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

positive of one coil to positive of the 2nd coil to the positive of the amp and the same with the negative.......wala 2 ohms per sub

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.

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

Dual 4 ohm means that you have (2) 4 ohm voice coils in the sub.

I just looked at your url link to the subs describtion and notice that they are available only in dual 2 ohm or dual 8 ohm...(this changes everything) you really should find out which version you have and then ask again. I also notice that you have (2) subs check each ones resistance.
