Tri Glide Ultra Audio (2014–2025)

Audio upgrades for the 2014–2025 Harley-Davidson Tri Glide® Ultra, including the factory-amplified CVO Tri Glide. These trikes stayed on the Boom! Box radio, so a 2024 or 2025 Tri Glide does not need the A2B interface used on Skyline OS bikes.

The Tri Glide Ultra has four 5.25 inch speakers, two in the fairing and two at the rear. The 2020–2022 CVO Tri Glide is factory amplified and needs a different integration plan. Don't assume parts listed for 2024 and newer two-wheel Touring bikes will suit these trikes.

Riding a Road Glide® 3? It has its own page: Road Glide 3 Audio (2023–2025). Some parts appear in both collections because they share fitment.

Trikes are not just a Touring bike with an extra wheel.No saddlebags, and the amplifier stays in the fairing where it can, so a two-wheel parts list doesn't transfer. Tell us your model and year and we'll match it properly.Build your system →

How do you upgrade the audio on a 2014–2025 Tri Glide Ultra?

Many speakers, amplifiers and mounting solutions span multiple years within this generation, even as the factory radio changed from 6.5GT to GTS. Radio integration, factory amplification and model-specific mounting still need to be matched correctly.

Riding a Road Glide® 3? It has a sharknose fairing, a two-speaker front stage and no Tour-Pak rear position, so it is covered on its own page: Road Glide 3 Audio (2023–2025). Some parts still appear in both places because they share fitment with the Tri Glide Ultra.

FAQ

Does a 2024 or 2025 Tri Glide need an A2B interface?

No. The 2024 and 2025 Tri Glide Ultra remained on the Boom! Box GTS platform and did not receive Skyline OS. A2B integration does not apply to these bikes. Skyline OS and A2B arrive in the trike range with the redesigned 2026 models.

Are 2014–2025 Tri Glide Ultra speaker upgrades the same?

The standard Tri Glide Ultra kept the same basic four-speaker layout across this period, with two 5.25-inch speakers in the fairing and two at the rear. That gives strong parts commonality across the run, but radio integration and factory-amplified CVO models still need to be checked separately.

What is different about the CVO Tri Glide?

The 2020–2022 CVO Tri Glide was factory amplified and used a higher-spec audio system than the standard Tri Glide Ultra. That means an upgrade is not simply a matter of treating it like a radio-powered four-speaker bike. The factory amplifier, speaker configuration and signal path all need to be considered when planning the replacement system.

Why do some Road Glide 3 parts show here?

The 2023–2025 Road Glide 3 shares fitment with the Tri Glide Ultra on a number of front-stage parts, so those products appear in both collections. Its factory layout is different: a two-speaker sharknose front stage and no Tour-Pak rear position, so Tour-Pak and saddlebag parts from other Touring builds do not automatically apply. Start from the Road Glide 3 audio page if that is your bike.

Where does an amplifier mount on a Harley trike?

In the fairing where possible. A compact amplifier usually fits there, while a bigger system with more channels or a subwoofer may need another location. Tell us your year, model and planned system and we'll confirm the mounting before you order.

Why isn't the Freewheeler included in the normal audio fitment?

The Freewheeler does not use the factory fairing and infotainment system fitted to the Tri Glide Ultra and Road Glide 3. Audio upgrades on a Freewheeler are therefore planned as a more custom build rather than following the same speaker and integration path as the factory-audio trikes in this collection.

Not sure what fits? Tell us your year, model and current audio setup and we'll confirm the parts before you order, or contact Motorcycle Audio Australia.
