I have been looking around this site for a few days and have noticed that most of the people here think Kicker subs have terrible SQ. However in my system, my 12" Kicker L5 shines and sounds perfect at any listening level I put it at. I have heard many high line subs and would take my L5 over any of them. I have heard the P3's, type r's, xplods, Pioneers, thunder 5500's, audiobahn natural sounds, infinity ref's, and the AA Brahma. The Brahma was the only one that definetly sounded better than mind but that guy had put some serious money into his system. I have also heard the install is the most important part. I can see how this is true. So if there are any that live near Southeast Indiana and you have a Kicker and aren't impressed with its SQ, I highly recomend that you get a box made by Audio Sensations. They did a great job with mine and made my sub the loudest it could be and still sound great.
