First post! Anyways I'll get to it, I recently installed a new double din raidio. And you guessed it... Have power but no sound. I can't find any solid info on how to get sound. I have AAS with OnStar, however OnStar is not active. Also there is no subwoofer or tweeters either? I've read you can bypass the amp, I'd prefer to keep it wired in if possible. But my question is, what do I need to do to get my speakers to output? Is there an adapter I can buy? Do I need to wire a remote to the amp? I'm kinda stumped here! Thanks for any help!
