when i have the sub wired (supposedly parallel), i measure the ending wires (the final two that would go into the amplifier) and my dmm reads at 1.9-2.0 ohms (jumps very minimally.you dont need to get a clamp. just measure each side. if each side says 2 ohm its a d2 sub. means ur either at 4 or 1.
i stole it from some guy on another forum //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gifWhat's up ignoreme. Cool pic.
