Is it safe to run AVR/Sub/PC on Inverter?

[sameuun]

Hi guys,
i recently encountered a problem with subwoofer, some noise disturbance coming out, like im receiving alien signals , lolz,
I was wondering that it might have gone wrong cuz i recently put everything on inverter or did i miss something, ?

pls help.
my sub is Polk audio PSW110 and its dying, problem getting worse everyday,

I dont think that should be a problem-my HT set up-incl sub runs ONLY off my UPS. It is possible that the UPS has a problem or the sub has a problem, which one needs to be identified.
