In the mid 80's, when I bought my first car radio/cassette/CD player to use 
in my Cessna 172RG, I bought a Kenwood model that only had preamp outputs.  
This gave me the correct output level and impedance to plug directly into the 
intercom, and, since the unit had no power amps, I was not wasting power in 
audio power circuits that I did not need.  The current drawn by that Kenwood 
approached one ampere when loading a CD, and only drew 400 ma (.4 amperes) at 
all other times.  I had to feed it through a voltage converter since the 
172RG has a 24 volt system.  I bought the Kenwood at Circuit City.
