Does Bi-amping double the power?

Hi guys,

I have a Marantz PM6005 (35w/ch) in the bedroom and I'm wondering if using the A and B speakers terminals to one set of speakers would increase the peak power to 70w/ch?

In the same vein - If hooked up to 2 sets of speaker, do both sets get 35w/ch or does that get split in half?

Thanks!
