I know my new Onkyo 606 can bi amp speakers. I have a pair of Definitive BP8Bs that only have one set of speaker posts. Is it possible to still bi amp these speakers thereby giving them more watts? I know in a usual setup you are suppose to have a pair of speaker terminals but is it possible with one set without damaging the speakers? Would it then provide 180 watts to each speaker instead of just 90w?
