When adjusting the AM antenna trimmer in cars with a rear speaker, you need to unplug the fader rheostat to gain access to the trimmer screw, and the Chassis Service Manual instructs you to use a wire to shunt the terminals of the socket that the rheostat plugs into so that when you turn on the radio to adjust it, you don't blow the output transistor.
