I was looking at a couple different double dual voice coil sonosubs I might build and was wondering how the wiring would be accomplished if you had a 2 separate external binding posts which ran to parallel wiring of the separate drivers. How would you power both of the drivers in a 4-ohm load with an amplifier if you had the dual binding posts? Would you have to split the positive and negative fields of the sub amplifier once again to be distributed to both binding posts? And if this was the case, wouldn't this yield a 2-ohm load from the drivers? How could you power these dual drivers with a 4-ohm load from each driver with a single amp?
