I put it on AC this time and I got some type of a reading. There were a few strange things though that make me think I'm still doing something wrong. 1) I need to have the meter set on mV to get a reading anywhere close to the 31.62 I'm looking for, although the number DOES rise with upping the gain and I also tested it with a song to make sure it happens when the bass hits, which it does. I get a reading that looks like this, " ~ 031.6 mV " 2) I played a song with the gain set like this (and the gain was at about 1/5 of the way up) and it was no where near what I was used to hearing 3) It was originally set by a car audio shop, so I set it to where it was before I started fiddling with it and the meter was reading UP TO " ~ 080.0 mV " or so on bass hits in some songs like Smile Back from Mac Miller These things lead me to believe I'm still doing something wrong.
