I have 3 of these subs in my yukon running on a rf bd1500 1 at .75 ohms. Each sub is getting a lil over 2100 watts absolutely clean and loud. there is a reason JL has not changed theses subs in 10 years there is no need i play at full volume all the time an for the first time in 6 years i blew one. 365$ to jl and i get re-coned back in business all i can say is this sub is the best sub ive ever heard. There are alot of other subs out there that claim to be louder an most of them are 18's an need 6000 watts. I promise 3 jls running on 2000 watts each is gonna be louder then any 18.
