In a Dual Voice Coil Sub you have 2 red and two back going into 1 red and 1 black, which is the connection on the box the sub is in.

just to make sure...both red go to single red, both black on sub go to single connection black

or is it some funky strange way that will work but confuse me.

 

The way i think you have it wired there is in paralell which will give you a 2ohm load at the sub. The other way to go is take the to wire it in series. Basically if i can explain this without confusing you is you run the red (+) wire to one side of the sub then from that same side take a wire from the black(-) and take it to the (+) on the other side of connections. Then run the remaining (-) lead back to the negatice lead on the box



box + <--------(+) (-)------
I
I
box - <---------(-)(+)------



Sorry for the bad drawing it was the best i could come up with but you get the idea(i hope)

 

If you're wiring it in parralel than yes you wire + to +, - to -. Never with DVC subs in stereo, make sure it is mono or bridged. Make sure your amp can handle the impendence you wire it as. If it's a dual 4 ohm sub than your impendence will be 2 ohms. Make sure your amp says that it is stable with a 2 ohm mono load...unless you like buying new amps.
