Re: Stereo Vibration problem
I had that problem, usually it's one of a couple of things.
most probably the reason, it's the harmonics. you probably have something on or near it.
I had a pair of jacks touching the rear speakers, and i was wondering what that ringing noise was. at first i thought my bass was a little messed up, but it was the speakers vibrating against the jacks.
it could be the wire used to hook up your ipod/mp3 player I know for a fact that's the problem with mine. I just have to rotate the wire untill it works. Try playing form an ipod/mp3, and then from FM radio. check to see if there is a difference.
It could also be the song quality. needless to say a crappy quality song will sound very bad. one time, i thought i blew out my speakers, but the song i downloaded was really crappy quality.
I hope this helps!
