Pop or Clunk Sound
 

Not sure what might it be, but yesterday went messing with the Aux port via IPOD, there was a large clunk or pop sound coming from driver side door after the car's been sitting for 8 hrs. This morning, the same clunk happened but while messing the radio and started the car for about 5 minutes. It didn't sound like it was coming from the speaker and the speaker works just fine. Anyone ever experience this?
