[QUOTE="Prowler573, post: 2964315, member: 561023"] The major difference is something you yourself already stated. Generally speaking (though there are notable exceptions) you will get more wattage output from your amp the lower the resistance that you present it. (assuming the amp in question is stable at the Ohm load you are wanting to show to it) Almost [B]all[/B] amps will make more power into a 2 Ohm load than they will into a 4 Ohm load. Note that I said almost as there are amps out there (certain JBL units, Phoenix Gold Xenon-series amps, the JL Slash-series amps for example) that make the same power into multiple resistance loads but these are the exception rather than the rule. My monoblock can serve as a good "for instance" ~ Factory ratings (which are somewhat less than actual output but you'll get the idea) on the Diamond Audio D61500.1 are: 375w X 1 @ 4 Ohms 750w X 1 @ 2 Ohms 1,500w X 1 @ 1 Ohm. Many, many other amps operate much in the same fashion. So - in general terms the lower the resistance shown to the amp the higher the wattage ouput will be. Just be certain that once you get below 2 Ohms that your amp will sustain that low of a load. Almost all amps will support a 2 Ohm load dependent on configuration. Once you get to a 1 Ohm load the list of amps that will offer stable operation gets much shorter and below a 1 Ohm load the list is even smaller. [/QUOTE]
