Reply to power converter question

hi i brought some speakers from the us and now i need a power converter. i have two elx 115ps and one elx 118p. the 115ps are 1000w each and the sub is 700.

say i buy this power converter for my two 115ps

will 2000 watts be enough or should i have a little over but in saying that the next step up is 3000watts. same goes for the 118p sub. but with the sub i can not find a 700 watt converter the closest i found was 1000 watt

thanks for your time
