So I have decided to just completely drop the JBL line sub wise. I am debating on going to the Memphis Pr 12's. Are they really what they are cut out to be. My buddy has 2 hooked up to the 500 watt PR amp and they are loud. I have a JBL GTO1201.1II. For $77 a piece could I really go wrong with getting 2 of them or is there something better for the same price from either kicker, alpine, fosgate, or boston?
