Your head unit is picking up feedback from your ingnition system. Check your points and maybe some new insulated wires.

why would that matter only when the front speakers are hooked up? have you experienced this before?

I have not personally but a friend of mine has a 87 monte SS and that was his problem. As far as the issue with the speakers being hooked up im not sure

Check your grounds. If you're getting feedback or crackling, it would be that.
