wiring 2 dvc subs in series parrlel

wen i wire two dvc subs in series-parrelel which wire do i use wen i go from the positve of one coil to the negative of another coil? do i use the positve wire or the negative wire or both wires?

There is no such thing as "positive" or "negative" wire.  You may use whatever wire works.  Please refer to the "woofer wiring" link in the left hand frame of this site for a wiring guide.Support the12volt.com

the positive and negative are for phase of coil. If two subs are wired the same (in phase) sound will be how it should be(if box volume is correct). If wired wrong (out of phase) sound will be nullified by cancellation. To wire dvc series parallel will be the + side of one coil to the - side of the other then same on other woofer. Then hook up both + sides and both - sides to a single channel and you have the correct wiring for that set up. The calculation would be as follows: coil #1 ohms + coil #2 ohms = X X/2= Ohms for that circuit just remember series adds and parallel halves
