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

**Bullwinkle777** · 05-04-2008, 12:46 PM

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?

you might wanna check out some thing called "ground isolator" or something in the faq section from the car audio forum"

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!!!

do you have a powercable running close to the audio cable?

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!!!

cool.. hey u think that's gonna solve my problem too? I haven't installed my umpc on my car, but when i do, i plan to run it off the cigar jack... I will most likely have some noise problem or maybe not.. if i do, i am thinking about getting one as well.... which model did you get and for how much?
