High pitched whine using stock head unit / aux input?

you may notice a difference........

is the wine going with the engines rpm, if you push on the throttle a little more does the pitch of the wine increase? this is usually because of a bad ground or thats been my experience with many cars. But you say you have stock equipment so that confuses me.....

if you were already planning on changing out the head unit, id say go for it...........but if its something you didnt plan on doing until you found this problem id say take it in to the dealership........

Yeah, the whine does increase when I speed up. My equipment is all stock.
