As title says i just got the limited trim sonata, with dimension 7 speaker stereo, no nav. as I play music mostly hip hop I notice whether its on xm or cd quality, on certain bass levels i hear a rattle from my front side driver door top left corner before the window begins. I have my bass on set to + 3 keep on concert eq. the rattle isn't too annoying, if i put my window down a little it goes away for the most part. Am i just a little too nitpicky, or do others have the same rattle and have brought it in to be serviced. Or is it just the nature of the car and don't let it bother me.
