The Speaker wire to use as the negative really doesnt matter when installing new wire as long as all speakers are hooked up the same way. Normally though most people use the solid colored wire as the negative.
One way to know is to hook them up and if you see if the speaker cone moves inward on a bass note. If so, you have the + & - reversed. If the positive and negative is not marked on the speaker, connect a 9 volt battery quickly to the speaker. The cone will move outward when you have the + & - connected correctly. It will be either gray, or gray with a white or black tracer.
