Stereo & Electronics - Pass. Side speakers won't work

None of my passenger side speakers in my 98 Z28 will work. I haven't tried anything other than making sure they are still plugged up. I kinda thought they might have been blown but what's the chances of just the ones on that side to blow? I'm thinking a loose connection or ground somewhere. I just have no idea where to start looking. Anyone had this happen before? It still has the factory cd player and speakers also.

Test it by unplugging one of the passenger side speakers and swapping it with the drivers side. Best way to do it would be with the hatch speakers, they're easy to uninstall. I would start there...

same prob here. in for answers

bump.
