Yes, you can get both kits of two and single + connectors from Summit too. I
have a dual connector kit unused that I bought a while back but never
installed. You basically drill an oversize hole and mount the stud with
plastic washers/spacers.

The audi unit is mounted on a flat surface with just a pair of sheet
metal screws. It is just the + connector. The ground is through a bolt
spot welded to the body.
