Was adjusting my gain this morning using a dmm. Now keep in mind I have a Pioneer DEH-80PRS headunit. Had my volume set to 47, eq set to flat, and had a 40hz note set on pause. Went back and set my amp gain to 0, sonic filter off, sub filter all the way up, and no boost. Put my dmm to V/ac and have it red to positive and black to negative speaker outputs. As soon and I unpaused the music I was at 34v/ac for about 1156 watts. Now I wanted to set for 1200 watts or 34.64v/ac. Hardly any gain adjustment. I was just surprised. Has anyone else used a dmm to adjust this particular amp???
