Designed and tuned for real performance at highway speed.
At Motorcycle Audio Australia, we design, build and tune complete motorcycle audio systems around how you actually ride — not how a bike sounds sitting in a garage with the engine off.
Most motorcycle audio systems are never properly tuned — and more power just makes the problem louder.
Most custom builds fall between $3,000 and $10,000+, depending on scope.
If you want real clarity, proper balance and usable mid-bass at highway speed — you’re in the right place.
Two things quietly limit most motorcycle audio systems, and neither of them is power.
A large percentage of bikes that come through a shop have at least one speaker out of phase. That single issue kills mid-bass, reduces output and leaves the whole system sounding flat. Too often, the response is to throw a bigger amplifier or larger speakers at it.
Even a small difference in speaker placement can create phasing problems that waste hours in guesswork. Without the right measurement tools, many of these issues stay hidden. At tweeter level, even trained ears can struggle to pick them up reliably without proper testing.
Then there is enclosure behaviour. A stock saddlebag only gives you a limited amount of usable airspace. That affects what frequencies the bag can physically produce. No speaker swap changes enclosure physics. The bag decides what is possible.
We do not guess. We measure, verify and tune to the numbers. That is why our builds deliver the clarity and mid-bass most systems promise but never actually produce.
We offer proven upgrade packages, but custom builds are for riders who want something engineered specifically around their bike, their goals and the way they ride.
Full system builds — head unit, amplifiers, speakers, DSP, wiring and integration designed as one complete system
Speaker and amplifier upgrades — matched components selected for your fairing, lids and bags
DSP integration and tuning — proper signal processing, time alignment and EQ verified with measurement tools
Subwoofer and bass systems — saddlebag woofers and low-end reinforcement engineered around real enclosure behaviour, not just wattage claims
Fairing and lid modifications — custom mounting, speaker adapters and enclosure work for proper fit and output
Electrical and wiring upgrades — clean power, correct cable sizing, proper grounding and connectors matched to the load
Tuning and wire rescues — diagnosis, retuning and correction of existing systems, including work completed by other shops
Every build follows a structured process so nothing is left to chance.
It starts on paper, not in the workshop. We talk through your bike, how you ride, what you listen to and what you want the system to do. We also have a demo bike available, so you can hear what a properly built and tuned motorcycle audio system actually sounds like before committing.
We design the full system as a package — speakers, amplifiers, DSP, wiring and power — so every part works together. No mismatched components, no bottlenecks and no wasted spend. If a less expensive component performs better in your application, that is what we recommend. We would rather put the budget where it actually changes the result. We are also happy to work with the factory radio where it makes sense. A properly configured OEM head unit paired with a DSP can still deliver excellent results. Aftermarket head units offer more features, but they can add up quickly. If the factory source gets you where you need to be, we would rather invest the budget in the parts that most improve what you hear.
Proper mounting, clean wiring, solid grounding and careful integration with the platform of your bike all matter. Shortcuts here are one of the biggest causes of noise, reliability issues and premature failure. Where adaptor harnesses are available, that is what we use. We do not like cutting into factory harnesses unnecessarily. It keeps the install cleaner, makes future servicing easier and helps protect the value of the bike.
DSP is not optional here. It is part of every build. You would not build a performance engine with quality parts and then skip the dyno tune. Audio is no different. Without DSP, you cannot properly control crossover points, phase behaviour or speaker protection. Depending on the application, we use either an amplifier with DSP built in or a standalone external DSP. We verify phase across every driver, check for cancellations, set time alignment, tune crossover points from actual response data and EQ the system so it works at speed — not just at idle in the bay.
Before handover, every build goes through a proper shakedown. The finished bike runs as our shop system for the day. We want it playing hard, for hours, in our hands. If something is going to fail, we want it to happen here — not 200 kilometres down the road.
You get a full walkthrough of the system — what was done, why it was done and how to get the best out of it without pushing it beyond its limits. The final tune is done with your phone connected to your bike, not ours. Different devices output differently, and the system should be dialled in around what you will actually use on the road.
Seven things that shape every build we take on.
You can buy speakers and amplifiers anywhere. What you cannot buy off the shelf is a system where every part has been selected, installed and tuned to work together toward a real result.
Phase, time alignment, frequency response and signal analysis are not optional extras. They are what separate a system that sounds good in the driveway from one that performs properly at 110 km/h.
If a less expensive part performs better in your application, that is what goes in. We are not here to pad out a parts list. We are here to build the right system.
Motorcycles live outside. They deal with vibration, weather and heat. Every component we use is selected with real-world durability in mind.
Correct cable sizing, proper grounding and connectors rated for the actual load all matter. Cheap wiring decisions quietly destroy both performance and reliability.
Our builds come with proper warranty support. If something is not right, we sort it out.
We understand Harley-Davidson wiring, CAN bus, Boom Box and Skyline OS platforms, along with the model-specific quirks that trip up general audio shops. We know what fits, what does not and where the common problems hide.
What it is like to bring a bike to us.
Whether you are dropping the bike off in person or shipping it in, you are welcome in the workshop. We will walk you through the build process, show you the tools and explain the reasoning behind the system design.
We take pride in keeping the shop clean, organised and professional — because if you are trusting us with a serious bike and a serious build, the workshop should reflect that standard.
We primarily build for:
Harley-Davidson Touring — Street Glide, Road Glide, Ultra and Trike
2024+ Touring — Skyline OS / A2B platform
Selected Indian models
If you already have an audio setup that does not sound right — or one installed elsewhere that was never properly tuned — we offer standalone tuning and diagnostic work.
That includes phase correction, signal analysis, crossover adjustment and wiring rescue work. We will assess what is there, tell you what is actually wrong and fix it.
How custom work is quoted, scheduled and handled.
We only take on a limited number of custom builds at a time so quality stays high.
If you want a system that actually delivers at speed — not just in the garage — tell us about your bike, your goals and how you ride.
