Improper wiring can also lead to a blown subwoofer. If the wiring is incorrect or there are loose connections, it can result in power surges or the subwoofer not receiving the necessary power, causing it to blow.
Lastly, using an underpowered amplifier can cause a blown subwoofer. When the amplifier doesn’t provide enough power to the subwoofer, it can lead to clipping and distortion, ultimately damaging the subwoofer.
Understanding these causes will help you take necessary precautions, such as using a suitable amplifier, avoiding excessive volume levels, and ensuring proper wiring, to prevent blowing your subwoofer.
Testing Techniques To Determine If Your Subwoofer Is Blown
When your subwoofer stops producing the powerful bass and low-frequency sounds it once did, it may be a sign that it is blown. However, before jumping to conclusions and spending money on replacements, it is essential to test your subwoofer to confirm the issue.
One simple testing technique involves using a multimeter to check the subwoofer’s impedance. Set the multimeter to the ohms setting and connect the probes to the subwoofer’s positive and negative terminals. If the reading shows infinite resistance (open circuit), it indicates a blown subwoofer.
Another method involves disconnecting the subwoofer from the audio system and using a separate power source, such as a 9V battery, to test whether the subwoofer produces any sound. Gently touch the positive and negative terminals of the subwoofer with the battery’s positive and negative wires. If the subwoofer moves slightly or produces a clicking sound, it may not be blown.
Other testing techniques include visually inspecting the subwoofer for physical damages, checking for loose connections, and listening closely for distorted or rattling sounds.
By using these testing techniques, you can accurately determine whether your subwoofer is blown and then proceed with the appropriate solutions discussed in the article.
