Reuse Bose wire connector (prewired on the wall) to connect to Polk speakers

I recently bought the Polk TL1600. Previous owner of my home has prewired the Bose proprietery wires on the wall and has a 4 socket female connect on the speaker side. How do I re-use the wire and connect to the Polk speakers?

Would appreciate any help since the Polk system that I bought is just sitting in the box for the last 2 week due to this issue.
