Thanks, Bombaywalla. I see what you're saying. The module datasheet shows that when it is operated with 120 VAC it is rated to deliver 600 watts into 2.7 ohms in stereo mode, although with just one channel driven. That corresponding to an output current of 14.9 amps.
While the max rating in bridged mode that you cited of 700W into 4 and 8 ohms corresponds, for 4 ohms, to 13.2 amps from each channel, simultaneously but with the channels being operated out of phase.
A couple of inconsistencies in the numbers, though, which I don't know how to reconcile:
1)The 950 watt figure I cited for bridged mode, for an 8 ohm load, comes from the Rowland site (click "specifications"). That number being even higher than the 900W number that is indicated in the module datasheet for 230 VAC operation, for an 8 ohm load in bridged mode.
2)I would think that the indication in the module data sheet of 30 amps peak output current is likely to refer to the peak of a sinusoidal waveform. (For example, I've seen credible indications that Pass Labs specifies peak output currents on that basis). While the currents that can be extrapolated from the power ratings based on Isquared x R would be rms values. For a sine wave, 30 amps peak of course corresponds to 30 x 0.707 = 21.2 amps.
As I say, I'm not sure how to reconcile all of that. Assuming that the module for which Kijanki provided the datasheet is truly the one used in the 525, I suppose it all adds up to further confirmation of how, as he indicated in his last post, power specs are often not defined on a consistent basis.
