Everyone here is right, you should do some research before you buy, but since i have been doin this for a couple years now, some of these guys are close and maybe even right. There is a problem when it comes to the square subs, bigger box is not always better, the way there designed is to run usually 1.5 cf to 7.0 cf, so if you got sold a HUMONGOUS box im sorry, and the thought of one 12 hitting harder than two 15s is kinda out in left field, maybe if the 15s dont have enough power, yeah but i highly dought that. Dude i work in that industry and i know about getting the money out of people but i have done a lot of research and if you want to be loud get the 15s, hook it up right and boom-on.




two crossfire 15s on a Hifonics with 3200w and a 1farad cap, loud but not loud enough
