Please choose either D2 or D4 before checkout. D2 means dual 2 ohm voice coils. D4 means dual 4 ohm voice coils. The right choice depends on your amplifier, the number of subwoofers you are using, and your target final ohm load.\u003c\/p\u003e\n\n\u003cp\u003eFor a single subwoofer setup, a dual 2 ohm subwoofer is commonly used when the goal is a 1 ohm final load. A dual 4 ohm subwoofer is commonly used when the goal is a 2 ohm final load. Always verify your amplifier’s minimum stable impedance before wiring the subwoofer.
