How did you tap into the speaker wires? I‘m guessing a plastic connector like a Posi-Tap or Scotchlok? Get rid of those and connect a different way.
This is a good way (I would add two zip ties for stress relief on the one side with the new wire and one ob the other side to make certain the Super 33+ doesn’t peel away. Although, I never use this method since I always cut some strands and it’s time consuming…
I personally like to use butt connectors. Simple, relatively quick, and durable. They make the three way butt connectors, but I opt for the two sided ones. Just make certain you add a bit of the new wire to both sides of the connector.
You can see both wires going into the connector by my thumb (on the photo below). The other side I cut a piece of the new wire, stripped a bit, and added to the connector as a filler so that my crimp will work.
Note the Posi-Tap I removed in the background. I simply used that temporarily to make certain I had the correct wires and fired everything up prior to cutting the factory wires.
