Recently power to the stereo was disturbed at the battery and no amount of messing with the power or the aerial will fix it.

The only time I have known the stereo earth through the aerial is when I have been fitting stereos in mr2's.This is when have plugged the iso loom in and the stereo is in my hand not working, I have then plugged aerial in and it works.
As I have said once fitted it will then earth through the brackets.
The brown wire on the toyota loom is supposed to be earth but my tracing it on the loom shows it goes from the radio plug to the amplifiers not to the body.

Wiring Diagram
One of these seems to simply act as a ground point for the screen on the audio cables, and the other seems to be the signal cable for the rear left channel.But there doesn't seem to be a dedicated wire for grounding the stereo as such, so I guess they must rely on grounding via the chassis when bolted in place.
The amps however do appear to use a brown wire for grounding to a central point, but this doesn't seem to be connected to the stereo, which does seem a bit odd.
