I retrieved this amplifier board from an Ion Plunge bluetooth speaker. I have no idea where I would connect the ground and power(vcc?). I am not that electronically minded when it comes to figuring out where to connect what. I do know that a the usb micro cable connected to this to charge the batteries. i have tried looking for help but haven't the slightest clue what to look for or where to look. Any help would be greatly appreciated.
