Ok, the antena is plugged in (has been for that matter) I was not aware of the bracket grounding though. Ill give that a shot next. Ill proably have to rig something up since the stock brackets are gone when the aftermarket HU was put in there (yes i removed the Aftermarket harness and brackets also before anybody asks lol)

I suppose i can just screw something into the deck itself the ground it to the car.
