what is the difference between a 2ohm and 4 ohm sub?

The difference is the resistance to the amplifier. If a subwoofer is 4 ohms on the amp, then it gets less wattage. Usually with 4 ohm to 2 ohm difference is that the ampflifier can put out twice as much power to the subwoofer because it's half the resistance. Dual 4 or dual 2 can only be hooked up to 2 or 1 ohms to an ampflifier unless you go up to 8 or 4 ohms on a subwoofer. More heat is generated, so be sure with a 2 or 1 ohm sub, you have a cooling fan built in the amplifier. And whatever you're hooking up, make sure the amp can handle it, with true wattage ratings and stability.
 
4ohms subs have better sound to it, has more viariety of sound waves, but the 2 ohms subs can give you more pounding and just raw bass poundage doesnt give you the varitey of sound waves.
