Opinions on wiring upgrades

[....... 10+ year member]

I just recently looked into upgrading all the electrical components in my car. Currently I have a stock 160 amp alternator with the big 3 done in 1/0 gauge. Say I wanted to run something like a Sundown SAZ 3000D off of that. For the time I was told I can set my gains to desired voltage, so between 1.5-2k until I upgrade my electrical. The first thing I want to do is upgrade to a better battery.

When I do upgrade my battery, I want to buy one monster battery to take care of everything. My current OEM battery is in the trunk as I type. Is this a possible idea, or would 2 good batteries be better for my setup?

Second. I've done some research, along with using that search bar up there quite a bit but I still have some questions. I'm pretty sure I'll be going with either a Mechman or DC Alternator for my car. They both have a 270 amp one, but DC says theirs does 270 at 1200 RPM while Mechman does 270 at 1800. Are there any other companies out there yall would recommend other than these two?

I've seen some people that run 3k+ systems without upgrading their electrical. I've also heard 2387365 reasons as to why this is fine, and also 29385670 reasons why I shouldn't do it. Does anyone have anything to say about this?

Get a 2nd battery, like a Batcap 4k, that'll take care of you.

More power, cooler your amps run, that for sure. I guess the higher the voltage (or less voltage drop), the cooler your amps stay (to a degree). I have 3 batcap 2ks and 1 3k upfront for about 2000w right now.
