So for now I've got a couple Infinity subs sealed on a kicker SX1250.1 at 2 ohms (about 350 watts to each sub). I'm looking to go to something like the 12" Fi Q and drop my amp to 1 ohm (which would put the amp to 1400w off the birthsheet)in a ported box.
As a general rule would I be gaining or losing spl off this?
