ive still got a prob with my cd changer if anyone can help? ive got a kenwood mask up front,and 10 cd changer in boot, every so often the cd changer will just crash like a pc

the music will start to crackle then pack up and the cd changer wont do anything,you can still change tracks or cd via the head unit but the changer wont respond,after around 45 secs-5 mins it will be ok again

i noticed yesterday that if im driving steadily then its ok,but as soon as i put my foot down it starts again! if i back off the throttle its ok again after a minute or so

whats going on? as im getting really pissed off with it now
