paradigm studio 100 v.3 and anthem amps

i am new to most of this as i just purchased a pair of studio 100s and have an anthem mca 20 driving them my question is i also have an anthem mca 30 that is not being used could i use 2 of the chanels from that to biamp the 100s. i know the watts are different in 10 for the 30 and 200 for the 20 but i think that if the gain is the same it would work any suggestions because i know these 100s really could use the power thanks,mike
