Ughhhh
The media could not be loaded. Powered with a 24 volt 10 amp medical grade power supply it keep shutting off. Thought this was odd so I just tried it with a 16 volt battery pack I had and same thing. I wonder if this is not amperage limited or something. Not too happy. The Dayton audio speaker are only like 20-30 watts each. Sound quality nice but don’t expect too much volume.

Wide voltage range, easiest way to build a bluetooth speaker!
These are really well made little tpa3116d2 class D amps. The inputs are 3.5 with screw terminal speaker output. The power is a negative center round DC from 12v to 24v (note the rated 100w is only at 24v). The Bluetooth module is built in with a pcb antenna on the side of the board. The heatsink is fairly large and the kit includes a pcb case if you're not going to mount this inside a speaker. These are one of the easiest ways to build a Bluetooth speaker, especially a high-powered one driving some real speakers. Highly Recommended!
