I bought my daughter a V-6 Stang a few months ago & now the stereo is going out. It has the bone stock radio/casette/CD player in it. I want to replace the head unit & speakers. She listens to rock, country & jazz. What would be a good system for her with a budget of 500 to 750 bucks? I will probably have an audio place do the install being I'm getting to old to be getting up & down and in some awkward positions. Any suggestions will be appreciated. Thanks.
