You drive 2 channels of the amp with the left-channel signal and you drive 2 more channels of that amp with the right-channel signal. Two outputs for EACH of the right- and left-channel signals may be available on your processor/preamp, in which case you'll need 4 pieces of IC cable. If not, go to RadShak and buy 2 1-to-2 RCA adapters (female-to-male) to use at the poweramp; then you'll need only the 2 pieces of IC you're already using.
Of course you'll have to use 2 pairs of speakercables, where there are only about a million choices. I suggest you start inexpensively to determine if you can hear any benefit to biamping.
I actively biamp my Eminent Technology 8s (with a pair of Quicksilver V4s on the MR/Treble and 2 channels of a 7-channel Outlaw 770 on the bass) and passively biamp my centerchannel ET12 and dipolar woofer with 2 more channels of that 770.
Good luck.
BTW it's 'biamp' and 'biamplify' and not 'bi amp' or 'bi-amp'.
