My Gf has a 2004 v6 vert and the speakers make a static noise. When you rev it up the noise goes up too. She took it to the local Ford dealership and they said it was fine...Yea right it sounds like crap. It used to only do it sometimes but now everytime. Even if the radio is off, still static noise. Any ideas? Thanks

Check for bad/cracked plug wires. Also there should be a small round can (capacitor) on both the alternator and the coil with single wires coming out and bolted to ground. Any of the above problems can lead to ground interference.
