I am using a DSP and I have set my amp gains at -5db for midbass, mids and highs and -10db for sub bass. I have many many bands of EQ I can use (RF 3Sixty.3) and I am having a brain fart. Please someone clear this stinker of a fart up for me. I always "EQ" by reducing each band from 0db. If I am at -5db from the get go... does this mean I can safely boost to +5db (Technically 0db) on those bands of the EQ without distortion? Is this the "headroom" people are talking about? Up to +10db on the sub? Someone clear this up for me please. It seems like my system should be louder than it is... not that it is quiet.
