How To Fix A Car Speaker With No Sound? 3 Simple Steps

Imagine going downtown, and suddenly, your radio system is moody and breaking down. As you check, though there’s still power, the car speaker does not make any sound. What should you do?

Should you check the head unit or the wire first? Here are steps to fix a car speaker with no sound.

How Does A Car Radio Work?

Many people believe “theory must square with practice”. So, knowing the car stereo structure and how it works will help you quickly find the key for your unlocked door.

There are four main components of the car speaker:

  • The head unit is the speaker’s body, a combination of controls, dials, or touchscreen. Like any electrical device, the head unit also has hardware and software, which are essential for file reading, USB, AUX, Bluetooth connections, or even volume controls.
  • The amplifier is a general term for a circuit that generates an amplified version of its input signal. For speaker usage, its amplification turns the low signal from the head unit to power the sound of the speaker louder.
  • Speakers take the signal from the amplifier to generate a sound wave that our ears pick up and experience as sound.
  • Wiring is cabling and connected to the body to the antenna, the amp, and the car battery of speakers.

When the car stereo systems have no sound coming out of the speakers, the issue is usually blown a fuse, likely followed by loose wiring and amplifier; lastly, check for other problems such as software.

Inspect The Fuses

The automobile fuse protects the specifics of utilizing electricity by preventing fire, explosion, and damage.

As a result, this gear is equivalent to a vehicle’s “bodyguard,” which protects the wires, connectors, and all the audio equipment. When the fuse is blown, the circuit gets disconnected for safety reasons.

So, a broken fuse can indeed interrupt your joy of listening to quality music.

When dealing with an electrical problem, you should always check the fuse box first. The fuse is usually located in the back of the stereo system.

After finding where it has been located, you can use the test lamp to examine if it is still working. Another method is plugging each fuse to see if the wire is cracked.

What If The Amplifier Wires Are Loosened?

The amplifier is noticeably placed at the back of the vehicle. Like the head unit, the amplifier has a multitude of wires in and out connected to the speakers.

You also need to go through the rest of them consciously to determine whether the wires are loosened or if they could be unintentionally left disunited.

What If The Error Is From The Speaker’s Cables?

The final checkup is for speakers. It is usually not the check destination because it could not shut down the whole system, but for a single speaker, it may be troublesome.

Then, use your ear to find the rest and inspect the broken one while you open the speaker cover with forethought and check the wires.

Amplifier Is Failing

Because the amplifier is responsible for bringing a stereo signal for the speaker to make sound, it is the cause of “muting” the speakers when they crash.

In this case, you must bypass the amp and remove it from the system. It indicates that later if any devices are faulty in the chain, it will cause a malfunction.

However, when the radio has no power or fixing the amp won’t work, you should check for the battery or the head unit.
