I can hear alternator noise coming through my radio (stock head unit). 94 gt. How do I resolve? thx

Probably need a new altenator, I think they make some sort of noise filter for that prob

Ive herd that if you have a bad spark plug wire it can cause radio interference, dont quote me on this though.

check your grounds...i know its easier said than done. have you tampered with the radio or added speakers. you describing what sounds like to me as a bad ground....

have you changed spark plugs recently? you need to make sure that any spark plugs you get have a resistor in them other wise you will get that noise though the speakers
