Ok, let's get down to the nitty gritty. What does all this do for you? You can use a combination of series and parallel wiring to create a certain load to present to an amplifier. If the amplifier is well designed, the lower the resistance of the load, the more power it can make, because you can draw more current form the amp.

Back to our collection of JL Audio 12W6v2 woofers. We know we need a 4 Ohm load to make our Audison amplifier jam. But we have six 6 Ohm voice coils. What to do? Simple, connect the voice coils of each individual driver in series, to create a 12 Ohm load. (6 + 6 = 12). Now, here's what's so cool about our W6 series woofers. If we connect the 3 drivers in parallel, we get the following:

R = 1 / ( (1/12) + (1/12) + (1/12) )

R = 1 / (3/12)

R = 1 / (1/4)

R = 4

You got it! We made a single 4 Ohm load. And that sucker will JAM! How much power does each sub get? Well, the easiest way to figure it out for this example, is divide the total power equally amongst the subs. Let's assume for fun the Butler 750 makes 300 watts bridged. Each woofer will get 100 watts, well below their rated 300 watts each.
