What type of cables do I need to hook up subwoofer?

Returning to the Y-adapter issue, the signals reconnect inside the sub, right? I have a feeling most people (including myself previously) have used the Y-adapter because they figured, "might as well be sure the whole signal goes through!" But electronically, it doesn't make sense, right? Since we're talking a single output from the AVR and voltage is all that matters, isn't the Y-adapter superfluous?
Isn't this just making a signal path that looks like:

Oops, that did NOT come out looking right. But you get the idea. (I'm not trying to be know-it-all, promise. I'm legitimately asking because I only thought about it recently and I realized I don't know for sure.)
If you use a y adapter it does increase the input signal by 3db. (or is it 6 db?) Either way - it increases the signal that goes into your amp. If you are not running your amp full bore and running out of power - there is not alot of use to the y adapter (unless you want to use it to hook up more than 1 sub). If you are hitting the limits of your amp, it may give you a little bit of a boost in bass.
