Best Answer: nice and easy for you to wrap your brain around.... a dual voice coil sub with 2 2ohm coils you can get your ohms (resistance) down to 1 ohm, or up to 4 ohms. a dual 4 you can get to 2 ohms, or up to 8 ohms. alot is going to depend on what type of amp you are going to power them with.ut i do not know what the difference is between Dual 2 and Dual 4 ohm from single 2ohm or 4ohm. Does it mean that if you wanted to that you could wire a Dual 2 ohm as a 4ohm sub and that you could wire a Dual 4 ohm sub as a 8ohm sub.
