Lots of issues here in one long question. As for the speakers, it could be an amp problem, radio problem, wiring issue, or just blown speakers. The rear HVAC/radio unit will probably need replaced due to it shutting off, and that's a common problem. And as for the ticking sound, since I can't hear it, it's hard to tell you what it is....get it looked at.
