[QUOTE="zako, post: 8013831, member: 629735"] Do not be obsessed about having to run >100watts of power. My suspicion is that most speakers do not really handle the rated power specially when crazy numbers are given. The power handling spec is thermal limit, but most speakers will easily run into excursion limit at low frequencies with well over 100watt RMS. Another issue is that THD can go through the roof if you actually drive the speakers hard enough to make use of those 100watts of power (speaker THD, not amp THD). At the same time having too much power can't really hard even when listening at normal volume level. You get more heard room for dynamics and lower amplifier THD. No problem IMHO. If you're worried too much, get hold of a DMM and set amplifier gain by DMM. Regarding amplifier, if you're going to drive subwoofers and speakers with one amplifier, get a relatively high power 4-channel amp, as the more power is normally better for the subwoofers. I'd mention the PPI Phantom P900.4 too. This thing normally costs $200 online. The value is incredible. You get respectable 450watts on bridged channels, small case, and the thing never runs hot.
