Debating on to either buy 2 12 Sony xplods in ported box or 2 12 Rockford R2. I have a Rockford prime R500 amplifier. ( hook my amp up to 2 12 xplods and sound nice. Push the 12 pretty good. My question is r the prime R2 better than Sony in SPL (bass wise) I don't care about any other subwoofer. If u can't answer my q then don't waste my or ur time and don't answer the q
