I have two Minirig 3 bluetooth boxes and the Sub 2. This 2.1 system is very good sounding and loud. The only drawback for me was, to carry with me, I had to put 3 pieces and the cable in my backpack. And to start listen to music everything has to be arranged.
So, I was thinking about a solution to carry them more comfortable and easier to start the music.
Here is my first try, not very professional, but it works.



I used these parts:
