Reply to Confused with watts/ohms! (amp)

Hi, I am putting together a little system for my house and parties, but amps, ohms and wattss are giving me a headache.
I have purchased 2 x 300 RMS, 8 ohm speakers:

But have looked through many threads and everyone says different things about amps, is there anyone who can give me a definate answer for what amplifier wattage/ohms e.t.c I need? or recommend any amps?

Thanks.
