OK, so I've finally found some free time to get the sub hooked up. We removed the screen and I began removing the old sub and worked to get the new sub connected. BUT, I found one fatal flaw in my building logic...the input connectors! When I built the sub, I used speaker connectors. Now, there's nothing wrong with this, but I didn't think about how I was going to connect the wiring. I ran two runs of RG-6 quad shield to the front wall when I built the room. The RG-6 is much more resistant to interference, so I thought I was good to go. The old sub had an "F" connector input, so all was good. The inputs on the sub are speaker wire inputs.

I spent a bit of time at Radio Shack this afternoon trying to figure out how to make this conversion. I don't think that I have a good solution, so let me open it up...how do you convert between RG-6 and speaker wire inputs? I could run new speaker wire to the sub, but I'd like to avoid that if there's another solution.
....sigh. Why does this have to be so hard?
