I am not sure of the model number, but it is a basic no frills CD player that was bought new a little less than a year ago from crutchfield for aprox 180 dollars. The problem....the audio output constantly changes from low to high. I cant stand it. It does this for everything, CDs and radio. Just recently the starter was replaced and that is the only thing that has changed with the car. I dont know if that could be anything. no electrical was touched besides disconnecting the battery. fyi- This is not on a Contique. All help is gladly appreciated, even warrenty, return info if thats what it will come to.
