    How to wire 2 2-ohm dual-coil subwoofers to create a 2-ohm load?

    So I can either wire each sub’s coils in parallel to create 1 ohm each, then wire the subs in series to create a total of 2 ohm load. OR I can wire each sub’s coils in series to create 4 ohms each, then wire the subs in parallel to create a total of 2 ohm load. Does it matter which way I go with?
