A3TDI12

I'm new to the Audi A3 TDI world. Enjoying the initial days.
Except: Not loving the stock stereo system (non-Bose, base Concert system).

I was auditioning some new speakers. I needed to make speaker wire connections, so I snipped the custom Audi speaker wire connector to attach the new speaker.
I need to return the speakers and reinstall the original. (Good news, I only snipped one woofer's wires).

My DILEMMA: I can't figure out how to get the wire ends to release from the speaker custom wire adapter. I can't find any info online or even a photo of the particular speaker connector adapter from my A3.
A picture of mine is attached (from 2012 Audi A3). Also a picture of the receiving end from the 6.5" (165mm) woofer.


How to remove wire leads to re-use connector?

Another approach to connect speaker wires?

Qs:
- How can I remove these wire leads?
- OR where can I get a replacement?
- OR what other option can I pursue to re-connect to the original Concert woofer?

Thanks so much for any help!
