I know this has been beat to death, BUT.......I currently have one kicker cr15 in my car 2 ohms 1100 watts...Hits great,,,What would I lose by going to 2 kicker cr12's at 2200 watts??? Or would I gain spl???? I dont have the room in the trunk really for the box, amps wiring, etc....Dont want to argue brands, or watts, just some kinda idea what to expect....Am going to put the 15 in my garage in place of the 2 12 fosgates I had in there.....Thanks for any ideas on this....Tom
