Re: Speakers make loud screeching/whining noise, only when car is running?
Retrace the speaker wires all the way from the amp to the speakers and see if there is any pinch in the wire that could be grounding on metal. You could also try a new set of rca's, just to rule them out. Just run them from the Hu to the amp over everything (without tucking them under).Troubleshooting really ***** sometimes.
