That sounds like a fun project! I actually like the idea of building your own boom box because you can make it just how you want it. You could start with a sturdy wooden or plastic case, add a couple of good Bluetooth speakers, and maybe a small amp board with a rechargeable battery. Some people even use old toolboxes or vintage suitcases for the body, which looks really cool and portable. It’s a nice weekend project, and the kids might even want to help out too!
