Can I get away with the stock electrical system?

[dbaudio 10+ year member]

So, I have a new car. As if it's not already bad enough that I will be starting to rip it apart this week, I am beginning to think I may need an upgraded electrical system.

Before I jump to conclusions or make an idiotic mistake, can some of you guys lead me to the right path? Ok, here goes:

I want to install the following in my new car:

TC Sounds OEM10

Sundown SAZ1500D

Sundown 100.2 (for Rainbow SLC's)

First off, would 2AWG wire be good for the big 3? Also, could I get away with the stock battery for now? (I can't see why I should spend $150 for an Optima when my car has only been driven for 38 miles so far). Finally, if I do keep the stock electrical system (which I would like to do by all means possible), would a 1 farad capacitor make any difference to my system?

Kinda lost here. Any help would be great. Thanks in advance!

Depends on car and size of alternator and battery itself. Wire it up and see. You should be fine.
