Is the 70AMP alternator too small?

Is it possible that the alternator could ever keep up to having all the accessories on? With the rear window defrost, headlights, heated seats, and climate control, I am drawing about 56 amps. Is that a lower output than it should be? That is when my battery voltage drops to about 11.8volts at idle. Is this normal? When I rev the engine a little it comes back and with everything off, it is around 14volts.
