hi, i bought a 2003 honda accord lx coupe in may and noticed that in the last 2-3 months there is some noise coming from the area on top of the cd player, around the dashboard, sort of a rattling noise. i'm having it looked at later next week, didn't really get time before, but is this a common problem? no idea where it came from, it rattles a lot lately, especially when the car is stopped at a light. also is there any way for me to find out if the warantee covers the speakers in my car, the rear right one seems to be humming a lot. Thanks.
