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.

You need to look at the voltage data on the rear of the amp or manual & see what the maximum wattage consumption/draw is.
Should say something like 120V, 60HZ, 950 watts. The 950 is max draw in my example.
