I love to listen to music while taking a shower! But my Bluetooth speaker sucks! So in this video I came up with a new awesome sounding Bluetooth Music System that you can put in your ceiling. It works like a charm, is super loud and sounds amazing. Let me show you how to make this awesome home upgrade! Let's get started! ;-)
