Hi James, Im AL the owner of Big As Auto Repair.

James, Cadillac stereo systems have an amplifier and usually when there is no sound from the speakers its because either the fuse to the amp is blown OR the amp itself is bad. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

If someone else put in an aftermarket radio, they probably used their own speaker wires, and disconnected the factory wires from the speakers.
