I have a RCA audio cable for my ipod. I plugged it in to the back of my Kenwood stereo deck and the volume dosent work. The volume is being controlled by the ipod not the stereo so it is very quiet. No matter how loud I turn up the stereo it dosent turn the sound up. Also the ipod sound plays no matter what mode, radio aux or cd, that I'm in. Any ideas on what's wrong?
