Questions & answers
Car audio in Singapore, answered plainly
Everything customers ask us before booking — pricing, what a DSP actually does, how long a fit takes, and what happens to your vehicle warranty.
Pricing & packages
How much does a car audio system cost in Singapore?
At Han Revolution, complete car audio packages start at $788 for Bronze and go up to $3,688 for Titanium. Every price includes professional installation and in-house sound tuning, so there is no separate fitting fee. The mid-range Gold package at $1,588 is the most popular because it is the first tier with a DSP amplifier.
Why does professional installation cost more than buying speakers online?
The speaker is maybe half of what you are paying for. The rest is the fabrication that holds it properly, sound deadening so the door stops resonating, wiring that will not buzz in two years, and the tuning that makes the whole thing sit right in your car. A good speaker fitted badly sounds worse than a modest one fitted well — which is why we quote installation and tuning inside the package price rather than as extras.
Can I upgrade one part at a time instead of buying a whole package?
Yes. The six packages are the best value at each price level, but nothing stops you starting with a front stage and adding an amplifier or subwoofer later. Tell us where you want to end up and we will sequence it so nothing you buy now has to be thrown away later.
What is the cheapest upgrade that actually makes a difference?
The Bronze package at $788. Replacing the factory front speakers and adding a compact active subwoofer is the single biggest jump most drivers will ever hear, because factory speakers are the weakest part of almost every car. Anything cheaper tends to be a speaker swap with no tuning, which rarely sounds as different as people hope.
Is installation included in the price?
Yes. All six Han Revolution package prices include professional installation and sound tuning at our Ang Mo Kio workshop. What is quoted is what you pay.
Do you offer instalment plans?
Payment options vary — we accept cash, NETS, PayNow and major credit cards. If you would like to discuss instalments, call or WhatsApp +65 8298 2360 and we will tell you what is currently available.
Why are your package prices lower than the usual price shown?
The usual price reflects the components bought individually plus standard fitting. Because we buy these combinations in volume and fit them regularly, we can package them at a lower total. The savings range from $206 on Silver up to $564 on Titanium.
Choosing a system
Which car audio package is best for me?
Start with your music. Bronze and Silver suit EDM and party music where you want volume without distortion. Gold is the pick for bass-heavy listening because its DSP lets us control low frequencies properly. Platinum, Diamond and Titanium are built for vocal clarity and soundstage accuracy. The fastest way to decide is a free demo.
What is the difference between component and coaxial speakers?
A coaxial has the tweeter mounted in the middle of the woofer, so it is one unit and drops straight into the factory hole. A component system splits them: the tweeter mounts high, usually on the A-pillar or door top, and the woofer stays low in the door. Separating them is what lifts the sound up to the windscreen instead of leaving it around your knees, which is why every one of our packages uses components at the front.
Do I really need an amplifier?
Not to make sound, but usually to make good sound. A factory head unit puts out roughly 15–20 watts per channel, and it is straining near the top of that. An amplifier gives the speakers clean power so they stay composed when you turn it up, rather than getting harsh. It also lets a DSP do its work. Bronze and Silver run without one; Gold and above include it.
Do I need a subwoofer if I don't listen to bass-heavy music?
Most people are surprised by this one — yes, usually. A subwoofer is not about making a car boom. It takes the lowest notes off your door speakers so they can concentrate on the midrange, which is where voices and instruments live. Vocal and acoustic listeners often notice the improvement more than bass listeners do, because the midrange cleans up.
What is a soundstage, and why does everyone talk about it?
It is where the music appears to be coming from. In a badly set up car, the singer sounds like they are in the door next to you, because that speaker is closer to your ear. Properly tuned with time alignment, the voice sits centred on the windscreen ahead of you, roughly where it would be at a live performance. It is the difference most people hear first in our testing room, and it costs nothing extra — it is tuning, not hardware.
Why do factory car speakers sound flat even in an expensive car?
Carmakers build to a budget and a weight target. Factory speakers usually use paper or thin polymer cones and small magnets, driven by a low-power head unit, in a door that was never sealed as a speaker enclosure. Even premium badged systems are often the same drivers with more equalisation. The car is not the problem — the speakers and the tuning are.
What does a DSP actually do?
A DSP — digital signal processor — lets us control timing, crossover points and equalisation per speaker. In a car you sit off-centre, so sound from the near speaker arrives before the far one and the stereo image collapses toward your door. Time alignment delays the near speaker by milliseconds so both arrive together, which pulls the soundstage up onto the windscreen. Gold and above include a DSP.
Do I need to replace my head unit?
Usually not. Modern amplifiers and DSPs accept high-level inputs, so we can tap the factory head unit's speaker outputs and keep your original screen, steering controls and reversing camera working. If your car has an amplified or fibre-optic factory system we will check compatibility before quoting.
