What Causes a Subwoofer to Blow?
There are a few things that can cause your subwoofer to blow. The most common cause is playing it too loud for too long. This can cause the voice coil to overheat and eventually burn out. Another common cause is a short circuit in the subwoofer’s electrical system. This can happen if the subwoofer is damaged or if it’s not properly wired.
Additionally, using an amplifier that’s too powerful for the subwoofer can also cause it to blow. Another common cause of blown subwoofers is using the wrong type of amplifier. If you’re using a home theater receiver to power your subwoofer, ensure it’s rated for use with subwoofers. Finally, using the wrong type of speaker wire can also cause your subwoofer to blow.
Some Effective Ways on How to Fix a Blown Subwoofer
1. Adjust the Voice Coil
The first thing you’ll want to do is check the voice coil. If it’s damaged, you’ll need to replace it. If it’s not damaged, you can try adjusting it. This is a delicate process, so be careful not to damage the voice coil. First, loosen the screws that hold the voice coil in place. Next, gently push on the voice coil until it’s in the correct position. Finally, tighten the screws back down. If the voice coil is severely damaged, you’ll need to replace it.
2. Adjust the Amplifier
If the amplifier is too powerful for the subwoofer, it can cause the subwoofer to blow. You’ll need to adjust the amplifier so that it’s not putting out too much power. First, find the knob or switch that controls the power output. Next, turn it down until the subwoofer receives the correct amount of power. If you’re unsure how much power the subwoofer can handle, consult the owner’s manual.

Then, remove the old capacitor and heat up the solder connection with a soldering iron. Once the solder is melted, remove the old capacitor and add a new one. Finally, reconnect the power and test the subwoofer to see if it is working properly.
6. Clean the Connections
If the subwoofer’s connections are dirty, it can cause the subwoofer to blow. You’ll need to clean the connections and make sure they’re free of dirt and debris. First, disconnect the subwoofer from the power source. Next, remove the screws that hold the speaker in place. Be careful not to lose the screws. Once the speaker is removed, you can access the connections. Use a cotton swab or a toothpick to clean the connections.
You can also use a can of compressed air to blow any dirt and debris out of the connections. Once the connections are clean, reattach the speaker and screw it back into place. Finally, reconnect the subwoofer to the power source and test it to see if it’s working correctly.
7. Check the Subwoofer’s Settings
If the subwoofer is still not working, you may need to check the subwoofer’s settings. First, make sure the volume is turned up. Next, check the crossover setting and make sure it’s set to the correct frequency. Finally, make sure the phase is set to 0 degrees. If all of these settings are correct and the subwoofer still isn’t working, you may try changing the setting to see if that fixes the problem.
8. Call a Professional
If you’ve tried all of these things and the subwoofer still isn’t working, you may need to call a professional. A professional can help you diagnose the problem and fix it. They may also be able to offer advice on how to prevent the problem from happening again in the future.
