hi, I had connected Gale XL189 speaker cable (bare wire), into the micro speakers (push/grip connecters) of my home theater kit. No probs with the sound, although I noticed when I took the bare wire bit that goes into the speaker, it was badly stained and tarnished (oxidised)?. Has anyone "tinned" these ends that go into the speakers. Does it help? Any advice would be appreciated. Cheers.
