normally the only way to tell would be to check the speaker connection. The speakers are usually marked with a red dot or a "+" sign .. check both speakers to see what coloring has been used. A lot of foreign made stuff is done very cheaply disregarding standardisation or normal conventions

Or just chose one and try it. Its not going to hurt anything and with headphones especially it will either sound correct or will sound really weird.

I would think the red/green wire is the positive. Thank God we're not talking about disarming a bomb! Red wire or blue wire. The guy always cuts the blue wire and the timer goes into warp speed. That's Hollywood for you. If it were me building that thing I'd make it so as soon as you cut the wrong wire, you cash in on your life insurance

I forgot the most easy solution of all .. if you already cut the wire use an ohm meter to measure the resistance .. the -ve lead will show equal resistance to both positive leads.
Measure back from the plug .. also the plug will have the closest contact to the cable as the negative with the tip & centre being the +ve wires to the left & right speakers
