LOL. Maybe the markings are some sort of Chinese morse code. Well seeing as the connectors are keyed (there is a 3rd sub output too) I'll just pick by position and use the 'X' and 'white' as ground to the speakers. I should end up with relative phase (which is fine), as opposed to absolute.The single white is off puttingor is it the one with the X.
Worth a shot. Just tried that, basically hoping to at least find a common ground.Assuming it has an on off switch, could you not do a continuity test on the switch. Ground should give constant ping as its open through.
