what do you mean?

 

[andar 10+ year member]

if you mean volts its sqrt(watts*resistance)

Watts=Volts X Amps

AC voltage and Amperage of course.

no no i'm trying to find how to determin exactly how many watts the amp is putting out at X amount of voltage i think it has like a variable for ohm load and voltage output...

You must have an Clamp Meter, and a true RMS DMM to measure amplifire output.

a clamp and a DMM? that sucks i thought i remembered seeing a formula somewhere where you use a volt meter on the amp output and plug it in to a equation which has ohm load as a variable... there is no such thing?

yeahi was wondering if you could do like a "bench test" on an amp too w/ a DMM, but i don't think you can.

i read on here that a guy paid $10 at a local shop and they did it for him w/ an oscilloscope and a dmm

you need a clamp meter to get AC amperage off of the speaker leads.

Why do you always ask the most ridiculous questions?

if its so rediculous then don't waste your time replying, to everyone else... on page 11 of http://www.bcae1.com/ there is a calculator that uses the formula i was talking about, anyone know what this formula is?

Hope that helps

don't you have something better to do?

hahahaahaa i thought it was real till i got to the end my calculator says syntax error
