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.

No. The RCA ends would have to be cut too. How close is the receiver to the RCA jacks?
Unless there is a lot of slack hiding in the walls it probably won't pull all the way to where you need it. Might be easier to just buy some in wall wiring and do a new run.
