Let's belabor this a little further. Here is the FTC link to changes made in the year 2000.

FTC changes

I find the following most interesting;

"allow the subwoofer and satellite amplifier sections in combination self-powered speaker systems to be driven to full rated power separately, rather than simultaneously, during the power rating tests."

Bottom Line is that I really don't think that your 7100 is rated at 100 watts for all 7 channels simultaneously.

Hope that this helps! I believe that it helped me better understand the outlaw specs.
