High(er) Wattage System Electrical

[MastaFlyMason 10+ year member]

I'm doing a bigger system in my new car (03 Mitsu Galant) and I am wondering what I should do for my electrical. I believe my stock alternator is 90 amps. My battery just died so I am wondering what kind I should get so it's kind of urgent as I need my car. As of right now I am running 4x DD 1010 subwoofers on a Concept 1000rms amplifier off of 0 gauge Audiopipe wiring. No big 3. I plan on soon getting a bigger amplifier (probably an AP1500) and also a 4ch amp for my mids and highs that will be around 4-500 watts, so I'm looking at around 2k watts total. What should I do for electrical? I was hoping I wouldn't have to get a new alt and just put a bigger battery up front, a secondary battery in the back and do the big 3 and i'd be okay but i'd like some opinions before I start dropping money. Also, if possible i'd like the up front battery to be something I can get locally but I can order it if it is necessary.

Thanks

Well that's really not that much more and depending on your ohm load depends on how much reinforcing will be needed but minimum is the big three and a decent battery like a yellow top or similar.

Subs are running @4Ohms right now, but with the AP1500 it will be around 1. They are 1Ohm SVC each. What is a yellow top?
