Then you will need a converter to convert the single ended signal from the CD changer to the balanced signal expected by the amplifier. > My Saab already comes prewired for power in the trunk.

The control signals for the CD changer travels over the communication bus (I-BUS, a CAN-bus) used by a lot of electronics in the vehicle. Do not connect anything to these wires unless you fancy a car that won't start. The audio cables from the CD changer to the head unit is not shielded, they are a twisted pair intended for balanced audio signals. In this case, a wire is not just a wire.
