I have the rad/cd ( cd at bottom) with separate amp and have lost the perm and ignition power to the rad/cd but it is still available at the amp end. Tried tracing cable from rad/cd but can't work out where to goes and then parallelled with the amp supplies. Could anyone please enlighted me. Thanks

I am attempting to install this unit in my car , firstly does the unit come before or after the amplifier and secondly does anyone know the pin layout on the back of the radio. Many thanks
