Check to make sure that the speaker cones haven’t come loose from their mounting brackets. If they have, this will cause rattling when the bass hits. You can also try tightening the bolts on the speakers themselves. This will help them stay in place during high volumes.
If none of these options work for you, consider replacing your speakers with new ones they may be out of date or damaged in some way that makes them more susceptible to rattling than others.
What is bass, and why does it cause rattling?
Bass is the low-frequency component of a sound wave, and it causes rattling in your car speakers when you play music with bass. Bass sounds are created by vibrations in the air, which are transmitted by the speaker cones to the car’s body.
If you’ve ever heard someone say that their car is rattling, it means that something inside the car is vibrating from the bass usually, it’s the floorboards or roof. This vibration can be felt through your feet, but also through your seat or steering wheel as well.
It can be annoying if you’re trying to listen to music while driving, but it’s also potentially dangerous if your speakers are rattling too much in a crash, they may not be able to transmit sound effectively enough to let you know what’s going on around you.
It’s all about this thump. When there’s too much bass coming from your speakers and not enough air, it causes a lot of vibration in your car’s body panels—the metal parts that make up the exterior of your vehicle.
That vibration can cause rattling noises, which aren’t pleasant for passengers or drivers alike.
The steps to fix rattling speakers
If your speaker is rattling because it’s loose, you might be able to tighten the screws that hold it in place. If that doesn’t work, you may have to replace the speaker entirely.
If your speakers are rattling because they’re too close together, try moving them apart a little bit. If they’re still rattling, then either move them further apart or replace one or both of them with new speakers.
If your speakers are rattling because they’re vibrating against something else in your car, turn off your car and open up the top so that you can see inside it. Look for anything that might be touching your speaker and then try pushing it away from your speaker slightly.
You may also need to add padding between these two pieces in order to eliminate any noise coming from their contact with each other.
Why do car speakers rattle with bass?
The first thing to check is your car’s amplifier. If you’re using an external amp and it’s connected directly to your subwoofer, then you might need to change the settings on the amp so that it doesn’t overdrive the subwoofer or distort its sound.
How does resonance affect the sound?
Sound waves are what make up sound and they travel through the air like ocean waves travel through water. When you hear someone talk or listen to music, sound waves hit your eardrums and vibrate them at different frequencies.
Your brain interprets those vibrations as sound. It all comes down to something called standing waves. A standing wave occurs when two waves meet each other at their peaks or troughs.
As these two waves bounce back and forth off each other, they create interference patterns that repeat themselves over and over again. So if you put an object like a car speaker in between two speakers emitting these interference patterns, you’ll see that those patterns cause those vibrations to change depending on where they are in relation to the speaker and its frequency.
How to reduce rattling?
Make sure that the speaker is properly installed in its box. Check that there aren’t any loose wires or connections causing any problems, and make sure all screws are tightened securely.
Try moving the position of the speaker by placing it on a different surface in the box or removing it entirely for a while to see if there’s a difference in rattling when you put it back into its original location.
Try replacing the speaker with another one from your collection; this may solve any issues with rattling and improve sound quality overall.
Conclusion
It appears that the rattle is caused by the bass and it is not a matter of your car’s speakers. It seems that the bass comes from the amplifier, but not all amplifiers are alike. Some amplifiers will have more bass than others, so you’ll want to test out an amplifier before buying it to make sure it doesn’t rattle.
