1995 grand prix
do you have a test light?your speaker wires should be four sets of matching color,dark/light blue,dark/light green,dark/light purple and one other matching set of colors. then there should be one black wire which should be ground.with a test light you can find your power and accesory wires. your power wire will always have power with key on or off,the acc wire will only have power when key on. i hope this will help.
