Best Harley Audio Upgrades in Australia: Speakers, Amps, Head Units and DSP

Why Factory Harley Audio Struggles at Speed

Factory Harley-Davidson audio can sound acceptable around town, but it commonly loses clarity and usable headroom as wind, helmet and road noise rise at highway speed. It is not solved by volume alone: acoustic masking from wind and exhaust, the amount of clean power available, speaker sensitivity and source quality all contribute. Turning it up on a system that is already at its clean limit just adds distortion. This guide covers the upgrades available through MAA, organised by the problem each one solves.

How We Choose These

These are MAA selections, not an objective ranking. Where we recommend a brand or product, it is on stated criteria: real output, motorcycle-specific fitment, available impedance options, weather-suitable construction and system-matching support. Cicada features heavily because it is engineered specifically for Harley Touring fitment, but the right choice for your bike still depends on your goals and budget.

Best First Upgrade (Factory-Powered Bike)

For most riders on a factory-powered 2014-2023 bike, a matched amplifier and fairing speaker upgrade delivers the most noticeable improvement. Speakers alone on factory power leave most of their capability unrealised; the amplifier removes the power ceiling. A Cicada complete kit pairs both, pre-matched, and removes the compatibility guesswork. See Internal vs External Motorcycle Amplifiers.

Best for Highway Clarity (Speakers and Amplifier)

For clarity at speed, prioritise clean power and speaker sensitivity. Our recommendation for most amplified Harley fairing builds is Cicada Audio speakers, based on output, motorcycle-specific fitment, available impedance options and system-matching support, driven by a Cicada amplifier. Fitment splits by fairing generation:

• 2014-2023 Batwing Touring (Street Glide, Electra Glide, Ultra): direct-fit options.
• 2015-2023 Road Glide (Sharknose): Road Glide-specific fitment and grilles.
• 1998-2013 models: 5.25-inch positions, using the appropriate 5.25-inch models or a 6.5-inch upgrade with an adaptor ring.
• Redesigned CVO and 2024+ platforms: platform-specific products; confirm the exact model.

See the Cicada Motorcycle Speakers Guide and, for matching amp to speakers, How to Match Speakers and Amplifiers.

Best for Modern Connectivity (Head Unit)

The SoundStream Reserve head units cover the most common Harley platforms with model-specific fitment: wireless Apple CarPlay, Android Auto, high-brightness touchscreens, and dedicated RCA pre-outs (up to 5V depending on model) that cleanly feed an external amplifier. They use factory mounting hardware and integrate with factory handlebar controls. For touring riders, CarPlay navigation and Bluetooth hands-free are genuine safety and convenience upgrades. See Stock Harley Radio vs Aftermarket Head Units.

Best for a Factory-Radio Bike (Keep the Radio, Add a DSP Amp)

If you want to keep the factory radio and OEM look on a 2014-2023 bike, a DSP amplifier downstream corrects the factory signal and drives upgraded speakers cleanly, often more cost-effectively than a full head-unit replacement at the same performance tier. See DSP Tuning for Harley Baggers.

Best for a Skyline OS Bike (2023.5+)

On Skyline OS bikes there is no aftermarket head unit. A speaker-only swap on the factory amplification needs no interface, but adding amplification uses a compatible A2B interface (NAV-TV ZEN-H or Volunteer Audio / SeirenHD) feeding an amplifier or DSP. See Why 2023.5+ Harley Audio Upgrades Need an A2B Interface.

Best Complete DIY System (Kits)

If you want to do it once and get it right, a matched Cicada complete kit removes the guesswork. Depending on the kit, contents may include speakers, an amplifier, mounting hardware, power and signal harnesses, grilles, crossovers and, on Skyline builds, provision for an integration interface; check the exact kit contents before ordering. Components are pre-matched for impedance and power handling, and the plug-and-play harnesses are sized for factory routing, so the install is execution rather than engineering.

Best for a High-Output Build (DSP)

For a serious multi-position touring system, a DSP is what separates a good system from an exceptional one: independent EQ, crossover control and time alignment across positions. Be realistic about what it does, though: a DSP improves control and consistency, but it cannot recreate detail already lost to upstream clipping or limiting, and it performs best on a clean source. See DSP Tuning for Harley Baggers.

Budget by Stage

Cost varies widely by stage, from a focused speaker-and-amp pairing through to a full multi-zone system with DSP and, on Skyline bikes, an A2B interface. For current pricing bands by stage, see the Harley audio upgrade cost guide.
