I don't think they could last as a manufacturer, if they could not
put out when cranked. Thats what they were built for. If the max power
is much more than you need, the unit should also have not problem putting
out less watts. If you have some desire to generate rumbling at 20 Hz,
it will probably work anyway.

Thanks Greg, but I doubt most people couldn't easily tell the difference, so
that's why the specs are so critical when comparing performance. If the amp
can do the job the specs would reflect that, or I have to assume it probably
can't.

Most all the time, just derating the power will make everything fall into place.
If you can stand maybe a 10-15% reduction in the power spec., then all
should be fine. The distortion levels also fall dramatically. I assume both channels
are tested the same time, just like home amps, but I'm not 100% certain.

The XLS amps seem to have heftier power supplies than the old PowerBase series, in that the
power increases more in porportion to the load impedance. I have a couple of the PB2's.
