Can you measure the impedance of a speaker cabinet with multiple speakers at the input jack ?
You can measure the DC resistance at the jack. It will be slightly lower than the rated impedance (e.g. 8 ohms impedance might read 6 - 7 or so ohms DC resistance).
EDIT: If you can't easily get at the jack, @laristotle 's approach below will work. Using a short cable is best.
Plug a cable into the speaker jack.
Hold the multi-meter black tip to the sleeve of the jack at the other end of the cable, red tip to the tip of the jack.
Separate names with a comma.