Will a subwoofer take up my whole boot?
Not with the packages we build. Every package uses a compact active subwoofer — the slimmest is 290 × 210 × 65 mm, roughly the footprint of a laptop. Most fit under a seat or against a boot wall, leaving usable luggage space.
Installation & aftercare
How long does a car audio installation take?
Most speaker and subwoofer packages are done within one working day. Builds with a DSP amplifier need extra tuning time, so we usually ask for the car for a full day. We confirm the duration when you book.
Will a new sound system drain my car battery?
Not with a system sized correctly for the car. Our packages draw power only while playing, and modern amplifiers switch to standby with the ignition. If you regularly sit with the engine off and the music on, tell us when you book — that changes what we recommend.
Will installing it damage my door panels or interior?
No. We use vehicle-specific harnesses and the factory mounting points wherever they exist, so panels come off and go back on the way the manufacturer intended. Where a custom mount is needed — an A-pillar tweeter pod, for example — it is built to fit the trim rather than cut into it.
Can I move the system to my next car?
Usually a good part of it. Amplifiers, subwoofers and processors move over easily. Speakers depend on whether the sizes and mounting depths match the new car. Tell us when you are thinking of changing cars and we will fit it in a way that comes out cleanly.
Does the system need any maintenance?
Almost none. Keep the volume below the point where it distorts, since that is what kills speakers rather than loudness itself, and give new speakers a few weeks of normal listening to loosen up. Come back for a free re-tune after that — your ears will have adjusted and what sounded right on day one often is not what you want by week three.
Will upgrading my car audio void my vehicle warranty?
A properly installed audio system should not void your vehicle warranty. We use vehicle-specific harnesses and non-destructive mounting wherever possible, so the original wiring stays intact and the work can be reversed if you sell the car.
Do you provide a warranty?
Yes — one year on every installation, on top of whatever manufacturer warranty applies to the components. If something rattles, buzzes or drops out, bring the car back.
Can I come back to have the system re-tuned?
Yes, and we encourage it. Your ears adjust over the first week or two, and what sounded bright on day one often sounds right by day ten — or the other way round. Bring the car back and we will fine-tune it.
Can you re-tune a system installed by another shop?
If your amplifier or processor is DSP-capable, yes. Call us with your equipment list and we will tell you honestly what improvement is realistic before you drive down.

Yes — Japanese, Korean, European and Chinese makes, including hybrids and EVs. If your model needs a special adaptor or harness we will tell you before you commit.
Electric cars & Tesla
Can you upgrade the audio in an electric car?
Yes, and EVs are some of the best cars to do it in. Without engine noise masking the detail, a good system is far more obvious than in a petrol car. We work on Teslas regularly and stock plug-and-play kits for the Model 3 and Model Y, including the Juniper and Highland refreshes — see our Tesla page for what we fit.
Will a sound system reduce my EV's range?
Not in any way you will notice. A car audio system draws a tiny fraction of what the motors use — the climate control has a far bigger effect on range than the stereo does.
Why does road noise seem louder in an electric car?
Because there is no engine covering it. In a petrol car, engine and exhaust noise masks tyre and wind noise; remove that and what is left becomes obvious. Sound deadening on the doors and floor is often the single most worthwhile thing you can do to an EV, and it makes the audio system sound better at the same time.
Do Tesla audio upgrades work with the factory screen?
Yes. Our Tesla installs keep the original screen, controls and interface — the amplifier and processor sit behind the factory system using high-level inputs, so nothing about how you use the car changes. The same applies to the CarPlay module, which runs inside the Tesla interface rather than replacing it.
Will an audio upgrade void my Tesla warranty?
A properly installed system should not. We use plug-and-play harnesses and do not cut factory wiring, so the work can be reversed. That said, warranty terms are between you and the manufacturer — if you are still under warranty and want certainty, ask us to walk you through exactly what the install touches before you commit.
In Singapore
Does a car audio system affect my car's resale value?
A tidy, professionally installed system is usually neutral to slightly positive, and the equipment itself holds value if you take it with you. What hurts resale is visible butchery — cut panels, exposed wiring, holes in the boot floor. That is a good reason to have it done properly the first time.
Should I tell my insurer about a car audio upgrade?
Yes, we would recommend it. Most policies ask you to declare modifications, and an undeclared system may not be covered if the car is stolen or damaged. Insurers differ, so check your own policy — it is usually a short call, and having it declared means the equipment is actually insured.
Does Singapore's humidity affect car speakers?
It affects cheap ones. Paper cones and untreated foam surrounds can soften or delaminate in constant high humidity, especially in a car that sits in the sun. The brands we carry use treated or synthetic materials built for exactly this, which is part of why they cost what they do. Parking in the shade and running the aircon before blasting the system on a hot day helps any system last longer.
