Need opinions to questions about Big 3, Battery, HO Alternator, Amp Kit, etc.

Right now I have 2 Kicker CompVR 15s on a Kicker ZX1500.1 Amp.. I am currently in the process of redoing my entire system with the exception of the amp. I am leaning towards 2 SoundQubed 15s and I'm getting a custom box built. My next step is my electrical system.

My first question is about the Big 3 upgrade. When I perform the big three upgrade, should I use 0 gauge wire and should I replace the currently wire or run it alongside the current wire.

My next question is about a battery. I want to add an extra battery to the system but I'm not sure what kind of battery I should add. I have heard that the Optima batteries aren't very good and I have also heard that it is good to have two of the same batteries.

Also, if I upgrade my alternator, how many amps should it be.

Lastly, I wanted to know what kind of amp kit I should use. I currently have 4 gauge wire ran. I don't know if its true 4 gauge wire or not. But I have heard that my amp is probably starving for power with the 4 gauge.

Please keep in mind that I am not trying to be in competition, I am looking for a great pounding system in an everyday vehicle. I'm not necessarily on a budget but I'm not trying to spend too much.

Any opinions would be greatly appreciated.. Thanks..

First, yes the big 3 should be in 1/0 same as your amp kit. As far as batteries Sam's club. And last your h/o altanator... here I'd go as big as you can afford. You'll want more at some point and this is expensive to keep replacing ( get a known brand tho. Stinger. Ext.)Do your research.

Yes rip out that 4ga and use 0..dont remove any wire just add 0 for the big 3 and as far as batteries the duracell agms from sams are what i suggest too ..id get 1 for under the hood then a g31 for the rear ..and i wouldnt waste my money on a ho alt at that power ..save the money until u decide to dbl the power

You do not replace any factory wire, you just add to it.

Any particular type of wire or brand of wire that you would suggest for the Big 3 upgrade?

Knu Koncept ofc 1/0 would work great. Or like your other thread someone suggested welding wire can cost you less.
