I don't know why you want to bi-wire, but, go ahead and try it. I'll try to answer your question.
First, is your center channel speaker set up for bi-wiring? It must have 2 sets of input terminals that are currently connected by a jumper. This means that you must have two positive input terminals and two negatives.
First, remove the jumper between the 2 positive terminals and the one between the two negative terminals on your center channel speaker.
You'll need 4 lengths of speaker wire. (If you have bi-wire cables, then this is not applicable.) Take 2 of the the wires and connect them to the positive terminal for the center channel on your receiver. (You can twist the bare wire together, clamp them together with a spade, or combine them into one bananna plug.)
Take one of the positive wires and connect it to one of the positive input terminals on your speaker. Take the second positive wire and connect it to the second positive input terminal on your speaker.
Do the same thing for the negative connections.
Let us know how it sounds.

If you need, I have a small bitmap sketch showing this. Send me an email and I can send it to you.
