Bi-Amping, best way??

I'm gonna have a play at biamping, since i have two Marantz PM6010OSE's, and wanted to know what people thought the best way of doing it was.... i'm think that i have CD into amp 1, then take tape-out from amp 1 into Aux in of Amp 2, and then have Amp 1 drive the Hi of Speaker 1 & 2, while Amp 2 drives the Lo of Speakers 1 & 2.

anyone have any thoughts in this setup, or can suggest an alternative/better.

btw the Pm6010's don't have any sort of pre-in/out.

cheers
