i searched around and couldn't find much of exactly what i was looking for but i did find this(i added the quotes)this came from a passive bi-amp statement.

Unlike bi-wiring, """the load to each amplifier is different from that using a single amplifier full range.""" The voltage demands on each amplifier remain the same (each is still fed a full-range input and gives a full-range output), but the current demands are reduced. This of itself can improve the amplifier’s ability to deliver the signal to the speaker.

Be careful when bi-amping that the gain and polarity of each amplifier are the same, otherwise you will compromise the frequency response of the system.
