Bi wiring?

FYI: Technically, you are asking if you can "Bi-amp" your speakers, not merely "Bi-wire" them.

Having that much difference in power would probably yield more problems than it would be worth, IMHO. (And I imagine that the power reserves of a dedicated power amp are much greater than a receiver's power reserves, which would only make things worse.) And typically, a dedicated amp has a better sonic signature than a receiver, so you will probably notice a difference in quality.

However, that being said, you can try it and find out. (IMHO, having the reciever on the top end makes the most sense.)

Good Luck, (and let us know how it turns out if you decide to try it).

Correct, that would be bi-"amping", not bi-wiring. You would still need some way to control the outboard amp. Either level controls on the amp itself or an outboard crossover. Since the power ratings are so different, you'll need to balance them out.

Usually, biamping involves the same amps or running them through a crossover.

Since the power ratings are so different, you'll need to balance them out.

Since the voltage sensitivities are probably different, you will need to find a way to balance them. Power output capacity is irrelevant.

BTW, if the 300wpc amp is a good one, it will do just fine alone and without biamping. You do not need to have an amplifier capacity equal to the speaker's maximum rating.
