Modding a radio? Answered

Hey im trying to modify my cars radio to have an aux input using the CD players audio hookup to the main  IC. 

i cant find any datasheets on any of these ic's if i had them i would be just fine.  are the black wires that come from the CD player the audio signal wires? if they are could i easily just splice into that circuit?


Get the service manual for the radio, rather than look for chip numbers.


The audio amp IC is most likely attached to the heatsink.
If you can get the numbers from audio amp IC, then
you can probably find a datasheet with pin outs and trace
the best point to tap into.
