I work for a power sport company. We make great products. On  personal water craft, we have  very powerful bluetooth speaker.  They are  also very rugged. I decided to install them on my back patio.

Need to make a 3D printed bracket to hold the controller in place.

I use this black tar to make sure water does not find a way inside the AC/DC converter.

the arrow in the sheet metal is a reminder to install the correct way.
