Alex, most anything will work. The trick is to get something with some headroom so you're not maxing out the amp. If you daisy-chain the 2 speakers, then you will have to worry about the Ohms. We use QSC Amps in our band, with great results. Many other good ones are available.

Im just not up to date with P.A terms

if it says 125 continuious

then should my amp be 250 watts mono

does 250 watts mono mean 125 per side?

does 250 stereo mean 250 per side....im just not sure

It means 250 "Peak", which I believe means when you temporarily peak the speakers, it will take up to that much. Program, or "Continuous" is what they are meant to be run at.

Steve is correct.

The only rating that really has any meaning with speakers and amps is RMS. All others are arbitary and misleading. Any speaker that is rated in RMS watts can be compared to any other speaker rated in RMS watts. A good amp or speaker will say 250 WRMS continuous, which means that they have run a certain tone through it at 250 WMRS for usually one hour.
These ratings were not used for a number of years as they are so misleading they are virtually meaningless. I think they were actually outlawed if I remember correctly. It is now possible to buy 1000 watt boom boxes, haha!
with an amp you want to also know the distortion specs, should say 250 WRMS continous at .05% distortion, now that tell you something specific. Peak comes from peak to peak, continuous by itself usually comes from music power which is running music through the equipment instead of a pure tone, and both are baloney as far as rating amps and speakers goes. The efficiency which is how loud a given speaker is for a given amount of power is rated in DB, usually for ex. 97, etc. db @ one watt RMS.

Oh, your speakers are probably rated for around 100 watts RMS.
