    Unhappy A lot of noise.......Please help

    I have this problem with noise. I have A LOT of noise coming out of my speakers and I can't figure out way. I have the sound coming out of the computer and into the AUX IN on my radio. The AUX IN is for things like MP3 players. I only have the noise problem when the computer is running, mainly when the HD is working. I thought it might have been the HD was to close to the MB so I moved it farther away from the MB and I still have the noise. I can't seem to figure out way. Any ideas?

    Try muting the Mic line, I have seen something close to this before. When you have the mic line un muted and nothing plugin into it, it will some times pick up interference.

    I made sure I had everthing muted, I was thinking that, that might have been the culprit. But not so. If the car is not running I get a hum and a thumpping, like a heart beat, coming from my subs. The only time this happens is when I have the AUX IN selected on my head unit. I tested the input using a MP3 player thinking that it might have been the head unit, but I didn't get any noise. Now when the car is running , that's when I get the wining and the hum AND the thumping. I'm going to stop on my way home from work today and pick up a ground isolator. I hope this will take care of it.

    Thanks for all your help!!!

    I went to Radio Shack and got a ground isolator and it took care of it all. It's so nice not having unwanted noise, Thanks guys!!!

    Radioshack only has the one kind and I think it was around $17.00. I would go ahead and get one, just to be safe.
