Not S12 Related Sorry

ok my wife has a galant and the dash lights dont work. she says that when she brought it hone it did. she put a radio in an 2 speaker wires i think sparked. the fuse is ok and sometimes the dome light controls the radio on off does anyone know mitsubishi and can you help

Turning the dome light on and off controls the radio? Sounds like she has the radio power connected to the wrong thing. Only thing I can tell you is pull the radio out and check each wire. And checking all the other fuses can't hurt.
