ohmage vs. wattage?

looking for an amplifier to power three 10" eclipse aluminums rated at 400w/800w wired as a 2.6 ohm load. how much power would a 1200w @ 2ohm amp put out running a 2.67 ohm load? is there a calculator somewhere?

well it makes 1200 watts at 2 ohms and like 600 at 4 ohms then just figure out the middle of that and a then the middle of that again. so around 1000 watts roughly

They will receive roughly 400 watts a piece, probably a little less, but there won't be an audible difference.

I assume the 800 watt rating is peak? Use the rms numbers on both subs and amps.

No calculator for this that I know of.  It's just simple math, though, but write the results as you go through it.  You know what the rated output is at 2 ohms.  Now look at the rated output at 4 ohms.  Subtract the 4 ohm from the 2 ohm.  Divide that answer into two, and then add that result to the 4 ohm rating.  You now have an extrapolated 3 ohm output.

Compare the 3 ohm to the 2 ohm outputs.  Divide the difference between them by three to get  thirds.  Add one third to the 3 ohm output to get a 2.67 ohm result.

You can't extrapolate another "rated" output from only one given rating...but you can come up with a good guess as long as you have two ratings to work with.

heh heh....or do like wrathchild did and come up with the answer in your head.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

was never real good at math but i got it figured out.

given:
600w @ 4ohms / 1200w @ 2ohms

couple notepad scribbles later:
900w @ 3ohms / 1000w @ 2.67ohms

thanx again.
