After some craigslist hustlin, I wound up with a JL 12w7. I got quite a deal on it, but its not at all what i had hoped for giving JL's overrated rep. It's a decent sub, but can only take 1000w rms and it doesnt really like that. I hear the motor on the w7s are really good though, so im thinking of a recone to 15" using the w7s motor. Is this a good idea?? Does it sound like a good or bad idea?
