which should i use for the lower frequency? the 640 or the 540? - the manual says use the more powerful amp for the bass, do you guys agree?

I would follow the manual to begin listening for a reference. If you then want to switch the pair of amps to other functions, you'll know what you had according to the manufacturer's recommendations.
