difference between 8ohms and 4ohms and voltage con


I have an amp that is supposed to run 160Wpc at 8ohms and 320Wpc at 4ohms. I am just wondering how I know which it is running at? I am moving to New Zealand where the voltage is different (240 rather than 110) so need to get a converter that can handle that wattage. I am wondering if a 550W converter would be able to handle the amp. Any advice would be appreciated.

I understand that 8 or 4 ohms will make no difference but it may for the converter and then ultimately for the amp. A 550W converter can handle 160Wpc not 320Wpc. If the converter cannot handle it, it will fry the amp. Anyway, I will check my speakers to see. Thank you.
