Nope. If your short on power you need a seperate amp. With your avr that would be a 300wpc amp as you have a good amp section. Biamping off your amp would still be the same power supply, so no additional gain.

The 4520 can't active bi-amp either unless you use external amps and an active crossover; it's just passive bi-amping and like everettT says, same power supply so no real benefit. Try this article https://www.audioholics.com/frequent-questions/the-difference-between-biamping-vs-biwiring
