At idle your alternator isn't putting out it's full charge. The 120 amps is at or above 2200 RPM. At idle your pretty much just on the battery. (That's the way the car is designed)
There's probably nothing wrong with the alternator if your car battery is staying charged and the car starts without problems.
You could turn down the stereo when you're at idle and probably not have any problems...
The "Big Three" article is interesting - putting 1 gauge wire will certainly assure the most power reaches the components but if you haven't replaced an alternator before, don't do this - if you don't get it right you'll burn your car down.
