I forgot about the antenna amps - maybe they are indeed connected to  
the "antenna" terminal on the head or they may be tied to the other  
switched output - that turns on the speaker amps.  You would have to  
consult the manual I guess to know for sure.

I am quite familiar with amp circuit as mine went bad. The antenna  
output is simply switched 12v from the radio on-off switch. The amp  
output is time delayed.  Mine went bad a few years ago causing the  
amps to turn off when it got hot.  Obviously, this only happened on  
long trips.  I still have four nails in the car to pop out the head  
unit while driving to cool it off! I believe this circuit has  
something to do with the loud crack you get when turning off the  
radio too.  A nasty habit that mine has started doing again...
