Wiring DVC subs

Q : How do I wire my DVC subs?

There are two ways to wire multiple voice coils together, series and parallel.

In a series connection on a DVC sub you connect the positive lead from one coil to the negative lead from the other coil, leaving one positive and one negative wire unconnected. To calculate the impedance of a series connection you simply add the impedance of both coils. So, if you have a dual 4 ohm speaker wired in series you would have a 8 ohm total load. 4 + 4 = 8 

In a parallel connection on a DVC sub you wire both positive leads together and both negative leads together. To calculate the impedance of a parallel connection you take the impedance of one coil and divide it by the number of coils. So if you have a dual 4 ohm speaker wired in parallel you would have a 2 ohm total load. 4 / 2 = 2
