Great thanks for the advice Alan! Two of the outlets are labeled "hi current" and the manual states they do not limit current draw so I assumed that I should
plug it into that port. However if Axiom recommends against it and the amp will be good and run better without doing this all the better (I don't need that long cord afterall). The PC is a Panamax 5100 BTW.
Axiom advises against plugging its subwoofers and amplifiers into power conditioners, as the latter may limit current/voltage and cause problems with the subwoofer operation.
Besides, as JohnK will likely point out, the power supply of the subwoofer amplifier does all the "conditioning" required of the incoming AC signal.
