Installing a Clarion head unit and the Metra harness I got doesn't include ground, so where is a good bolt that I can use as a stereo ground? Can I use one of the ones right behind the head unit that you can see when you pull it out? HELP!

 

Yes. It's better to ground it there than using the harness ground anyways.

 

Cool, I actually went ahead and did this last night and it works like a champ.
