A blown subwoofer coil can be a frustrating problem, especially for those who enjoy loud music. A blown subwoofer coil can result in a lack of sound, distorted sound, or even physical damage to the subwoofer cone.
In this article, we’ll discuss what causes a blown subwoofer coil and how to fix a blown subwoofer coil. This guide will help you to get your subwoofer back in working order.
Symptoms of a Blown Subwoofer Coil:
One of the most common symptoms of a blown subwoofer coil is a lack of sound or low volume. This can be caused by a break in the voice coil, which is the part of the subwoofer that produces the sound.
Another common symptom is distorted sound, which can result from a misaligned voice coil or a loose connection within the subwoofer. Rumbling or crackling noises, as well as physical damage to the subwoofer cone, can also indicate a blown subwoofer coil.
What Causes a Blown Subwoofer Coil:
There are several factors that can contribute to a blown subwoofer coil. Overloading the subwoofer, either by playing music too loudly or by using the wrong type of subwoofer for the application, can cause the voice coil to overheat and eventually fail.
Poor quality subwoofers are also more likely to blow out due to manufacturing defects or subpar materials. Exposure to extreme temperatures, such as leaving a subwoofer in a hot car, can also lead to a blown subwoofer coil.
Finally, age and wear and tear can cause the subwoofer to deteriorate over time, leading to a blown coil.
How To Fix A Blown Subwoofer Coil?
Tools and Materials Needed:
To fix a blown subwoofer coil, you’ll need a few basic tools and materials. These include
- Screwdrivers
- Wire cutters
- Speaker repair glue
- A replacement subwoofer voice coil, and

Make sure that you have all of these items on hand before you begin the repair process.
Step-by-Step Guide to Fix a Blown Subwoofer Coil:
Remove the subwoofer from the system:
Before you begin the repair process, you’ll need to remove the subwoofer from the system. This typically involves removing the screws that secure the subwoofer in place and disconnecting any wires that are attached to it.
Disassemble the subwoofer:
Once you have removed the subwoofer from the system, you’ll need to disassemble it to access the voice coil. This may involve removing the subwoofer cone and the surrounding gasket, as well as any screws or clips that hold the subwoofer in place.
Locate the damaged coil:
The next step is to locate the damaged coil. This is typically located near the center of the subwoofer, and you should be able to see if it is damaged by looking for any breaks or frays in the wire.
Remove the damaged coil:
Once you’ve located the damaged coil, you’ll need to remove it. This typically involves carefully cutting the wires that connect the coil to the rest of the subwoofer and then carefully removing the coil from the subwoofer frame.
Replace the damaged coil:
With the damaged coil removed, you can now install the replacement coil. This typically involves carefully attaching the new coil to the subwoofer frame and connecting the wires to the appropriate terminals.
Make sure to use speaker repair glue to secure the coil in place.
Reassemble the subwoofer:
With the replacement coil installed, you can now reassemble the subwoofer. This typically involves reattaching the subwoofer cone and gasket, as well as any screws or clips that hold the subwoofer in place.
Test the subwoofer:
Finally, you can test the subwoofer to make sure it is working properly. Connect it back to the system and play some music to see if it produces sound.
If it does, then your repair was successful. If it doesn’t, then you may need to repeat the repair process or seek professional help.
