To the OP, some how, everybody missed something... you keep acting like RMS determines how loud a subwoofer will get. For a mainstream reference, an Alpine Type-R is 500 RMS, but it gets just as loud as an Alpine Type-X at 1000 RMS. The difference primarily is the Type-X will blow the Type-R out of the water in terms of sound quality. Pay attention to cone area as well.
