Bass Boost & Remote Bass Control on Kicker Amp
Okay, time for another one of my dumb questions. My Kicker ZX700.5 has a bass boost control knob on the amp and a remote bass level control knob for the sub channel (channel 5). The manual says that the bass boost control knob gives increased output (o-18db) at 40 Hz. So increasing this knob increases the volume of sound just at 40Hz? Or 40 Hz and below? So why would I want to turn up just this part of the frequency/frequency range?
I also have a remote bass level control knob. Is this a separate volume control knob for channel 5 and is different than either the bass boost control knob and the input level (gain) knob on the amp?
Finally, how do I set the gain on channel 5 - should I have both the bass boost control knob and the remote bass level control knob at zero when I set the gain? If not, where should I have them set when I set the gain?
