OK, maybe I never noticed it, before I got my components, but when there is no sound being played, it's like the tweeters are making this air flow sound, like it's when you get snow on the tv, the audio that comes along with it, but its really low on the tweeters, but i still can hear it since it's near my head. What could cause this, I'm thinking it's my amp, or the X overs, but I'm not too sure. I think the rear speakers do it to but ill check it out tommorrow. It's doesn't really do it, or it's drowned out when music is playing. I don't think its alternator noise because it does it with the car off to. What could be doing this? Btw, its the infinity 6000CS, on a sony 200 wrms 2 channel amp, but the amp is also running my rear speakers, so it's in 2 ohm load for both channels.
