This kind of question gets asked weekly. Generally with a little more information like, how long are the runs, what is the impedence of the speakers being used, and what kind of amplification is being used.

But anyway, once again..... here is a helpful tool: http://www.roger-russell.com/wire/wire.htm#wiretable

You need to get the appropriate gauge for your application, which in this case basically relates to length. That being said, I usually just say 12 gauge because it's cheap and you can run that anywhere long or short no problem in any system. So what post #2 said.

Although your runs don't significantly vary, I would keep the front three speakers at identical length (10 ft.) and the surround speakers again at identical length (33 ft.).

In that case, I would run 14AWG minimum, although 12AWG for safe measure really isn't that much more expensive.

Okay i'm going to order 100 feet 12awg wires at monoprice.com. Any more tips?

People here won't tell you this much but 16 gauge is sufficient for most runs, If you actually do the math on it, you really aren't loosing much power. With an 8ohm load, running 100feet, you get 83% of your power to your speaker with 16gauge. With your longest run, 16awg will get 94% of your watts to the speaker, with 12gauge, you get 97%, the difference is 0.17dB, pretty moot by anyones standards.

However, with monoprice's situation, I see no reason to regret going with the bigger wire, you spend a few dollars more. I find it very funny when people begin to get excited about how running 10guage wire makes their speakers noticeably louder for their 6' run when they were using 14 before.

The problem is speakers give the average rated impedance like 8-ohms; but if you look at the full frequency spectrum range and impedance, speakers will range from 2-ohm to 20-ohm depending on the frequency it's driving. It's the low dips in impedance that's going to take the greatest losses. So going with 12 Gauge is the best performance for the buck, IMHO.
