Best way to wire Speakers from mc501 amps

I'm new to this hobby, I just bought a ca2300 pre and 2 mc501 amps. I cannot up grade my speakers for about a year and currently have linn 5140 speakers.

I do not understand how to wire them, which post do I connect them to on the amps and should I bi wire and if so how should I do it and what speaker wire should I get?. Thanks in advance for any help
