When I bought my house I had the pre-wiring done for a home theater set-up. It looks to me like the wiring that they ran for the speakers is one (or two) continuous piece(s).

Where the wire is pulled thru the wall, it's an unbroken loop, not the + and - ends like I am used to.

I'm guessing this is the standard way of doing the wiring, so how do I hook up my speakers? Does it have something to do with hooking them up in parallel? I'm new to this, so any and all help would be appreciated.

Thanks in advance.
