[QUOTE="Kangaroux, post: 7394475, member: 628495"] To test for impedance switch the multimeter to the omega symbol Ω. Red test lead goes to the positive terminal, black goes to the negative, obviously. To test for output, or to set your gain, you switch the multimeter to AC voltage (shown usually as a sine wave). Check for power going to the amp or for a faulty ground, switch your meter to DC voltage (shown as a line with a dotted line above it). You can also switch your meter to continuity to check and see if a circuit, voice coil, or fuse is blown. No need to match up leads, just put them in the 2 spots you want to check and the meter should make a beep noise. Don't check for continuity if a circuit has power running through it though because you can short it out with the leads and blow a fuse in the meter. As for testing how much an amplifier actually puts you would need a rms clamp meter which operates differently than a multimeter does. [/QUOTE]
