surround sound wiring for subwoofer

[manzanaguy]

I had an addition built and the contractor pre-wired the room for 5.1 sound. He ran wire for the subwoofer (black and red) and used a push type RCA connector for the face plate. Apparently he cut off an RCA pin and soldered the black and red wired to the back of the pin. The wire have since come off. Is there anything I can use better than soldering the wires to the back? Do I run the risk of having polarity problems? What do you recommend?

You should be able to find something here.

If that wire is just speaker cable with RCA connector, that will not do. You will need a coax type cable back there for the sub, unless it is a passive sub only, no built in amp.
You may have a case to have him properly rewire it.
