ok guys, this time I got an active speaker for the GMC type bluetooth with symptoms when it's turned on, the indicator light is flashing, accompanied by a pause, like a low voltage, after disassembling and measuring the VCC voltage on the secondary it pulses up down to the rhythm of the pause on the speakers.. ok to find out more about the cause of this GMC speaker damage, please watch the video until the end, especially for beginners so that they can understand & don't fail to understand, ok thank you🙏🙏🙏 #sepekergmcrusakpsu #speceraktifgmcrusak #spekergmcblututrusakpsu #sepekergmccuman indicatorlights blinking#caraservisspekergmcturn off
