Infinitely Baffled wiring

When you build your own sub, there's a lot to it. Phase delays, sound pressure levels, cabinet volume and construction are just the start of it. When you get into multiple drivers, it gets even more complicated.

In my case, I'm trying to figure out how to wire my speakers. I have two of them. But.. each of them have two voice coils each of which is 8Ohms. I can wire them in series, which would make them 16 total. I can wire them in parallel, which makes them 4. But- I have two speakers to wire, so the choices continue- I can make them parallel or series too- so depending on how I wired the voice coils, that could make them as low as 2 Ohms, or as high as 32.

Throw into the mix that my amp has three modes- stereo (two inputs, two outputs), parallel (one input, two outputs), or mono (one input, one output) and can delivery scary amounts of current, I need to make sure it is done right.

And finally, I may add two more drivers later which add into the conundrum. I've been consulting with two of my friends whom I consider experts, and they've given two different answers as to how to meet my needs.

The good news is that my amp is flexible enough to drive 8 down to 2 ohms, so I have a lot of choices.

Mr. Stocks sent me this diagram, which is the way I'm headed. I only want to climb into the attic once more to wire it (kind of unpleasant to be up there with a soldering iron).
