Short answer-Yes, but:
That amp is considerably underpowered for that purpose, I'd want around 750w per channel at four ohms to drive those. With that output, you'd only be putting around 350w into the KAMS, which is far from excessive.
Also, don't expect a huge increase in perceived volume, it won't happen. Been there................................
Thirdly, thanks for all the info, but names and power specs would have been sufficient.
Fourth, I see the amp has figures for running at two ohms. Unless it has certain very expensive badges on, and you really really know what you're doing, regard this as forbidden. ( Waits for someone to recount how they've run their EP2500 in this way countless times with no ill efffects. )

Thanks for response what do you mean by the above would it be worth doing this ? Or am i better off just running the XLR speakers
Thanks again

Peter means, I think, that when people double the number of speakers they're using, they think they're going to get double the sound volume. It doesn't work like that. To get more "oomph" in your output, it could be a simpler solution just adding a bass bin.
I tried to run 4 speakers off a single 1200w amp and had some problems despite the specs and associated maths suggesting it should work. Now if I'm running multiple speakers, I take feeds off the mixer and run multiple amps.
