do you have the + and - speaker wire right next to each other on the amp or one on one end and the other on the other end?
use the 18 or 24db xover setting. or just dont use it at all and use the amp (which i prefer) and set your gain using a -6db 50hz test tone with your subwoofer level @ +15. alpine subwoofer preout is rated at 4 volts @ +15 instead of at +0. kinda weird but eh.nope sub level is like 6 and the x-over setting is at 6 db out of 24 db... there is no excursion at all, they just kinda vibrate...
