These are speaker output wires from a little amp board. Can anyone identify what the polarity is?

Thanks.​
 
I'd hazard a guess at + on the left, as most cables have a line up the positive & ground is darker. The 2 left feeds have less print on them. Are they connected to anything expensive o_O
 
The single white is off putting :confused: or is it the one with the X.
Is there no print on the board connections. 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. The positive isn't because of the switch so, deduct from that.

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.

Worth a shot. Just tried that, basically hoping to at least find a common ground.

Oh well thanks for the suggestions. This is it BTW.

The reviews on it are all quite positive. It will be replacing this assembly from a ~25 year old Altec Lansing 2.1 computer speaker system.

So I'll be going from a ~3 lb assembly to a 102 gram (22 gram + 80 gram old DLink PS) one.
