I'm in the process of adapting a tablet to install it permanently in my car. I want to connect the tablet speaker outputs to a separate small stereo amp which will power two small independent speakers solely for the sat nav guidance. The tablet headphone jack is being used for connection to the headunit aux-in for music playback.
Here is my problem; the tablet speaker grounds are separately connected within the tablet, they are not commoned. All of the small amp circuits I have considered have a stereo jack input with commoned L / R grounds. So what would be required to have a common ground input to the external amp whereby the tablet amp will not be damaged?
Thanks.
