Subs usually allow a bridge where you connect the mono positive to one side positive and the mono negative to the other side negative. Does it not mention this in the instructions? If you don't have the instructions, try it. It can't hurt anything, but use low volume when checking. If you want to verify the bridge before hooking up, use an ohmmeter to look across the positive on one side to the negative on the other. If one combination is open or more than 8 ohms, try the other set of positive and cross-negative. OK?

hey Visha, I was going back over your woofer and looked up the wiring spec. You can actually wire it different ways. If it didn't work the way I told you, here are some other ways: Either connect your one set of wires to one side OR connect the way I mentioned (your one positive to one of the positives on the woofer and your negative to the opposite negative on the woofer).
Then, add a jumper wire between the two extra terminals. What this does is puts the 2 voice coils in series, but it increases the impedence to 8 ohms. A third configuration is to split your wires and connect the positive to both positives and your negative to both negatives. This drops the impedance to 2 ohms and may cause your amp breaker to click off at high volumes, but it will give you the most sound. I have pasted the actual words from the spec below. Have fun with it and let me know if you have any more questions.
The flexible wiring configurations of the Dual Voice Coil (DVC)
subwoofers when used in combination with a low load impedance
compatible amplifier, can give an even bigger and more powerful bass
reproduction capability. DVC subwoofers have 2 voice coils, of 4 ohm
impedance each. Connect the voice coils in parallel for the power of a
2 ohm subwoofer or connect them in series and get an 8 ohm
subwoofer. These in turn allow various installation configurations,
enabling the creation of a truly superior system.
