I often hear a vibrating sound from the passenger door speaker. This only happens when I play the radio - I don't hear it with CDs. It sounds like a cracked/broken speaker. The dealer said it was the amplifier, which they replaced, but the problem continues. They did not bother to look at the speaker itself, they said they ran a diagnostic test.

Any thoughts? Could it just be poor radio reception? But why only on the passenger side?

I have noticed too that at a certain frequency (don't know how many hz exactly) the passenger speaker vibrates and it sounds awful. The dealer you went has no clue about physics. Vibration occurs when the frequency of the source that causes the vibration matches the frequency of the material of an item... in very simple terms. A simple fix for me was to remove the panel and speaker and add a bit of tape behind the edge of the speaker, therefore changing the frequency of the material of the speaker. Since I removed the panel I also fixed that annoying rattle on the window switch panel of the passenger door too, using some more tape under neath it.

BTW, a dealer who throws parts on a car hoping that will fix anything and then saying they did a diagnostic test... oh! please! haven't we all heard that bull before...
