if you got it set up on your headunit there's no need to set it on the amp too, just set it to around 80 or off if you can

no point in using to of the same filter so set it on the headunit and turn it off or all the way up on the amp

Correct. All the way up to me is preferred. Remember, you'll be adding the slope of the amp if you can't go to "full pass"

So your hu slope and your amp slope is combined. I like ALL PASS or up full.
