So I've been bumping two American Bass XD 10's powered by a mmats 1400.1 amp. I think I just burned up one of the subs so I obviously want to replace. I want something louder. My system hit 153.2db and that's with two 10's. I like American Bass's products but the VFL's are 1500wrms each and I don't want to buy another amp. I'm looking at the Fi subs and specifically the IB3 12's. Anybody have them? They're 50wrms each more then XD's (500wrms each). The amps 1400wrms @ 1 ohm so I don't want anything that's more then 650wrms each. Reccomend another sub? Thanks =)
