Ed said ideally that you want it to come back at around -7-8db and then if you want to run it hot go down 3db. Ex: if it sets it at -8db then if you want to un it hot go to -5db. He told me to set the gain at 1 o'clock and then run MCAAC again.
. On my own I also noticed that the speaker distance setting for the subs was off by a couple feet. I changed that but i am not sure what effect that may have had on delay settings, reverb, etc that the receiver MCACC set. I have a SC25 and I asked them why the sub distance was a few feet off and they said that it accounts for a delay. They said to just leave it. @jnoel
