which Ic using for power amplifier?

there is a luck test ... if the ic is not blown but not powering on , then take a relay (12v) connect one side of relay coil to deck grount , and next coil just touch and release to vcc pin of amplifier ic , the relay makes a 'tick' sound , as it produce some back emf there is a possibility of switching it on , in my case it works .. I has the same prob with my chevorlet inbuilt radio...
