I want my stereo wired so that I can play it without the key--it's
a Westy.  I put in a new Panasonic a few years ago and found that
it draws almost its maximum rated if it is OFF and the face plate
in left on.  It is running who know what in the display.  Pull
off the faceplate and consumption drops to almost nothing.

Sort of screwed my idea of using the remote from bed to turn it off.
Overnight it will draw something like 12-15 amps, so I crawl out
of bed to remove the faceplate.

It was clearly designed to NOT be wired the way I did.
