96 Sebring Factory Components

Hey guys... been a loooong time since I worked on a Chrysler Sebring.  I noticed that it has the factory compontents in it.  I know that the factory 6 1/2" speakers in the doors only play mid-bass.  The radio is the factory CD/Cassette with the Joystick to fade the speakers.  If anyone has done these before I am wanting to either just put components into the car using the factory cross-over points or maybe just put some coax speakers into the door and see if I can hardwire it.  In the past we used to just put a new radio into the car and then new speakers but this customer is a pain.  They want to keep the factory radio and just fix the door speakers.  Basically the tweeters are blown in the dash and the mid speaker is sounding really bad as well. 

I thought the speakers were 6x9's as well but after pulling the door panels off I found out that they are the oversized 6 1/2's
