case: i understand ohm's law.But amplifier have reserves that are a result of capacitors... and i know that the 770 has a better uf ration per 200wchannels than the m200.

alejate: I am searching for exactly the same info that you provided for the h/k model but for the 770 and the m200.not wether its relevant or not...
I'm glad you like the power of the 770.For all i've read on the subject, 770 customers are all glad they bought the amp... I intend to use 4 monoblocks to power 2 12" dual-voice-coils (each 4ohms) and current available is a concern in my mind.I'm currently using two pa2000(130Wrms on each coils) and the subs are still asking for more...Anyway, 7 paid monoblocks are to be shipped as soon as the "infamous" ups canada strike stops.
