I have a alpine MRD-M301 amp with digital settings and a 12inch alpine type-s sub in a ported q-logic box. The amp has lots of confusing settings and i need help from you guys on how to get the most of them. Can anyone explain what LPF, Subsonic filter, and parametric EQ do? I couldn't find an amp setting tutorial on this site, but if anyone has seen one, please post the link.

(the instruction manual for the amp simple explain how to adjust them but do no state what difference they make.)
