I'm looking for a wiring diagram and amp specs for the 2000 (and earlier) Chrysler Cirrus with the Infinity amp and cassette radio with CD control and a joystick fader.

All my speakers are/were blow. I just put in new 2 ohm Infinity 2-way 6x9s in the back but I'd like to know more about the amp before buying new fronts.
Any chance ???...Please...

 

I thought the amp had all the cross-overs but now I'm thinking there must be some cross-overs in the radio too. I've got full sound from the cd player (6 disc in the trunk) but no bass from one (rear) coming through when listening to the radio.
I'd really love to put in a new indash head unit with a cd player and mp3/aux input but everything I read/hear says there is no such head unit compatible with the amp. Any suggestions? I did find a used factory original radio headunit on eBay for about $50 shipped.
