Hi, I have a temporary 4 channel amp installed until i get the money together for my new amp. Two channels runs the sub and the other channels run the components. I have set the gain to approx 3/4 for the sub channels and 1/2 for the components. I also have a bass boost setting on the amp. What do you guys recommend i set this to for the sub channels? I Currently its half. (The bass boost is 0 - 18 db and i want clear deep bass). Thanks.
