Hi,
I've just started making an amplifier for some speakers and I'm completely new to this and couldn't find any information in the documentation explaining it. So I just wanted to know if S-GND and PW-GND can be connected to a common ground back to the negative battery terminal? If not how would I go about connecting the grounds up?

Datasheet: http://www.st.com/web/en/resource/technical/document/datasheet/CD00001048.pdf

Thanks in advance :)
Will


*EDIT* I'm making the standalone version
