Oh yeah, did you check to see if the problem existed with the engine off? It might be because of the alternator whine or something like that.
i thought it was my mp3, so i put in an original music cd and the result was the same at high volume. i don't know if the problem exist with the engine off, i will try it out later. if you have the same problem as me, it might be because of infinity speakers, if u already had ground wire to the nagetive on the battery and wired the tweets correctly.
