Intermittent sound issue
So I have a 2013 c300. I have noticed that on occasion, the driver side speaker seems to act funny. It is kind of hard to pinpoint but I have noticed that the sound "seems fuller" after a bit. Like I am listening and all of a sudden the left side "comes in better" and kind of fill in with base and volumn. You almost would not even notice a problem but you certainly notice when it fixes itself (sounds better and fuller).
Its under warrenty but I know that it is going to be really hard to show the dealer or re-produce it. "Hey, sit and listen to music for 10 minutes and see if you notice it come in better on the left after a bit..."
Any ideas as to what I could check/test? Or has anyone else had/seen this? It's subtle but I am curious...
Thanks!
