I own a 1985 Mustang with the digital tuner radio, the one you can just yank out of the dash at a moment's notice. I notice that when I put a cassette in, it will play VERY quietly, ill turn it up all the way, and ill barely hear it. the problem seems to get better if the car is left out in the heat. for example, I will go to school and leave it parked in the sun, once I get back and put a cassette in, it will play louder, not as loud as it is supposed to, but loud enough for me to turn it...
