I had a similar one but it was on the driver side. However, after a while later that sound just disappeared and fixed it by itself.. Now, the speaker grill on the passenger side is giving me some random clicking sounds only when going through bumps..
Here are my 2 cents and this learned from a hard lesson. If your front speakers are NOT broken, DO NOT replace them. The original speaker fit SO tight with the housing, and when you replace them with after-market speakers, it might give you some random clicking sounds in the future.. That's just my observation. I'm amazed by how precise German engineering was 20 years ago...
