No, you can't, because if you did it would mean that you haven't done a simple search and read about 1,426 other threads where people have already responded that there's a greater than 99% chance passive bi-amping will make no audible difference. If you want to do it anyway, just because you think it looks cool, and sounds like you've done something cool to your friends who don't know any better, go for it. But don't tell anyone here about it, lest you get castigated for silliness.
