I would have to say a properly done "cut through" on a single cab truck is awesome....However if you are gonna do a cut trhough why only 1 sub? Of course one will still wang hard. However i dont know about only a 12" X 6" hole in cab? Fosgate, did you hit 151 with that box listed in your sig tuned to 28hz? Not doubting you but if so that is a pretty wicked score....
