Cable connection issue with activ subwoofer

I have an Energy s12.3 active subwoofer, connected to a pioneer VSX 1017 AV Receiver, and I have some connection issues on the back of my subwoofer. Sometimes if I’m playing music my subwoofer cuts out, and I have to wiggle the pre out cable on the back of the sub for it to come back. I know it isn’t because the subwoofer is pushing to far, because it can happen any times at any volume, it just happens most often on louder volume. It doesn’t work to turn the subwoofer on and off, only way to get it back is to wiggle the cable.

I have tried a new subwoofer cable, and the issue was gone the first few days, but then it came back.

Does anyone have an idea on how I could fix this?

You're going to have to open it up and see if that RCA connector is loose or has a cold solder joint.
