I don't know the electrical in mitsubishi cars that well but it does sound like a fuse. Did you look under the hood? There is always a fuse box there. If it's not a fuse then a find wiring diagram for the vehicle online or talk to a dealership about them printing you out one. Then get a multimeter or test light and trace from the stereo back.
