Trying to make sense of pre-wired home theater audio...

Hello,

I just bough a house that has media room pre-wired for home theater audio. I see junction box, near cable connection, that has 5 speaker cables inside. Out of those 5 speaker cables, 4 of them have 2 wires - black and red. The fifth one has 4 wires - black, red, yellow, and green. I also see 4 boxes on the wall - front left, front right, surround left, and surround right, where 4 of those 5 speaker cables come out.

What I am struggling with is what's that 5th cable (black, red, yellow, and green) for. I don't any other socket/junction box (open or closed) where that 5th speaker cable might be connected.

Anybody has any idea?

The 5th cable could be to the center speaker in the surround system. It will have more bass sound to it. Not sure about the wiring, as it could be extras the previous owner had there for another purpose.

Could also be a subwoofer, although that doesn't explain 4 wires.

How about remote speakers...outside or in another room?

That's what I thought first that it could be center speaker. But there is no wall plate for center speaker. Likewise, if it is sub-woofer, then there needs to be a wall plate where that wire comes out.

I checked everywhere in the house and I could not find any junction box or wall plate where that 5th wire would terminate. I also checked cable outlet, just in an off chance that the 5th wire would terminate in the same box.

Only other possibility would be that it might be on the outside wall in back yard. It's to dark outside, but I will check tomorrow.
