Wrong, completely wrong. You need to read up on ohm loads, how to properly wire subwoofers and learn how to set gains properly before you blow a perfectly good sub. THERE IS NO 1 ohm load possible with a D1 sub. If you wanted a 1 ohm load you have to buy a D2 sub.
here's the wiring diagram for all possible wiring for a 1 ohm dual voice coil subwoofer.
