How do you set gain on amp when HU is powering rear deck?

I want to set the gain on my amp (which controls the front door components), but my head unit also powers and controls the volume of the rear deck coaxials.

Should I turn the gain down (which mutes the front components), jump in the back seat and turn it up until the rear deck speakers sound as good as possible without distortion - then leaving the stereo at volume 17 (which is where the rear deck sounds as good as it's going to get for the loudness - raise the gain on the amp to meet that level so they're about equal? I don't know if it matters, but I found out my head unit goes all the way up to 35.

Is it abnormal for me to be able to turn the gain 85-100% up and still not hear any distortion in the speakers? I'm using an 80 RMS watt per channel Rockford amp (actual spec sheet list is about 110 RMS watts) on 80 RMS watt Boston component SL 60s.

Just from what I read, the gain should be "around" half way or a little bit more. Well... I have to turn my gain at least 85% up to have the front components meet the sound intensity of the much lower rated speakers in the back. Does any of this sound fishy to anyone?

The installer put the amp (which again, is only powering "full range component speakers = no sub) on all pass, not limiting any frequency to these speakers. Does that sound right if I don't have a sub?

When I'm doing all this, should I turn off the BBE sound enchancer and bring the fader (front to back) to 0?
