The following file outline detail information regarding Dual Voice Coil Wiring. There are two basic means of connecting a DVC driver: parallel and series. Parallel wiring means a dual voice coil subwoofer has a 4-ohm coil subwoofer. The coils are wired parallel to each other giving only a 2-ohm load to your amplifier. The lighter the load, the less likely it is to burn out and the more it is able to put out. When parallel connecting a driver, this means connecting both voice coils to the amp in the same way, all plus terminals connect, all minus terminals connect. The other method of connecting DVC drivers is to wire the voice coils in series. This means connecting from the amp to the input of one voice coil, from the output of that voice coil to the input of the other voice coil, then from the output of the second voice coil back to the amp. The series connections lets you program multiple woofers to one amplifier but without overexerting the amplifier. This is a wiring option you can choose if you are really trying to bang out.
