Speaker Cable for ADP-390

[JWhite]

I am setting up my theater room and would like to know what the best gauge would be for my rear speakers. From the title, they are ADP 390, and they will be approx. 20 feet from the amp and TV, so I am figuring 12 AWG would be good. Does this sound right?

With a 20 foot run you could probably use 14 gauge but 12 will work just fine.

12 is over kill, not that it won't work, but its not necessary....

Go to this site and scroll down to the chart... Your speakers will run under an 8 ohm load, cranking it up really loud may head into the 6 ohm area... but I doubt it...
14 ga wire will work just fine... which is still over kill for that short run...
