Im installing a aftermarket cd player. Is there a factory amp hidden someplace. I wired it up and get nothing. Im thinking Im going to have to run new wires to get the job done. Am I right on this one or can I bypass if there is a amp located somewhere I havent look. It is a 97 that had the factory cd changer with tape player. Travis

 

the amp is located in front of the spare tire.

 

No amp there just the shock sensor for the alarm. I know it has to be something beacause the wires are different at the speaker connection and at the radio connection it is the stardard GM color code. Anymore ideas. Traivs

 

Found it.
