not the extremely powerful ones, but the ones with JBL logo in middle of sub, I THINK they are the pro series, they have 350W rms and 1000W max, how are these because they arent that much for having 1000W max. And if I get two of these, would it work to put them on a JBL 1200.1 amp for 600W x 2 @ 2 OHMs?
