I think you're playing in a gas pond with matches here. I would suggest you take your car and system to a reputable radio installer and see what needs to be done.

A red flag to me is your door speakers. If these are the original speakers then you have a mis-match. If you bought all new speakers for your system then, are you sure the speakers match the freq and output of the radio's amp? Kenwood systems are great, if installed correctly.
