Dumb question!

How do I find the DCR of an amp?

[JimJ 11]

DCR refers to the DC resistance of a speaker's voice coil...

Do you mean output impedance?

[Schmuck 1]

did research the amp is not where I need to look for DCR but I still could not find a formula to find the DCR. My bad about the amp part.

[Schmuck 1]

yeah

Just put a multimeter on the terminals, positive to positive and negative to negative. There should be a little marking on your meter with the Greek letter omega, that'll be the resistance setting, then adjust the scale accordingly if you don't have an autoranging meter.

FYI: Omega looks like an upside down horseshoe.
