not supposed to pull the rca's too ,just the speaker wires
DMM should be on Volts AC. NOT volts DC.

ok my bad
I found with my mac tools unit that it needed a good hard connection i actually had to put the leads of the testers in the speaker wire clamps on the amp and tighten them down to get the correct reading.

Alright, so I went out to try to set the gain again. 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. Can you help me?

I did clamp them down with the set screws actually. And I'm still getting the type of reading in the post right above this one.

On your amp, turn your low pass filter all the way up, turn your subsonic all the way down, turn bass boost off. Make sure your tone is recorded at 0db. Try it again.

That's music. You're wasting your time measuring the voltage on music.

you need a test tone for setting gains

I did use a test tone first. 50Hz sine wave. It was reading under 1 volt no matter how far up the gain was. Like I said, at 1/5th gain (using the sine wave) the meter read 31.6 mV

maybe it was a bad file somehow. Can someone link me to a good download? I'll be using it off my iPod.
