Maybe this worked for me because I didn't know it shouldn't...
In my (pos ground) MGA I hooked up a neg ground radio by isolating the radio
from the metal instrument panel with plexi-glass brackets. (Easy to
fabricate by heating and bending/twisting...) Then I connected + to + and -
to -. I didn't do anything special about the antennae because, as I
mentioned, I didn't know I needed to worry about that.
Worked fine for years until I eventually switched the car to neg ground.
