Dayton Audio KABM 215 and 30M: cheap but disappointing Bluetooth amplifier boards

This is my video review of the Dayton Audio KABM 215 and 30M -- two very affordable Bluetooth amplifier boards from Dayton Audio.
✅ PROS: Cheap, good sound, DSP/equalizer support, DIY Friendly
⚠️ CONS: Get hot, weird volume control, high idle power use, not as powerful as they say
