What DB level should I be looking at (Fronts compared Backs compared to sub) I have the Pioneer 1014 and when I ran the MCACC, It set each speaker at different DB levels like +4.5DB or +6.5DB. However the sub was turned down to a -9.5db. I started changing all levels manually making each speaker 4.5db but what to I put the sub at?? Please! Lots of help. I'm pretty new at this manual adjusting.
