If the Rotel doesn't shut down at 3/4 volume then that tells me the Emotivia is a defective unit. The Yammie just isn't up to the task and not a receiver in which Axiom recommends for the M80s.
It's not your wiring, do you use a microwave? Does it shut down? If not then don't worry about the wiring, that takes far more amps and is harder to run than the amp.
