[QUOTE="SlowLoudNBangin, post: 6378307, member: 614817"] now when you say " i always use my O'scope when testing the output..." are you just talking about the setting the gain part...as in checking for clipping...or actually finding the constant output of amp by only using scope? cause i want to do the same thing, measure the RMS output of my amp, but i only have a o'scope, im gonna get the clamp and DMM soon though, whats crazy is i got a EZdigital 5060a 60MHz 2channel scope in perfect working order for 10bucks from my school, and i know it works cause i tested it myself. im in my 7th quarter at ITT tech for electronics...love it so im pretty sure im not going to be able to do this since im going to need a clamp meter for current, and a DMM for impedance, cause P=IV, but what about the equation P=(V^2) / ®.... which is the same thing, could i square my voltage and divide by my sub load...anyone ever found it that way? or am i SOL and theres no possible way to measure RMS wattage with only an O'scope... thanks in advance for any advice.
