warf: my bad on the 4 ohm rating. Got in a hurry. Good catch!!!

But, they omitted the word simultaneously. Was it on purpose?

And, they have "FTC." If that is the Federal Trade Commission, then I think what they are trying to say is that they are only driving 2 of the 7 channels to full power for 5 minutes. At least that is my understanding of the requirement. Maybe someone can comment on what the "FTC" requirements are and how they apply to this amp. Maybe I'll look for a link.

ON the 770, outlaw specifies RMS. That is a good, solid specification.

Now, how does RMS compare to FTC? I'm not sure. It could be an apples to pears comparison.

I'm not trying to bash outlaw or the 7100, I'm just trying to understand the specifications.
