Some Effective Ways How to Fix a Blown Subwoofer Coil
1. Rewire the Coil
The first thing you should do if your subwoofer coil has blown is to check the wiring. If the coil is not wired correctly, it can cause a short circuit. This can lead to the coil overheating and eventually failing. To fix this, you will need to rewire the coil. First, disconnect the power to your subwoofer. Next, remove the woofer from the enclosure. Once the woofer is removed, you will be able to access the coil.
Carefully examine the coil and the wiring. If you see any damaged or frayed wires, you will need to replace them. Once you have replaced the damaged wires, you can reassemble the subwoofer and reconnect the power. Finally, try playing some music to see if the subwoofer is working properly.
2. Replace the Fuse
If your subwoofer has blown a fuse, this can cause the coil to fail. To fix this, you will need to replace the fuse. First, disconnect the power to your subwoofer. Next, locate the fuse. It is usually located near the power cord. Once you have found the fuse, remove it and replace it with a new one. Finally, try playing some music to see if the subwoofer is working properly. It is important to note that if your subwoofer has blown more than one fuse, this is a sign of a more serious problem. In this case, you should take your subwoofer to a professional for repairs.
3. Use a Power Conditioner
If your subwoofer is constantly blowing fuses, you may need to use a power conditioner. A power conditioner is a device that helps to regulate the voltage coming into your subwoofer. This can help to prevent power surges from damaging your subwoofer. Additionally, a power conditioner can help to protect your subwoofer from damage caused by power surges.
4. Check the impedance
The impedance of a subwoofer coil is important because it determines how much power the coil can handle. If the impedance is too low, the coil can overheat and eventually fail. To fix this, you will need to check the coil’s impedance. First, disconnect the power to the subwoofer. Then, using a multimeter, measure the resistance of the coil. The resistance should be between 4 and 8 ohms. If it is lower than 4 ohms, the coil is damaged and needs to be replaced.
5. Try a Different Amplifier
If your subwoofer is blowing fuses, you may need to try a different amplifier. An amplifier that is too powerful can damage your subwoofer. To fix this, you will need to find an amplifier that is specifically designed for subwoofers. Additionally, you will need to make sure that the amplifier is not too powerful for your subwoofer. If you are not sure how to do this, you should take your subwoofer to a professional for help.
6. Use a Higher Quality Wire
If you are using lower-quality wire to connect your subwoofer to the amplifier, this can cause the coil to fail. The wire may not be able to handle the current flowing through it and will eventually overheat and melt. Use a higher quality wire such as OFC (oxygen-free copper) to ensure that this does not happen. Avoid using speaker wire as it is not designed to handle the high currents flowing through a subwoofer coil.
7. Increase the Airflow
Overheating is one of the most common reasons why a subwoofer coil can fail. To prevent this, you will need to make sure that there is adequate airflow around the coil. If the coil is enclosed in a box, make sure that there are ventilation holes to allow air to flow through. Additionally, you can try using a fan to help cool the coil. If you live in a humid climate, you may also want to consider using a dehumidifier to help keep the air around the coil dry.
8. Call a Professional
If you have tried all of the above tips and your subwoofer is still not working properly, you may need to call a professional. A professional can help to diagnose the problem and determine the best course of action. Additionally, a professional can help to install a new subwoofer if necessary.
