5 Easy Fix for Rear Car Speakers Not Working

There are few things more frustrating than getting into your car, turning on the radio, and only hearing sound coming from the front speakers.

If your rear car speakers have stopped working, there are a few potential causes and solutions.

In this post, we’ll walk you through a few of the most common reasons why your rear car speakers might not be working and what you can do to fix the problem.

Why is there no sound from my rear speakers?

If you’re not getting any sound from your rear speakers, there are a few possible explanations.

1. Volume is low

First, check to see if the volume for the rear speakers is too low. If it is, adjust the volume levels until you can hear the sound coming from the rear speakers.

2. Cables are not connected

Another possibility is that the audio cables are not properly connected. Check to see if the cables are plugged in securely at both ends. If they are, try disconnecting and then reconnecting them to see if that solves the problem.

3. Speakers are defective

Finally, it’s possible that the rear speakers themselves are defective. If none of the other solutions work, you may need to replace the rear speakers.

How to fix Rear car speakers not working issue?

1. Check the Fuses

If your rear car speakers are not working, the first thing you should check is the fuse. Oftentimes, a blown fuse is the root cause of the problem.

To check if the fuse is blown, locate the fuse box in your car and remove the fuse for the rear speakers.

Inspect the fuse to see if it is burned out or damaged in any way. If it is, replace it with a new fuse of the same amperage and size.

Once you’ve replaced the fuse, turn on your radio to see if sound is now coming from your rear speakers.

2. Check for Loose Wires

If checking and replacing the fuse doesn’t solve the problem, the next step is to check for loose wires. Over time, vibrations from driving can cause wires to become loose or disconnected.

To check for loose wires, start by disconnecting your car’s battery. Then, remove the panels around your rear speakers so you can access them.

Once you have access to your rear speakers, inspect all of the wires to see if any are loose or disconnected. If you find any loose or disconnected wires, reconnect them and secure them so they won’t become loose again.

Once you’ve checked and tightened all of the wires, reconnect your battery and turn on your radio to see if sound is now coming from your rear speakers.

3. Check for a Bad Ground

Another potential reason why your rear car speakers might not be working is a bad ground connection.

• To check for a bad ground connection, start by disconnecting your car’s battery.
• Then, remove the panels around your rear speakers so you can access them. Once you have access to your rear speakers, locate the ground wire and disconnect it from the speaker terminals.
• Next, use a multimeter to test continuity between the ground wire and a known good ground point on your car (such as a metal part of the chassis).
• If there is no continuity or if resistance is greater than 0 ohms, that means there is a bad ground connection somewhere between your rear speaker and a known good ground point on your car.

To fix this problem, you’ll need to trace back along the path of the ground wire until you find where it has come disconnected or has developed high resistance and then reconnect or repair it as necessary.

Once you’ve fixed the problem with the ground wire, reconnect your battery and turn on your radio to see if sound is now coming from your rear speakers.

4. Make sure amplifiers are working

Many times when people have rear car speakers that are not working, they automatically assume that the problem is with the speakers themselves. However, in many cases the issue is actually with the amplifier.

The amplifier is what provides power to the speakers, and if it is not functioning properly then the speakers will not work correctly either. There are a few signs that you can look for to determine if your amplifier is the issue.

First, check to see if all of the speakers are not working or just the rear ones. If it is just the rear ones, then chances are good that the amplifier is to blame.

Another sign is if you hear a popping or crackling sound coming from the speakers. This is often caused by a loose connection between the amplifier and the speakers.

5. Make Sure the Problem is Not from the Head Unit

The head unit is the control center for your audio system, and if it is not working properly, it can cause all sorts of problems.

In particular, make sure that the head unit is turned on and that the volume is turned up.

If the head unit seems to be working properly, then the next step is to check the speakers themselves.

How to Diagnose Blown Car Speakers?

Car speakers can blow for a number of reasons. The most common reason is usually due to too much power being sent to the speaker.

In any case, it’s important to diagnose the problem so you can fix it and prevent it from happening again in the future.

Step 1: Disconnect the speaker

The first step is to disconnect the speaker from the power source.

If you’re not sure which wire is connected to the speaker, consult your car’s owner manual. Once the speaker is disconnected, you can proceed to the next step.

Step 2: Check the speaker for vibration

Next, you’ll want to check the speaker for vibration. To do this, you’ll need to hold the speaker up to your ear and tap on it with your finger.

If you hear a rattling noise, that means there’s definitely something wrong with the speaker.

However, if you don’t hear anything, it’s possible that the problem isn’t with the speaker itself but with the amplifier or wiring.

Step 3: Check the speaker with a multimeter

To be absolutely sure that the problem lies with the speaker and not elsewhere, you’ll need to check it with a multimeter.

Set your multimeter to ohms and touch one of the leads to each of the terminals on the back of the speaker.

If there’s no continuity between the two terminals, that means that there’s an open circuit and therefore the speaker is blown.

Step 4: Determine the amount of damage to the speaker

Once you’ve determined that the problem lies with the speaker, you’ll need to assess how much damage has been done.

If only one terminal is damaged, you may be able to solder it back onto the speaker.

However, if both terminals are damaged or if there’s any other visible damage to the speaker itself, it will need to be replaced entirely.

Conclusion

If your rear car speakers have stopped working, there are a few potential causes and solutions.

In this blog post, we’ve walked you through few of the most common reasons why this problem occurs and what you can do to fix it.

By following these steps, you should be able to get sound coming from your rear speakers once again in no time!
