Weird Static Noise

[Cobra1237]

I bought a 2001 Volkswagen Golf towards the end of February. About two weeks ago i decided to install a new headunit and speakers to replace the stock units. I decided to buy a Panasonic CQ-C7301U. I started to drive around and i noticed that at certain speeds there is a static noise comming from the speakers. It did this on all FM stations, AM stations sound how they should. CDs/MP3s play fine and i dont hear any noises with those, so the speakers are fine. About two days later i take it back to circuit city to have them look at it, the guy spends maybe a half hour on it and says he replaced the antenna adapter. Ok, so i take the car out again and i find the noise is still there. I take it immediately back to them and thats when they threw their hands up and said its engine noise, therefore not their problem. Taking one of their installer's advice, i decide to replace the panasonic with a pioneer, he claimed pioneer's have better tuners on them. So i replace the panasonic with a pioneer DEH-P6700MP. I drive away and it has the exact same problem. I decide to try and talk to other car audio places to see if they might know what the problem is. Everyone i talked to thought it could be the antenna. So i bought an aftermarket amplified antenna and hook it up to the pioneer. Same problem. I put the radio back how it was and tell the guys that didnt fix it. Now they dont know what it could be and said they would disconnect all the speakers and hook them up one by one to see if they can find the problem. I knew right away that wouldnt fix it because i think its not a speaker problem. Now today i go back to circuit city and return the pioneer because i am not going to pay $230 for a radio that does not work right. They install my stock radio back in, but now the stock radio has the exact same problem as the other ones. It did not do this when i got the car and i never heard static until circuit city touched my car. I am afraid that if i talk to them they will not hear the problem because the car must be moving to hear any static, and at idle there is no static. I am wondering what they could have done to cause this. The static doesnt seem to matter what RPMs im at. Ive heard it at all sorts of speeds, except when the car is stopped the static stops. It never did this until i had a new radio installed and im at a loss on what could be the matter. All i changed was the head unit and speakers. I have no external amps that would receive interference. Any ideas or help is appreciated.

your car doesnt happen to come with an integrated amplifier anywhere does it? That could very well cause the static. Also the actual antenna lead from the antenna to the deck could be bad. try attaching a new antenna DIRECTLY to the HU. see what happens.

If its still there.. take a copper pipe or tube and jam it half way into the ground. Wrap a wire around the tube and then tie the other end of the wire to a clean bare metal spot on the cars frame. Leave it that way for the night.

This sounds exactly like a problem I had where the car had static electricity running through the frame. the only way to get rid of it is to ground the car, and drain the electricity.

Im not sure, is there any way to tell?? The radio was just a stock AM/FM/Cassete player. Not sure what kind it doesnt say anywhere on the unit.

probably no amp then. Try those ideas and see what happens.
