Your question can't be answered without knowing the impedance of the subs. Are they 1 ohm, 2 ohm, 3 ohm, or 4 ohm coils on those dvc subs? Are you saying your amp IS 2 ohm stable?
well rockford has a simple site to wire up your subs shows you how to configure them go to rockford fosgate woofer wiring wizard. and itll show you what you want to know..
YOU CAN GO THIS THIS SITE IVE USED FOR MANY YEARS PUT IN YOUR INFORMATION OF SUB/ SUBS AND GIVES YOU ALL WIRING POSSIBILITY'S. Rockford Fosgate Woofer WiringWizard SORRY MY CAPS STUCK..HOPE I HELPED.
Check to determine if your sub woofers are DVC 4OHM or DVC 2OHM
SOLUTION 1
If your sub woofers are DVC 4OHM then, from the positive (+) of the amplifier run your cable to the positive terminal of voice coil 1 on sub woofer 1 then continue to connect all the positive voice coils together on both sub woofers.
Do the same for the negative from amplifier to all the negative voice coils of both the sub woofers.
RECAP: all positives together on the positives and all the negatives together on the negatives.
This will give you a 1 OHM load to the amplifier making it deliver all its power but will also run hot. So if you are living in a hot climate take care.
SOLUTION 2:
Connect the negative on voice coil 1 to the positive of voice coil 2 on sub woofer 1
Do the same for subwoofer 2
now you should have a free negative and a free positive on each of the sub woofers. connect the free positives together and follow through to the positive on the amplifier. do the same for the free negatives sending them to the amplifiers negative.
This will give you a 4 OHM load to the amplifier. Not full power in this mode but the most stable working condition for your amplifier.
SOLUTION 3
If your sub woofers are DVC 2 OHM then you only have one reasonable wiring solution.
Connect like solution 2.
This time because of the DVC 2 OHM sub woofers you would have a 2 OHM load to the amplifier. This is also a stable load for the amplifier and does not generate to much heat and still deliver over 50% to 70% of the amplifiers power.
good luck and drop me a line if you still have doubts.

If your sub woofers are DVC 4OHM:
Connecting three together in Parallel/Parallel would make your amplifier run a 0.67OHM load or if connected Series/Parallel then you would have a 2.67OHM load.
If your sub woofers are DVC 2OHM:
Connecting three together in Parallel/Parallel would make your amplifier run a 0.36OHM load or if connected Seies/Parallel then you would have a 1.67OHM load and Series/Series a 12OHM load.
So if your sub woofers are really DVC, it would be impossible that your amp would be playing 4OHM. The numbers just don't add up.
There are amplifiers out there that can deal with 0.50OHM loads but expect them to be on the pricey side, but fairly so, because mostly higher end brands tend to manufacture them and are usually pretty good.
Remove 1 of the sub woofers.
If i knew what the subs where 4 or 2 OHM DVC and what amplifier you are using i would tell you how to connect them for the best possible result.
hope this helps

What you need to check is the impedance that you are connecting at. If you are using for sub woofers... you need to check how you wire them up. If you are using bridge mode then make sure that you have a 4 ohm load. This is possible with a single coil woofer which has an impedance of 4 ohm.
If you have a single dvc woofer, then you would have to either wire it up in stereo with a 4 ohm coil to each channel. If you would like to run it in brifge mode then you would have to invest in a single dual 2 ohm sub woofer and connect it with the coils in series thus obtaining a 4 ohm load.
If you have multiple woofers then it becomes more tricky. You can use a channel amp in bridge mode by getting 2 dual 4 ohm dvc woofers. You would have to connect the woofers themselves in parrallel but to the amplifier, you MUST have the woofers in series with each other. Thus getting a 4 ohm bridged load on the amplifier.
Connecting this amplifier any other way can cause it to overheat and fail.
your probably making your amp run to low ohms if its a 2 channel amp bridged to one channel you can probably only run it at four ohms
Also seeing as your subs are 2ohm dvc you can't wire them individually to 2ohm and use each channel separately. So i'd recommend buying a 2ohm stable monoblock or running it at four ohms. a 1400 watt amp'll still pound at 4ohms and it'll extend your amp's life span
For parallel connections, simply wire posotive to positive and negative to negative. But beware! this lowers the impedence (ohms) by half. In other words if you have 4 ohm woofers, in parallel they would be two ohms. Make sure your amp can handle that. Otherwise connect them in series.
wire what to a dvc woofer?
