I have read the other post on noises. I feel I have done it all. Anyones help would be appreciated. Here it goes!
I have a 6 channel amp, three sets of RCAs from my Blaupunkt running down one side of the car. Down the other 4 gauge power, amp turn on cable, and less than 2ft of 4 gauge ground. I made sure that the amp has no contact to metal. Both power and ground are clean. Disconnected RCAs, no amp noise, so I feel it isn't power or grounding of the amp. Connect one set, noise, switch back and forth, noise still there. Used a common ground for the radio with the amp, noise. Changed ground points still noise. I don't know and I am blowing a fuse (personally). Help

If you have access to some other equip for testing, I would try a different head unit first, and then try a different amp. It is possible you have a faulty component

If you have a portable "boom box" radio which has a auxilary input hook up 1 set of the outputs from the Blaupunkt and get a set of headphones and plug them into the boom box. Listen for the whine. The boom box, being 110v AC, is electrically isolated from the car and WILL have no noise. Any noise heard will be directly from the Blaupunkt. Now you can try regrounding the radio. Also try connecting and extra set of RCA cords from the Blaupunkt to the boom box. Be sure the RCA's are outside the car. This will show if the RCA's are picking up the noise. You may have to move the RCA's to eliminate the noise. HTH Ed

Thanks Nathan and TurboTaMan. I got to screwing aroung with the RCAs and unplug all of them. When I reconnected them I did it in this order.

It doesnt make any sense, but it works. The only thing that worries me is that it is not suppose to be that way. As far as the noise is concern it is gone. Any other advice as why it works this way?
