I have 14/2 in-wall speaker wire for my sub.  The problem is, I have 5 way binding posts for connections at both locations (behind receiver and behind sub).  I have a single subwoofer RCA out on the receiver.

I understand the best solution would be to use one of those costly subwoofer monster cables direct, but that isn't an option.

How do I connect this up?  Does your standard subwoofer cable with an RCA plug on it actually have 2 wires in it?  If so, do I just cut a 12" subwoofer cable with RCA ends in half, try to separate the 2 wire components, and then wire one to the + post and one to the - post on each wall plate?

I am new to all of this, so sorry if this is a dumb question.  Kind of wish I would have wired the walls with a subwoofer cable before it was drywallled off and closed up...

Yes it will work, one wire is connected to the center pin and the other is connected to the outer rim. The outer rim is the signals ground and is not connected to a wire but a metal braid outer jacket. Most rca interconnects can unscrew so you can see the actual solder connections. The only problem could come from interference from power wire behind the wall because speaker wire is not shielded. A subwoofer cable is just a single rca audio cable. Sorry for not having any paragraphs, didn’t want to switch to IE.
