i have a 2004 GT with the mach 460 sound sytem. when i just turn the key to accessories, i hear this loud kind of staticy sound and sometimes its really loud different kind of sound. when i crank the car my exhaust kind of drowns it out. this is really noticeable when the volume is down but if you turn it up just a little bit at a time its still there but drowns it out unless you really try to listen for it. it annoys the piss out of me and i want to take it back under warranty if i can. i asked the ford dealership about it before and they said that all of them do it but thats b.s because my brothers got an 02 with the mach and it doesnt do it. i just want your facts and opinions please...
