is it good/necessary to shut down audio when the rms is low, as the power supplied by the alternator is low? (i have stock bose system) or never need worry this? gonna replace the inoperative HU soon. just worry about any bad driving habbit will do damage.

Don't worry about it. You'll need a stereo about 10x more powerful than that bose system to worry about current draw at idle.

You have enough excess capacity in the electrical system. No need to worry about it.
