Speaker has damaged RCA terminal.

[Saumya Gupta]

Can someone please tell me a way to fix this?

The white connector on the speaker amp is missing, so the RCA connector just plugs into a plastic hole and the ground does not connect, and music does not carry over to the speakers.
I dont think there is any room to get wire to connect the ground inside the speaker to the male connector.

BNC to RCA will not work in this situation.

Since you have already disassembled the sub why not just get a replacement dual RCA jack assembly. The left and right grounds are common so you can jury rig it to work by just wrapping some bare wire around both output cables so that both grounds are connected together.
