Alright guys, I tried it again with the subsonic filter set to 5hz (lowest), LPF set to 400 (highest), bass boost at 0, and gain was at exactly half. I tightened down the DMM's leads into the speaker wire outputs. The head unit was at 50/62, loudness off, no EQ settings, etc. The bass knob was all the way up. I played a 0dB 50hz 192kbps (only bitrate available) sine wave from realmofexcursion.com that I downloaded to my iPhone. I set the DMM to AC volts. Reading = ~ 00.21 volts. What am I doing wrong here!?
