Bought a Clamp

[CLRagland1]

So, I bought a DMM and a True RMS clamp. Am I supposed to measure AC or DC, and what are the proper calculations to calculate actual power??

Here are several things to help....

I watched the vids, and just for clarification, I understand how to clamp the positive wire and that is to measure ac amps, and I also measure the ac voltage that the speaker is receiving; and I multiply the two together to find the wattage, correct??

Yes.

Amps x voltage = watts.

Voltage / amps = reactive impedance.

Note: if you have more than one positive speaker lead, you need to clamp all of them together.
