Speaker whine, correlate to engine RPM. Where do I find all ground connections?
Hi guys, besides my LPG/Gasoline fuel trim issues, I have another one that I have since I bought the car roughly 1,5 years ago, and it's slowly getting on my nerves.
The speakers always give off this whine, one day it's less, another day it's really annoying. I read that this is because of bad ground connection, and my question is where all the ground connections exactly are. Where do I need to look? It also tends to be a specific speaker in the left door (tweeter), and in the middle on the dashboard. I haven't tried the other ones. People comment it sounds like a turbo, you get the idea...
So, where do I found all the ground connections, so I can check and clean them? What else should I look out for?
