Speakers are an integral part of any audio system, allowing us to enjoy music, movies, and games. Unfortunately, like any other electronic device, speakers can break down and stop working. A common issue is a blown speaker, which can be caused by a variety of issues. In this article, we will discuss how to troubleshoot and fix a blown speaker.

What Causes a Blown Speaker?

A blown speaker is usually caused by either a faulty amplifier or incorrect wiring. If an amplifier is too powerful for the speaker, it will send too much power to the speaker, which can cause it to overheat and eventually blow. Additionally, incorrect wiring can cause a speaker to be overloaded, resulting in a blown speaker.

How To Diagnose a Blown Speaker

If you suspect that your speaker is blown, the first step is to diagnose the problem. The easiest way to do this is to use a multimeter. The multimeter will allow you to measure the resistance of the speaker and determine if it is functioning properly. If the speaker has a low resistance, then it is likely that it is blown.

Replacing a Blown Speaker

Once you have determined that the speaker is indeed blown, the next step is to replace it. The first step is to find a suitable replacement speaker. You can either purchase a new speaker or try to find a used one. Make sure that the new speaker is compatible with your amplifier and wiring.

Wiring the New Speaker

Once you have the new speaker, the next step is to wire it up. Make sure that all the cables are properly connected and that the amplifier is set to the correct settings. If you are unsure about how to wire the speaker, consult a professional.

Amplifier Settings for the New Speaker

Once the new speaker is wired up, the next step is to adjust the amplifier settings. Make sure that the amplifier is not sending too much power to the speaker. If the amplifier is set to an incorrect setting, it can cause the speaker to blow again.

Checking the Speaker

Once the new speaker is wired up and the amplifier settings are adjusted, it is time to test the speaker. This can be done by playing music through the system and listening for any distortions or issues. If the speaker sounds good, then the repair is complete.

Troubleshooting Tips

If you are having trouble fixing a blown speaker, there are a few troubleshooting tips that can help. First, make sure that the amplifier settings are correct. Additionally, check the wiring to make sure that all the connections are secure. Finally, if the speaker is still blown, you may need to replace it.


In conclusion, fixing a blown speaker can be a tricky endeavor. However, with the right knowledge and tools, it is possible to troubleshoot and repair the speaker. Make sure to use the right amplifier settings and check the wiring to ensure a successful repair.
