Check the round multiple connector doors to door post. The connections are very likely corroded and green. They carry all the door electrics including speakers. Use your favourite method for cleaning them as I have no preferred solution. The speaker voltages are very prone to this area.
Best is to check the speakers using a AA cell, if this is OK then the power to the preamp and the power amplifier. You might need to have a signal test using a audio signal injection to confirm the case of the faulty audio stage.
