No Sound from Car Speakers? Common Causes, Fixes

Start With the Most Overlooked Causes

Many cases of car audio not working are caused by incorrect system settings rather than component failure. Modern infotainment systems found in vehicles across Melbourne’s metro area can easily reroute audio without the driver realising.

Check the following first:

• Volume and mute settings

• Correct audio source selected

• Balance and fade not set fully to one side

• Bluetooth audio routed to another device

If there is no sound across all sources, the problem is likely electrical or hardware-related.

Blown Fuses and Power Supply Issues

A blown audio fuse is one of the most common reasons customers visit us for car speaker repair in Melbourne. Vehicles often have multiple fuses linked to the stereo, infotainment and amplifier.

Signs of fuse-related issues include:

• Head unit powers on but no audio

• Sound stops suddenly while driving

• Fuse blows again after replacement

Repeated fuse failure often points to wiring or amplifier faults and should be inspected by a qualified car audio installer in Melbourne. Contact Us.

Wiring Problems and Loose Connections

Damaged or loose wiring is a frequent cause of intermittent or complete speaker failure, especially in door speakers.

Common wiring issues we see across Melbourne suburbs:

• Broken wires in door looms

• Corroded speaker connectors

• Poor-quality aftermarket wiring

• Previous installs done without OEM integration

Vehicles that have had audio work done elsewhere often develop wiring faults over time.

Head Unit or Amplifier Failure

When all speakers stop working at once, the fault is often traced to the head unit or factory amplifier. This is especially common in European and prestige vehicles serviced around Melbourne’s inner and northern suburbs.

Typical indicators include:

• No sound from any speaker

• Screen works but audio does not

• Partial speaker output

• Audio cuts in and out

Factory systems such as Harman Kardon or Bose are particularly sensitive and require specialist diagnosis.

Blown or Damaged Speakers

Speakers themselves can fail due to age, excessive volume or long-term vibration, especially in vehicles used for daily commuting around Melbourne.

Signs of speaker damage:

• No sound from specific doors

• Crackling or buzzing noises

• Distorted sound at low volume

• Complete silence from one side of the car

Proper testing usually requires professional equipment.

Problems After Apple CarPlay or Android Auto Installation

We regularly see customers from Melbourne, Essendon, Airport West and surrounding areas experiencing no sound after Apple CarPlay or Android Auto installation.

Common causes include:

• Incorrect factory amplifier integration

• Wrong interface for the vehicle

• Signal routing errors

• Poor grounding during installation

Professional integration is critical in modern vehicles to retain factory audio performance.

What You Can Safely Try Yourself

Before booking a car audio repair in Melbourne, you can try a few basic checks.

Safe DIY steps include:

• Restarting the infotainment system

• Re-pairing Bluetooth devices

• Checking audio-related fuses

• Switching between audio sources

If sound does not return, professional diagnosis is recommended.

Why Professional Diagnosis Matters

With no sound from car speakers, multiple faults can present identical symptoms. Guesswork often leads to wasted time and money.

• Identify the exact fault quickly

• Avoid unnecessary part replacement

• Protect factory electronics
