SOMEBODY PLEASE HELP!!!!

I have a btl 15" fully loaded and an american bass XD3000 [email protected], and i was wondering what yall think i should set my subsonic,lowpass,qbass, and phase shift at to get the most out of my sub.

You only need the subsonic if you have a ported enclosure.

The Lowpass you should set to where you like it, personally my subs are crossed at 50Hz but most people like to run them higher at the expense of localization though.

Phase shift will be completely different for every installation. Try it both ways and see.

Never used or seen a qbass adjustment. I'd prefer it flat if it is some sort of bass response profile/boost.

my phase shift is nob i dont remeber what number is goes to tho and what is localization??

phase shift is 0 or 180, localization occurs at around 100hz, its when your ears can determine the source of the sound.

You can localize much lower than 100hz.

anybody else have any input on how i should set my settings?

Listen to what you've been told, it's good advice.

I would set it as low as your front soundstage can handle. like 63 or 80 hz.
