Welcome Mears! There aren't too many of us Denver-Metro area guys here.They are rated at 50 watts RMS (200 peak). I'm debating between two same brand amps, one that puts out 75x2 and another that's 125x2 at 4 ohms. Would 125 watts per channel be too much for these to handle?
Get as much power as you can afford. Once you've read up a little, you'll learn that watts directly correlate with volume. As long as you're listening to reasonable volumes, you won't cook your speakers. The problem comes from people using low powered amps, cranking the gains and driving the speakers with a significantly clipped signal.
