I was messing with the gain on my sub amp with a dmm tool. I realize some people dont like to use a dmm for setting gain but i was just curious what mine was doing. Anyway, at 3/4 gain I get 35.9 on dmm. Now my amp is supposed to be rated 360 at 4 ohm. so according to the formula i come up with 37.94 So does this mean my amp is not doing what its rated for? And also more importantly, if i turn the gain up past 3/4 it drops to like 32-33 so does that mean that 3/4 is right at its peak before clipping? I have 2 12 inch planet audio supposedly rated 180 each. I dont hear any distortion no matter where it is set.
