It's due to voltage drop

@ idle without music mine also bounces up and down, if u turn the wheel all the way one way it will drop down and go back up, and when the a/c or somthin cuts on it, it like goes up then back down and you can hear the engine rev up a little, just get a DMM and test the voltage at your amp

Yep alt is kicking in. Just keep it above 12.4v and it should not kill your electrical system.

Thats because your compressor from the AC, and the power steering pump are kicking in taking voltage from the system.

Finish the Big 3. That may help a bit.
