I got these two box designs off Ca.com, im just wondering if they will be fine. Will be powered off a nine.1 1200w@1ohm with the gains turned down a little bit. Running a 15 rlp http://img30.imageshack.us/my.php?image=35...z465sqin0cb.png This one is 3.5 cubes tuned to 30hz http://img30.imageshack.us/my.php?image=32...z435sqin9pz.png This one is 3.2 cubes tuned to 28hz. Im leaning more towards the 3.2 cubes as I want to have SOME space left in my trunk. Would these two box designs be sufficient or should I go with tomsething else.
