How to wire my subs to get 2 ohms?

HI guys, I have two Pioner Premier TS-W1500SPL  I think They are dual four ohms,  they are DVC, I need to know how to wire them to get 2 ohms.

thank you

YOu know I was told to do it this way Because My subs are Dual 4 ohms and I want to get 2 ohms......

any help>>>>>>

I was told To do it different way, Because Its DUal 4 ohms, you can get either 2 or 8 ohm,

And to get 2 ohms i was told to do it this way,

From one positive of one coil Connect it to the Negative Of the other coil, and the positive from the Other negative from the first coil to the amp same with the other one.

Im confused now, COuld anyone help, ...

thank you

"FATDADYJOE" is correct...connect the positive terminal of one coil to the positive terminal of the second coil then to the positive terminal on the amp.  Negative terminal of one coil to the negative terminal of the second coil then to the negative terminal on the amp.   This is known as wiring in parallel...to determine resistance when wiring in parallel, you multiply the two values, then divide by the sum of the two values.  ex.  4 * 4 = 16...  4 + 4 = 8...16 / 8 = 2 ohms.  If you connect the positive terminal of one coil to the negative terminal of the second coil you will be doubling the total resistance.  Wiring in this fashion is known as wiring in series.  The formula for series is simply add the resistances.  ex.  4 + 4 = 8 ohms.

ok, I will do it that way,,

But them What does it mean to be dual 4 ohms....
