This might prove to be a dumb question but im having a hard time finding a solid answer on this one. When tuning an amplifier for subwoofers, should you set the bass knob that the amp comes with to half way or all the way up? Some say to set it half way when tuning knobs on the amp but im concerned that if i do this, then later decide to turn it past half way up, i will get clipping/distortion and blow the sub, considering it isnt a volume knob but more like an external gain knob.
