When you buy speakers, the listed power rating would be for each speaker. So with this in mind, I would purchase an amplifier that puts out close to 100 watts RMS per channel @ 4ohms (does not have to match exactly) without going over. With that, you should have clear and clean power running to your speakers. Trying to match the peak power would mean that being loud could sound distorted and that is nothing to look for when listening to music. Hope this helps!
