Cars are made of metal coverings, and these metals vibrate as the sound waves from the speaker turns into air molecules. Hence this energy transformation is the underlying cause of the rattling.

Rattling does not usually occur on surfaces that are acoustically dead, as these surfaces are not directly affected by any sound wave present. Therefore, areas like your car’s headliners, car body and dashboard cannot be affected by the sound waves, as they are acoustically dead.

How Do Speakers and Subs Work

A proper understanding of how your car speaker and subs work can help you detect the cause of those rattling sounds from your car audio systems. Both speakers and subs transform electrical waves into sound waves. By the back and forth movement of the cone, speakers and subs can move air at an accurate frequency.

Hence, when the cone gets damaged, they might not be able to provide the right sounds. Speakers are known to offer high-frequency sounds, and low range sounds are inaudible on speakers. These speakers have a voice coil with an attached magnet, a suspension, and a diaphragm.

Subs, unlike speakers, are created in a manner that they play deeper bass frequencies. The major components of your subwoofers include the Cone, Backplate, Voice coil, Spider, Voice gap, and Surround


Car speakers and subs provide an excellent driving experience, as tedious journeys can be made fun with good music. However, when this fun experience starts turning sour due to rattling sounds from the speakers and subs, it can be not very pleasant. Hence, it would be best if you looked for a way on how to stop rattling from car speakers and subs.

There are various causes of these rattling sounds, and you have to detect where these sounds are coming from, to provide a perfect solution.
