How to Fix a Car Speaker that’s Not Working on One Side?

It may seem daunting at first, but with a little patience and some basic tools, you can get your speakers working like new again. Let’s get started!

Reasons Behind Car Speaker Not Working on One Side

There are a few common issues that cause car speakers to stop working on one side. Read on to learn the reasons along with the ways to fix-

Stereo Settings Issue

The first thing you should check is your car stereo’s settings. If the balance is set to favor one side, it can cause the other side to sound quieter or even muted.

To fix this, simply adjust the balance until both sides are equal. You will find the settings in your stereo menu, typically in equalizer or sound settings.

More than half of the one-side-not-working issues are not an issue, just the incorrect stereo settings that cause some of the speakers to not work.

Blown Fuses

Another common issue is a blown fuse. Fuses protect your car’s electrical system from shorts and overloads, so if one has blown, it can affect your speakers.

To check if this is the case, locate your car’s fuse box and look for a blown fuse. If you find one, replace it with a new one of the same amperage.

However, this issue isn’t likely to cause one part of the system to work and another part to not work. Fuse blowouts typically result in the whole system to stop working.

But we never know what car model you have and if that has any separate fuse for different sides of the speakers.

Since checking the fuses won’t hurt, I recommend eliminating every minor possibility before you look into the bigger issues.

Loose or Damaged Wires

Over time, wires can become loose due to vibrations from driving or bumps in the road. This can cause the connection to become intermittent, which will result in sound problems.

To fix this, simply locate the affected wires and tighten them.

If they are damaged, you will need to cut out the damaged section and splice in a new piece of wire.

Loose or damaged wires can easily be fixed with a little patience and some basic tools.

If you don’t feel comfortable doing this yourself, you can always take it to a professional to have it done.

Wrong Speaker Polarity

Another issue that can cause sound problems is the wrong speaker polarity. This happens when the positive and negative terminals on your speakers are reversed.

To fix this, simply switch the wires around so that the positive and negative terminals are in the correct positions.

This is a quick and easy fix that can be done in a matter of seconds.

Amplifier Malfunction

If you have an amplifier, it could be the cause of your sound problems. Amplifiers can fail for several reasons, so if you suspect that this is the case, you may need to take it to a professional to have it checked out.

Most of the time, one channel remains good while the other goes bad causing the speakers of that channel to not produce any sound.

You can check whether this is the case by swapping out the cables of the channels. For example, if speakers of channel 1 are not working and speakers of channel 2 are working. Try connecting channel 1 RCA cable to channel 2 and check whether the speakers produce sound now.

If they start producing sound after the swap, it’s the amplifier that’s causing the issue.

While amplifier failure is not as common as some of the other issues on this list, it can still be the cause of your sound problems. So, definitely check this.

Speaker Gone Bad

If you’ve ruled out all of the other possible issues, then it’s likely that your speaker has gone bad. This is usually the case if only one speaker is not working.

In this case, you will need to replace the affected speaker with a new one.

You can buy replacement speakers at most electronics stores or online.

Once you have your new speaker, simply remove the old one and install the new one in its place.

And there you have it!

To Conclude

If your car speaker is not working on one side, the most likely cause is a blown fuse, loose or damaged wires, wrong speaker polarity, amplifier malfunction, or a bad speaker.

Most of these issues can be fixed fairly easily with some basic tools and patience.

However, if you don’t feel comfortable doing this yourself, you can always take it to a professional to have it done. Thanks for reading! I hope this helped!
