So me and a friend were testing our ohms on our subs. He has a j audio w7 and I have 2 Rockford fosgate p3 the w7 being wired at 3 ohms and the rock fords being wired at 2 ohms when the amp on the w7 is off the sub reads 3 ohms on the dot as soon as the amp turns on it moves up to 6.5 ohms and on the Rockfords when the amp is off it reads 2 ohms right on the dot but when the amp turns on it drops down to .5 ohms. Does anyone have any idea why this is?

Subwoofers are not a fixed ohm load. They will change up and down based on what you are playing.
