I vote for wire bound noise coming through the amplifier.
Check that the battery is in good shape and the terminals are clean and tight. I have seen this before, not on Saabs and a choke fixed it. Needed to put on the radio constant feed, not the main power supply cable.
None of the speaker wires should be grounded.
A bad alternator will have a nasty output wave form that creates problems. You can also try putting a temporary cap across the battery terminals to see what effect that has. If that works, the battery is not able to sink AC waveforms from the alternator.
