My factory head unit is not coming on. It appears to be dead. Now I removed the door speakers and the footwell sub thingie, but I don't think that would keep the head unit from powering up, would it? I don't have the funds to replace the head unit just yet. Any suggestions on what might be the issue? I am currently in the process of replacing the door speakers and the sub with aftermarket amps... So I just need to figure out this whole factory stereo head unit issue.
