to be unpicked and rebuilt.
Which Harness Do You Need — This One or the HDTSLINKAR?
It comes down to one question: what radio is in the fairing right now? If you have replaced the factory radio with a SoundStream HDHU.V2, or a WHD14+ running the WHD.UNLOC kit, this harness is the correct part. If the original Harley radio is still in the bike, you need the Cicada HDTSLINKAR, which is built to tap the OEM radio instead. Both suit 2014–2023 Touring — so check the radio, not the bike.
The Bottom Line
Four channels out, amplifier output returned to the factory loom, Maestro integration carried through, and the whole thing reversible. It removes the stage of the install where noise problems and control faults get introduced. Add to cart above — the amplifier still needs its own power and earth run, covered below.
Fitment
| Head Unit | Module Requirement | Years |
|---|---|---|
| SoundStream HDHU.V2 | Maestro RR or RR2, sold separately | 2014–2023 |
| SoundStream WHD14+ | WHD.UNLOC kit required — Maestro RR2 included in that kit | 2014–2023 |
How the Harness Sits in the System
The loom has three ends rather than two. The head unit end takes four channels of speaker-level output from the SoundStream unit's own Class-D output section and carries them to the amplifier's input stage without converting to line level first. The amplifier end returns the Cicada's speaker output back into the factory harness, so the OEM speaker wiring downstream of the radio is used exactly as Harley-Davidson® built it. On the road: fewer conversion stages between source and amplifier means fewer places for noise to enter, and it shows up most at idle, when alternator whine is at its most audible through a fairing.
The Maestro RR/RR2 connection runs inside the same loom, terminated to the module rather than tapped alongside it. On the road: the gauge cluster and the thumb controls keep behaving as one system rather than as an aftermarket stereo bolted next to a motorcycle.
Terminations are machine-crimped, strain-relieved and continuity-tested before dispatch. On the road: hand-soldered joints work-harden under constant fairing vibration and fail intermittently — a channel that drops out over rough bitumen and then tests perfectly back in the workshop.

In the Box
- 1 × MAA Soundstream-to-Cicada 4-channel T-harness, assembled and tested
The Maestro module, the WHD.UNLOC kit and the amplifier power and earth kit are sold separately. No additional Cicada harnesses are supplied with this part.
Completing the Install
The amplifier needs its own power and earth run from the battery — the Cicada HDPG8K 8 AWG kit covers a single fairing-mounted amplifier, and the HDPG4K 4 AWG kit is the step up for higher-current FLX builds.
Because the harness hands the amplifier's output back to the factory loom, fairing speakers are already taken care of. Rear speakers depend on how your bike is wired — some configurations run the rear channels through to the saddlebags or Tour-Pak® on their own, and some need a separate backbone harness to get there. The SaddleTramp BC-9720 Rear Speaker Backbone Harness is the usual answer, with the Deluxe Rear Speaker Split Backbone Harness for builds running Tour-Pak® and saddlebag speakers together. If you are not sure which applies to your bike, call us before ordering.
