you put in the radio like normal then you have to go into the trunk and to the left behind the carpet there is an infinity amp you would use a phase tester and find all your speaker wires and bypass the amp from input harness to output harness thats the best way but you can also just hook up the blue amp turn on wires when your installing the radio although doing it this way the speakers might sound distorted at higher listening levels hope that helps you have a good day.
