amp power

i just have a quick question, might be stupid but w/e...here goes anyways...i saw at Here that this will tell you the watts comming from your amp. well i decided to test mine and i got 111 volts, and by doing this equation it says im getting 32423.68 watts at .38ohms
which is rediculous IMO, so im just wondering if i did this wrong or if this is an innacurate way of doing this or w/e....just curious, thnx

well i have 3 10's and 1 12 on one line giving me 0.7 ohms, and 4 12's giving me 0.8 ohms....so if i assume 0.75 each, then that in half is 0.38 with the 2 loads...i could be wrong and possibly misscalculated that terribly, but one load is 0.7 and one is 0.8, so im pretty sure its .38....but yea, i know its not making that much, i was just curious why that is saying that....is there any other way to figure it out?...it was staying at 111 volts for a while so i used that number...any help would be great...thnx
LOL so you are running all that on your orion.. .373 ohm by my calculation...
(or about .5ohm on your '1' ohm stable amp)
well your average dmm is going to take the peak voltage/1.41 so depending on the response time of the meter who knows what you are getting... clipping can cause insain peaks in voltage at high frequencies & impedance
(the better the response time, the higher the #
)
For true #s with an ordanary dmm you need to use sinewave.. if you want dynamic power you could set up a test signal according to the response time of your meter and you have to know the exact impedance @ test signal frequency.. (via wheatstone bridge)
Otherwise you should use a RMS dmm and an RMS ammeter... you can measure 'dynamic' power as maximum output over the average responding time of the meters...

0.35ohm best for burping at.
