Vandersteen 2WQ set-up for Bi-wire?

I have Mono-Block amps setup via Bi-wire to Northcreek Rhythm speakers and want to know the proper way to hook-up my Vandersteen 2WQ Sub. Do you just hook it up to the amp speaker output terminals designated for the mid to low bass frequencies or do you have to hook it up to all four terminals on each amp? Can anyone help?

Thanks!
