I always thought it was not a good idea to ground to the battery? I am grounded to a factory grounding stud just north of the battery. At least I think it's a factory ground because there was already a thick black ground cable connected to it and it's not painted. It's located below the spare tire (which I removed).

I will take pictures of it all tomorrow and post them, if anything maybe this could turn into a good thread for the archives. I will try to get as many detailed shots of the wiring as I can.

I spoke a little bit with El_dude on another forum and he suggested trying to move my SVEN 4 converter to a different location, if that doesn't work I will look into changing the grounding locations of the amps or cutting the factory grounding cable of the head unit and running it to a different location.
