[QUOTE="gunz4me, post: 5710113, member: 596464"] I still say your meter probably can't read voltage above the average AC household frequency which is between 50 and 70 Hz... Actually 60 Hz if you want to be exact! Place the red lead in the speaker + and the black lead in the speaker -, tighten down, play the tone, then read the AC voltage. As I said before, try it with a 50 or 60 Hz tone, and if it works you are in business. Try it again with a 1,000 Hz tone, and if it doesn't work, your meter can't read outside the normal frequency of AC current! Just remember, all processing should be disabled and all speakers should be disconnected when doing the DMM method. When I say processing, I mean no crossovers enabled, loudness off, bass and treble set at flat, etc. [/QUOTE]
