Im more confused on what to get know, then i was at the bigining. Im will be using a Hifonics colossus to power the subs at 1600watts rms at 1ohm x 2ch. Maybe this will help u suggest a sub. BL's , 13w7 SI MAGs?????????
i can only comment on the w7's has i used to own 4 of them and you wont be unhappy trust me.. if you do go with the 13's throw about 1000 watts to each and your good to go i mean if money is not an issue im sure many would take the w7 if your tight on cash go with the fi.
