Hello, I've got a question. I installed an OS3-Bose into a 2008 Impala, and later installed a 4-channel amplifier, and now the Onstar doesn't work. Well...it works, but it can't be heard. I assume that I can just install a single speaker for the onstar under the dash somewhere, but do I just connect that to the OS3-Bose harness? Thanks!

The OnStar® volume is controlled from the adjustment screw on the interface. Make sure this is set to the desired level before
mounting the interface and reassembling the dash.

when you added the amp you eliminated the onstar audio as it normally comes out of the left front speaker.

I understand that I eliminated the audio...now I want to get it back. Does anybody know of a way to do this without adding an external speaker?
