Speaker popping sounds on right side
So my new '13 Titanium I got in August has this issue with the passenger side speaker making popping/cracking noises. It just started today and they seem to start around 10-15 minutes after driving and it doesn't matter what I am listening to (FM or Sirius). I only have 2500 miles on this car and I am a little worried. I plan to ask about it at either my inspection or 5k checkup but anyone else have this issue?
The only thing that changed is that it is getting colder out (~30 degrees F) but that's about it. I wouldn't think that would affect that though. I also do not listen to radio excessively loud.
