Give a Listen

The easiest way to note speaker damage is by sound. If the sound quality of your audio system isn’t as good as it once was, you may have a blown speaker or a partially blown speaker.

Car speakers can sustain varying degrees of damage. A speaker that is blown out completely will issue no sound when the volume is at low to normal levels. At high volumes, you may hear a buzzing sound.

To isolate which speaker or speakers are damaged, adjust the balance on your audio system to the front, back, right, and left, listening to each speaker in turn. This will help you narrow down which speaker has been damaged.

Feel Your Way

You can also detect damage by turning up the volume on your car’s sound system and feeling for vibration from a subwoofer. While touching each speaker, turn up the base and see if the thumping or vibration feels off.


Handy motorists can also use an electric meter to tell if a speaker is blown. Set the the meter to read OHMS (impedance). Ensure that the speaker you’re testing is off, then put one meter lead on each of the two terminals. For a speaker that is blown, the meter will read infinite impedance. For an undamaged speaker, the meter will read 1.0.
