I want to make the cable removable and attached in one side only, so I'm thinking of using mini-stereo/TRS plug. But if like you said, use 1 core for each channel and join them only in the other side, then is it better for me to use TRRS plug for the one near the speaker and the other on is using standard mini-stereo plug?
or, I can use 2 mono plug connected in single side, but I don't know how to split the cable neatly (Y split).
thanks
