I have seen a case where the oxidation of speaker
wire has been so bad that the speakers wouldn't
work. Cut back to clean wires and the speakers
would work....
Resistance issues a possible reason?
The fact that you cut it back, and it worked fine, supports my point. The oxidation is non conductive, it acts as an insulator. Remove the oxidation where you make the connection, and it won't matter if the wire is oxidized elsewhere.
