I don't have a TSX so I can't tell you which color is which. Assuming you are wanting to know the polarity, and you plan to cut and splice........ Cut the wires. The take a aa battery and put one wire to the - on the battery and - on the speaker terminal. now take another wire and touch it to the + terminal on both the speaker and battery. If the drivers cone moves forward, the polarity is correct. If the drivers cone pulls inward, the polarity is oposite.
Hope that makes sense.
