Top 9 Things Causing Very Low Sound From Stereo Speakers


A stereo amp is used to play sound, music, and other audio. With its settings, you can adjust the volume of the speaker.

But what if there is a very low sound from stereo speakers? Worry no more because, unlike other sites, this post will help you to fix this problem with your stereo system.

What are the causes of the stereo receiver not producing sound?

Does your stereo receiver not produce high-end sound? Silent sound speakers can be caused by the following:

  1. Faulty or disconnected speaker wires
  2. Low voltage signals
  3. Wrong input source selection
  4. Malfunctioning source component
  5. Distortion from a faulty input signal
  6. Broken speakers
  7. Loose connections
  8. Bad ground from the power amp
  9. Anti-theft protection mode is on

If you want to fix a defective stereo receiver that doesn’t produce sound, you should isolate first the problem. So, you can get the best possible solution.

In troubleshooting a defective stereo receiver, make sure you turn off the power to the components before disconnecting or connecting wires and cables. You can turn on the power button after every step to verify the right operation.

How to fix low volume from your connected speakers?

In case your sound system produces a very low volume, you can consider the following solutions.

  1. Verify if your speakers have been properly connected to their A/V receiver. Is the A/B speaker setup set to its position? If your speakers are connected to A speaker connections on the rear of the A/V receiver, the A/B signal should be set to the A position.
  2. Check the input function, including FM and AM, so you can determine that you’re not getting the low audio through the inputs of your head unit.
  3. Check if the A/V receiver is not set to MUTE.
  4. Conduct the test tone function if it’s applicable for your A/V receiver model.
  5. Try setting your A/V receiver into a different surround sound mode.
  6. Verify if the A/V receiver was set to surround sound mode.
  7. You can also try to increase the volume level.
  8. Change the TV+AMP setting on the receiver into AMP.
  9. Revise that there are no headphones connected to its A/V receiver.
  10. You can also try replacing the wires.
  11. Try to replace them with a different set of speakers.
  12. Low volume can also be due to another component connected to one of the input sources like a television or Set-top Box (STB).
  13. Verify the connection between the source and the A/V receiver to ensure they’re securely connected.
  14. Try another input jack to eliminate issues with the existing jack being used. In case the audio is sent from STB or TV to the A/V receiver, you may disable the internal speakers from the input source.
  15. You can also set the audio output of the TV to VARIABLE or FIXED. If the audio output of the TV is set to VARIABLE, you can increase the TV’s volume level.
  16. You can try another source like a CD player to check if the volume is low on all sources or only the one that you are currently using.

What if there’s very low or no sound from one of the speakers?

Can you hear a very low volume from one of the speakers? Does your stereo system has no sound? You can try the following tips to find the possible solution for your audio system issue.

  • Verify that the radio’s speaker balance is set in the center position.
  • Make sure the speaker cables are connected correctly to the rear of your car radio. If the problem is not yet resolved, you can replace them.
  • If the issue is not yet resolved, you can remove the speaker connections from your radio.
  • Then, you can connect the right to the left input on your receivers.

How to fix a stereo receiver that doesn’t produce sound?

Verify the power

Revise that plugs are seated securely in specific sockets. Thus, a plug might slip out halfway at times, failing to draw power. Ensure that wall switches that operate on outlets are turned on.

Verify if all devices, like a surge protector or power strips, can be turned on. In case it doesn’t flip on, you can start testing it with a different outlet to identify if it functions properly.

Check your speaker wires

Test and inspect the wires leading from the amplifier/receiver to your speakers. You should also pay attention to loose or damaged connections.

Most people forget to check the bare ends to know if adequate insulation is stripped off. Verify if the speaker wire connectors are installed properly and they are not causing the volume control problem.

Most receivers come with a Speaker B switch to add more speakers. You should check if the right ones are enabled and see if the proper source was chosen.

Connect speakers properly

You can connect your speakers to different working audio sources to check if they still function correctly. If they don’t play, they can be defective or damaged.

On the other hand, if they play, you can reconnect them to the car or home audio device and continue. The common problem is that sometimes the banana plugs become loose. You can try to tighten them or use a different connection.

Verify the input source components

Start by testing if the source component you’re using includes a Blu-ray /DVD player, laptop, RCA line input, Television, CD player, or turntable with a different working set of speakers.

If it doesn’t properly play, the problem can be on the device. If all source components are in good condition, you can connect them to the original receiver. Then, set them to play input. Toggle through every input source on the receiver individually.

Suppose the receiver functions with some input sources, but not others, the cables which connect the component to the receiver can be the culprit for the low volume or lack of sound. Change the suspect cables and use the original component.

Last note: The right wires can produce louder output sounds.
