Waddle noise from the bass of the stereo near passenger side.

[JiNuWiNe]

One day, out of no where, I started to hear this waddle noise created by the shock wave of the bass somewhere near the passenger side. I can't seem to find out what the problem is, I've looked for it but found nothing. It's not loose change or anything. Does anyone have a similar issue?

Thanks.

It's colder these days and our cars are making a lot more ticking and weird noises. I think I have the same problem but when I pulled on the driver's seat belt, it stopped.

same shit here, its just random.. comes and goes. could be a piece of adhesive that unsticks due to weather and sticks again. Im not sure just a wild guess

If my car is still covered under warranty, should I bring it to the dealer for such problem?
