Amplifiers for the Harley-Davidson Tri Glide® Ultra (2014–2025)
Trike amplifiers in this collection connect by the same platform rules as the equivalent two-wheel Touring bikes, which means the year and audio system decide the wiring. Pre-2014 trikes output an analogue speaker-level signal that an amplifier reads through a high-level input. The Tri Glide Ultra from 2014 to 2025 connects using the factory Boom! Box speaker-level outputs, either directly into an amplifier with high-level inputs or through a suitable integration harness where required. Skyline OS and A2B digital audio arrive on the trike range in 2026, on the Road Glide 3 and Street Glide 3 Limited — those need a compatible A2B interface, such as the NAV-TV ZEN-H, before an amplifier can connect. A 2024 or 2025 Tri Glide Ultra is not one of them; it is still Boom! Box.
The Tri Glide® Ultra is a faired batwing trike, so its amplifier install mirrors a batwing Touring bike of the same year — with one difference that matters: a trike has no saddlebag amplifier location. On any trike, weigh the extra electrical load and plan the power, ground and charging so a higher-output amplifier holds voltage under sustained use.
Why You'll Love It
- The full power range: compact amps such as the Cicada FLX500.4 and Precision Power MAA4.400 through to the FLX2000.4, plus SounDigital EVO PS and Hertz options and mono subwoofer amps to the Cicada BFA5000.1.
- Correct connection for the year: analogue high-level on pre-2014, and Boom! Box speaker-level inputs or an integration harness on the 2014 to 2025 Tri Glide Ultra.
- Four-channel, two-channel and mono: a matched amp for a front stage, a full system or a dedicated sub.
- Brands proven on Harley-Davidson Touring motorcycles: Cicada Audio, Hertz, SounDigital and Precision Power, chosen for their fit and reliability on Touring builds.
- Charging-aware selection: guidance on power, ground and charging for the added electrical load of a trike audio build.
FAQ
How does an amplifier connect on a Tri Glide?
By model year, like a two-wheel batwing. Pre-2014 uses an analogue high-level signal, and the 2014 to 2025 Tri Glide Ultra connects via the factory Boom! Box speaker-level outputs into high-level inputs, or an integration harness where required. Skyline OS and A2B arrive on the 2026 trikes, which need a compatible A2B interface first. Tell us your year and we will confirm.
Where does the amplifier mount on a Tri Glide?
Not in a saddlebag. A trike has no saddlebag amplifier location — Harley's own Trike Secondary Amplifier Installation Kit mounts under the seat on the trike frame, and aftermarket racks follow the same approach. Tell us your year and model and we'll confirm the mount for your build.
Do trikes need a charging upgrade for audio?
A trike carries extra electrical load, so a higher-output amplifier build should include a power and ground upgrade and a charging review. A lithium battery alone does not increase stator output, so plan the charging to suit the draw.
How many channels do I need?
A four-channel amp runs front and rear pairs. A two-channel runs one stereo pair, or both channels bridged into one mono load. A monoblock is for a subwoofer.
