I have an amp that's gain volts need to be set to 31. My question is when I set my bass boost should I keep it at halfway before setting the gain. This way I can turn it down for songs that have too much bass and up for songs that I want more bass in. Most people say to set bass boost to zero when setting gain. If I did that though I would not be able to turn down sub for songs that the sub would have too much bass in such as rock songs.
