Hey Silver I got a good one for you? With the radio on only AM/FM and the rear defrost on there is a painful screaming noise out of my speakers. Any ideas on how to figure out whats goin on and where?

 

Sounds like crossed wires. Do you have an aftermarket radio and/or amp?

 

u know i have the same problem but i dont think my wires are crossed i think it may be a bad ground i have aftermarket speakers and amp where is a good location for my ground to not get that noise that comes out of the speakers

 

Yup, it could also be a bad ground. I wasn't sure if he had aftermarket items though.
The place I used for a ground was the seat belt bolt...actually, anywhere, lol. The best thing you can do to make sure any ground is good is to sand off the paint and use a conductive screw or bolt and not the black screws. Also use the correct gauge ground wire.

 

thats where i have the ground in the seatbelt bolt did u get another bolt or the stock bot i think the wire might be bad tho its a nice gauge wire too i forget what tho but its pretty big

 

Does it do it with the engine off? My fogs are transfering alternator noise to my stereo somehow, guess I need to check the ground on them.
