Hello, I have a 12" Alpine Type-R (the older model) #1241D. It's RMS is at 300W. I have a JL 250/1 amp with the R.I.P.S. technology, so it's very versatile, I know I can work with anything from 1.5-4 Ohms @ around 300W. I want to know: Is there a better 12" sub (1 or 2) that will fir my 250/1? Basically, is there a sub that will take the JL's 300-or-so watts and have better SQL?
