How do you bi-wire?

I've tried bi-wiring by connecting the two ends of speaker wire together on the end that connects to the amp. Then, I separated them at the speaker. There was improvement. Then I separated the wires that connect to the amp and connected them separately to speaker "A" and "B" connections. I turned both speaker switches on. Connecting separately to "A" and "B" improved the clarity quite a bit. My question is, am I doing this right. I know it must be a simple question, but I don't know.
