I don't think my sub has to be wired for a 2 ohm load, it can be run in either 4 ohm or 2 ohm load. Are you suggesting it's best to run it in the 2 ohm load though?you need a 3 channel or a 5 channel amp. You cannot do it with a 4 channel amp with that subwoofer because when you bridge a 4 channel amp, the lowest ohm load it can go is 4 ohms. Your subwoofer being wired to 2 ohms will fry the amp.
