I recently ordered a 60GB unit on 1/4/02, can't wait to get it!My question is I currently have a Kenwood Z919 car stereo(the one that playes data Cds). This was cool until I heard about empeg. I am wondering if can keep this Kenwood unit (to have a radio feature) and just install my empeg below it. I read for empeg you need a seperate amplifier. What does this mean? I am not too technical when it comes to car stereos. Can my empeg be installed in my car in its current condition?
