I'm picking up the infamous engine whine through my audio system. Do I need to reroute my ground or ground the system elsewhere? Any advise?

 

Reground!!!!. Go to the closest possible metal point. Mine's grounded to the floor. The Ground wire is like 14" long. No Whine

 

If that doesn't work, use ground loop isolators. I use em on all my rca's to my amps. They cost about $4 from my wholesaler. But they shouldn't be much more from a car audio store.

I had that whine to for a while. Then I installed better wires, better HU, and grounded to something else and it went away.

Also make sure your RCA wires and speaker wires are a decent length away from any power wires.
