If you take a close look at it, that particular RCA set is from a 4 channel RCA so I would figure they didnt need 2 of the channels.i dont understand the wiring //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gifand why are a set of rcas unplugged..
Looks like more than a few minutes. . . .Wow...I am not sure why they couldn't take the extra few minutes and clean up the wiring.
