4-channel T-harness for 2014–2023 Harley-Davidson® Touring — SoundStream WHD14+ running without the 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 WHD14+, feeds them to a Cicada Audio® amplifier, and returns the amplifier's output into the factory speaker harness. The thumb control module that came with your head unit keeps working exactly as it does now. Nothing on the bike is cut or spliced.
This is the version for a WHD14+ running on its own. If your WHD14+ has the WHD.UNLOC kit fitted, or you are running an HDHU.V2, you need the Maestro-integrated version instead — it carries the extra leg that plugs into the Maestro RR2 module. If you have kept the factory Harley radio, the Cicada HDTSLINKAR is the part you want.
Who This Is For
You are running, or about to run, a SoundStream WHD14+ in the fairing of a 2014–2023 Harley-Davidson® Touring bike, without the WHD.UNLOC kit, and you want a Cicada Audio® amplifier mounted in the fairing behind it. That is the standard setup on a bike with fairing speakers and no factory amplifier. It also covers a bike that had factory Boom!™ amplification, where the Cicada is going in to replace that amplifier outright — depending on how your bike is wired that may need a factory amp bypass harness as well, so call us on 07 3350 1354 before ordering if that is your build.
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.
- Your thumb controls keep working — volume, track skip and call answer/end run through the thumb control module supplied with the WHD14+, which this harness leaves untouched. Adding the amplifier does not cost you the handlebar controls you already have.
- 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.
Three Harnesses — Which One Is Yours?
They all suit 2014–2023 Touring, so the model year will not tell you which to order. What decides it is the head unit in your fairing. Factory Harley radio still fitted: Cicada HDTSLINKAR. WHD14+ on its own, no UNLOC kit: this harness. WHD14+ with the WHD.UNLOC kit, or an HDHU.V2: the Maestro-integrated version, which adds the leg for the Maestro RR2 module. If you are not sure, send us your setup before ordering.
The Bottom Line
Four channels out, amplifier output returned to the factory loom, thumb controls untouched, and the whole thing reversible. It removes the stage of the install where noise problems get introduced. Add to cart above — the amplifier still needs its own power and earth run, covered below.

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 WHD14+'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.
There is no Maestro leg on this harness, because a WHD14+ running without the UNLOC kit has no Maestro module to connect to. Handlebar control comes from the thumb control module supplied with the head unit, and that is independent of this loom. On the road: volume, track skip and call answer/end work from the bars exactly as they did before the amplifier went in — what you do not get is on-screen gauges or advanced button mapping, and those need the UNLOC kit rather than a different harness.
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 amplifier power and earth kit is sold separately. No 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.
