I thought about that too, but that smart 3 will do .5 ohm all day long. I just didn't want the OP to be thinking about too many things at once. That's all. Figure out the electrical upgrade, then make sure them subs are wired correctly. The smart 3 is kind of idiot proof doing 3000 watts .5 ohm-2 ohmI was just curious if he might be wired to ½ ohm.
