Question regarding my setup

I have a Grand Prix with the following setup:
Head Unit: Alpine 9981
Speakers : MB Quart 5.25 components in front and MB Quart 6x9 in the rear.
Amp: Polk c400.4
This was all installed by a professional company.
I have been considering buying a sub woofer to get more bass, so have started looking at the initial setup on the amp. The gains were both set at about 11 o'clock.
The Headunit is supposed to give 4 volt pre-amp out but the amp had been set to low "signal input". The manual states I should set the "signal input" to High, so I did.
Now I have to tweek the Gains to match the input of the amp.. I have set the gains to around 12 o'clock and have noticed a slight increase in sound, I will keep tweeking making sure not to set the gains past 2 o'clock.
2 questions...
1. Why are their 2 gain adjustments? Should they be set the same?
2. Does the "Crossover Frequency Adjustment" need to be changed in the gain is altered?

I would suggest you post this in the Car Audio and Electronics section. You would get a better response there
