very basically, ohm refers to impedence or resistance. a amp running at 1ohm is wide open so to speak and produces more power than it would at 2 or 4ohms (generally). however,it stands a greater chance of running hot and possible failure. not all amps are 1ohm stable and lower.
speakers are wired in such a way to take advantage of different amps.
here is a great link from which to study.
