I wonder how much the voltage would have to sag, I seem to remember the volts ranging between 119 and 122 at least according to my meter, probably closer to 119 when the amperage jumped up, I'll have to watch for that, but there did not seem to be much of a significant dip.

Lonnie asked me to try different cables as a diagnostic.

I changed the interconnects, same problem.

I switched speakers to Polk Reference 10bs and the speakers began to pop, crackle, and fry but the amp did not go into protect.

I used the speaker cables that were connected to the Polks to connect the axioms to the xpa 2 and problem recurred.
