LP is fine
Not sure about the SS, box is at 32 so I'd put it at 26-ish but you also have x's so they take lows really well. Idk about it, not really knowledgeable with SS filters and how to use them with box tuning. I've always just put it 6-8 down from the box once the subs are broken in.
In that picture is the gain all the way down? Turn that sucker up
Bass boost should be at 0 and stay at 0 forever.
We will fix this my man
