ok 1222d is a dual 2 ohm coil , that amp should work if you are just doing one , what you want to do is take one jumper wire from 1 red to 1 black , that should leave you one red and one black open and take that to the bridged output of your amp and it should work good , if you are running 2 subs you dont want a 2 channel amp you want a mono amp , lemme know how it does
