Need Help finding Grounding Location for Head Unit
Just installed an Alpine ILX-W650 with a PAC harness and everything is working EXCEPT, I'm getting some low volume noise and alternator whining. I need to find a better grounding location as the one attaxhed to the factory harness is not enough.
I found this diagram of the grounding location #3, supposed to be near or behind the driver's seat. I can't seem to locate it! Before I continue tearing apart my car to find the location, can anyone give me advice? I have a 2010 Grand Sport Coupe.
Here is the diagram I'm referring to and the picture I have of a previous location located near where the seat belt connects to the body. C6 Diagram After removing panel near seat belt
Please help as I'm dying to get back on the road again !
If it's anything like the passenger side, it's further down closer to the base of the pillar, not the top. You have to pull off that plastic piece attached by your seat belt.
There is also a good grounding point near the fuse box you can use. It's not a factory ground, but it's a bolt connected to metal that is grounded.
