500 is more than enough
You can't use a stock battery, you need a high performance battery.
I ran two amps, two 15s, four splits, two 6x9s off one battery and as far as I know, I have never heard of a two battery set up, unless maybe for competition when your car is off and stationary.

I mean I just had one of these for no reason.

I guess having it consistently drain to under 12volts on a regular basis (monitored from cigarette lighter digital voltmeter) was just unique to my system? Then having alternators fry because of the strain and heat was just I dunno, magnets or magic or something
lol
Alright, I think you answered my question. Essentially the system wasn't being fully powered, wasn't being pushed hard for long periods, and the alternator was under continual strain from consistently trying to charge the battery while running the components, and it was never pushed hard enough to fry the alternators. So basically the problem was never discovered and even if it was readily apparent it wasn't perceived or ignored somehow, someway without mechanical or electrical failure of some sort just by sheer luck
Multi-batteries come into play if the amperage isn't there, as a fail-safe. capacitors are junk and will supply little bursts of power and are essentially useless; they might prevent your lights from dimming a little bit now and then but thats it. A second battery will buy you more time before the system fails at some point. More batteries and you're kind of getting extreme and should just supply more amperage (higher output alternator)
