Are you referring to the color at the end of the cable,right next to the actual spade?? All the speaker wires I've ever seen are black and red,(one each)at that end of the wire.Red is always for the + connection to the speaker,which should be marked as such. Your amp should also have a + post,where the red goes at the other end. So it's red to red,for each amp end and that red goes to each speaker + terminal...Further I'm assuming you have one spade each for the AMP end and 2spades each for the speaker end.---For some wires they might designate a certian spade for the low end. (usually a thicker wire)As you trace the spades from the red+ from the amp---each of these should go to the + on the speaker--top and bottom posts. The black goes the same way to the - posts,top and bottom.
