It shows the ratings on amazon as 4 ohm.

Frequency Response: 23Hz - 400Hz
Impedance: 4 Ohms

ETA: I see now where you said you have 2 of the 1262's. I assumed a DVC would be 2-2ohm coils, and since this is primarily a car subwoofer, you would think it would be 4 ohm.
ETFA: In your OP, it says 1260w so I am just confused.
