He already turned the gain up all the way and it didn't make it any louder. What's buying a dmm going to do for him?
that's what I was getting at, just because it didn't get louder doesn't mean clipping didn't increase.Set his gain right. The gain is meant to match headunit preout voltage. Its not a volume knob.
