I just bought a set of Infinity 60.5cs (fronts) and 62.5i (rear) speakers. In your opinon, what would be the best way to power them? I've had a few guys comment about a 2 chan for the components and leaving deck power to the rears. Others say a 4 chan cause RMS ratings aren't much diff (90 and 70). It would be nice to get some real pro input before making a decision (I don't hold too much faith in what some of the say). Oh and I'm hoping to spend around $300 or so.
