i generally try to hold close to 0 degrees, but it's worth playing with, as altering the phase can change how the subwoofer interacts with the other speakers as well as the environment it's installed in--the goal is to make the subwoofer blend with the front speakers in a way that the bass sounds like it's in front of you. sometimes everything plays better at 180 deg out of phase. also important to note here that typically, each increase in crossover slope(6db, 12db, 18db, and 24db) will shift it's speakers 90 degrees away of the original phase.

there's a billion different video's on setting gains. i tend to ignore all of them and generally set it just about half most times...
there's a gain/volume adjustment in the head unit to allow easier blending/adjustment of the sub output. "season to taste"

But how does the sub's 'default' rolloff setting influence the rolloff set on the head unit?

personally, i generally set the amplifier crossover settings to a minimum 'failsafe' level just in case i seriously mess up the head unit settings, so i don't have to worry about messing up speakers.
