don't worry about asking questions, the more the better!! I tested the 12 in a 27hz box and LOVED IT. If you add a second driver and have the room, while keeping great low end, stay in the mid to upper 20's. One MAG will sound fine off of 450 watts or 1500 watts. People are running almost everything in between and love it. As for clarity of 1 over 2 with the same power, I don't think you will be able to hear a difference if the box is made well. If you went with something like a US Amps Merlin MD2 or Sundown Audio 1500D you will feel a decent jump in output over the hifonics. If I remember correctly, adding a second driver of same size with the same power will gain you 3db approx. But application changes from car to car. Two MAGs with 1500 or so watts in a quality box will be very hard to beat for a SQ daily driver with serious output.
