dmm amp setup

[vincer20 0]

i have been trying to set my amps but am not getting a good reading im always getting 2. some odd volts then when i turn gain up i get OL. i was thinking since my amp is a pg xenon 600.1 that i would not be able to set it because the amp detects the ohms while the speakers are hooked up, i think thats how it works.
