Meter Amp outputs

What setting on my meter should I use to check the speaker terminals on my amp for the correct output? I'm having an issue with my front left channel on a 4 channel amp.

Voltage. And have the meter set for something over what you are trying to read.

Thanks miker. I am reading .14Vdc on all the amp speaker outputs with the meter set on 20VDC. I narrowed the problem down to what must be my LF speaker wire from the radio to the MTX re-Q5. I waited 2 weeks to have the re-Q5 replaced thinking that was the problem, plugged in a new one and the same problem still exists. I swapped the LF and RF speaker leads at the amp and the problem followed, I switched the front channel RCA L to R from the re-Q5 to the amp and the problem followed. Then I switched the speaker leads from the radio to the re-Q5 and the problem followed. My soldered connection on the LF speaker wire at the radio must have failed or the speaker wire itself was damaged somehow under the carpet. It will take another day to research that. Thanks.

you'll want to use voltage ac not dc for speaker terminal out put
