I have a little bity of a decision to make because i have a Alphasonik PMA1200DA amp and i also have 2 12" Power Acoustik MOFO series 2400 watt subs and than 2 15" Alpine Type-R 2000 watt subs. Im bout to get my box built and i cant decide whether to use the 15's or thw 12's. I basically want it to be loud as hell!! I mean sound quality i do care about a lil bit but i basically want to compete soon so i wanna see what everyone thinks on which ones i should use!!
If you can custom build the box to the specs of the subwoofer then do so. and make sure it'll fit in the car. Another option you have of doing is what Chauncey said in one of the other forums to you. sell all that stuff and get better equipment. I think that is the "best" advice you can get. We can definitely help you get a better system if your willing to dish out some extra money.
yea i was thinkin bout keeping them least for a while!! But i dont know i was looking into the Cerwin Vega 15" Strokers!! I dont know what are some loud loud 15"s that arent insanely expensive?!?!
