I understand the whole 2 ohm and 4 ohm rating, but I do not understand the watt rating for DVC subwoofers. If a DVC subwoofer is rated at 600 watts, does that mean that each coil is 300 watts? I am looking at the Kicker CVX10 which comes in both 2 ohm DVC and 4 ohm DVC and is rated at 600 watts. Thanks.
