2001 Chrysler Town and Country

piece of cake to make this work without factory radio. the data bus from the radio turns the amp on, now the thing it is the amp turn on goes to a relay on the firewall then to the factory amp, on the output side of the relay is a 12 volt signal, so all you have to do is wire the amp turn on from the new H/U to the output side of the relay. To find out what relay it is, unplug the factory radio then plug it in and listen to which relay clicks on and off. Piece of cake
