[QUOTE="Savant, post: 190005, member: 546108"] K.. here is the deal.. the amp provides a certian 'upper limit' based on what the resistence of the load is.. Normally, as the resistence goes DOWN the total upper limit goes UP.. So, the ratings are based on the load... That is, you amp can say it's 200 rms at 2 ohm, but that means nothing to a degree.. what does it say is the rms at 4 ohm? I'm guessing closer to 100 rms.. In that context, you could hook up a 500000 ohm sub to your amp (not really sure it's a good idea, you might blow it immediately or it might do nothing, I'm not sure) and that does not mean you have 200 watts at 2 ohm (because you aren't at 2 ohm.. you 'would' have 200 watts 'if' you were at 2 ohm, but you aren't..).. In general, the relationship to resistence and total avialable power is, as the resistence goes down, the power goes up.. if you "half" the resistence, you "double" the power.. So, in your initial example (200 at 2 ohm with a 4 ohm load) the sub would only get about 100 watts, not 400.. if the amp said "200 at 4 ohm" and you put a 2 ohm load on it, THEN you would head toward 400 watts.. Hope that helps.. [/QUOTE]
