Mirage M3si owners question?

Can someone who owns a pair of Mirage M3si speakers confirm the color of the positive and negative wires that come out of the bottom of the speaker? There are four wires that come out of the bottom of each speaker and attach to the binding posts. Are the solid black wires the negative wires and the green and yellow wires the positive ones? I called Mirage and they never got back to me. Thanks.
As I look at the wires with the speaker laying down onto its front...the posts from left to right are Black, Red, Back, Red. The wires are Black, Yellow, Black, Green. This is the same for both the left and right speakers.
Thanks Sgs. That's what I needed to know.
