Many things come into play in this subject. Like when I ran my old Xtant 3300x, I had no issues with current because that amp is a tank with lots of on-board capacitance. I never should have sold it.
When do you do most of your listening? Key on or, key off? That makes a diffidence between using a big Alt or extra batteries.
Caps can work of course but, IMO that is because of small on-board capacitance, too much wiring resistance, insufficient ground and the like.
