What causes bad reception? Sometimes it gets better but most of the time I can barely get any stations. This is happening with my radio in my old vette that is made by ACS or whoever that company is that makes the custom radios for old vette dashes. Could it be something wrong in the tuner or would it definetly be my antenna. I wouldn't think much could go wrong with an antenna. I also have an amp on this unit which I think is on its way out. I guess I should just pull them both and drop tham off at an electronic store and hope they can be fixed.
