Ok, I know I found this post somewhere, but I couldn't find it so anyways I have a weird high pitched squeeling noise coming from somewhere, I think its in my engine. I hear it mostly when I'm in first gear. What is it and how can i fix it? I heard it had something to do with my alternator? Am I right? C'mon professional sound gurus, I need help!

Does the noise go up and down with the rpm of the engine? If it does you probably need a ground loop isolator for the RCAs and check your grounds.
