Answer
Bronson:
 Not actually a SAAB specific question , but one I can respond to anyway....
 My guess is that the ignition switch's accessory terminal is intermittent. So what I would do is connect both the main power (Red) to the memory retention wire (usually yellow) together, disconnecting the red wire from its original spot. Thus, both red and yellow wires are connected to wire was originally connect to a power source controlled by the ignition switch which would turn the radio off when the switch was off. With the arrangement suggested above, the radio will be on all the time, controlled only by its off-on switch. That is the "price" of my suggestion, the simplest one  I can think of.

 If that is inconvenient for you, then you'll need to change out the ignition switch or repair its associated wiring, a MUCH MORE complicated solution.
