second battery

would running a second battery give me 14 volts just as consistently as doing the BIG 3?

not necessarily

Adding a second battery would not make the cables carrying the current more effective...

SO WHAT'S THE PURPOSE OF THE SECOND BATTERY? I MIGHT RUN TWO AMPS, AND I JUST NEED TO KNOW.

Unless you ran it parallel for 24 volts, or is it series, i get those confused a lot. Then you could drop it through a genius scheme of changing to ac,using step down transformer,and changing back to dc...for 14 volts. However, you'd still need to upgrade electrical wiring as well.

do you mean running 2 sub amps in addition to the highs and mids amp

NOPE, GONNA BRIDGE MY MTX 5400X(TRYING TO RUN IT AT 14 VOLTS TO GET 200X2 AND 300X1) AND A PROFILE 4 CHANNEL FOR THE MIDS/HIGHS

The purpose of the second battery could be for many reasons, but mostly to help out your main battery from overstraining itself and it makes a good distro block for a lot of wires.

With My Setup, Will I Be Ok With Just The Big Three? It's Imperative That I Remain At 14 Volts.

well take a look at my sig i upgrade to the 2/0 wires a bigger alt and the big three and i know i still dont get a constant 14 but i havent put a meter to it yet but im sure cause i still get alight dimming at .5 ohm but that should be normal for that application

So overall you're looking at around a 1k watts? If 360watts pulls 33.6 or whatever amps, then 1000 would be somewhere like at least 95 or so, so what kind of stock alternator do you have?

MAN, I WON'T BE ANYWHERE NEAR .5 OHMS.

If you Always need 14 volts, then a new or extra alternator would be all i can think of...

HAVE NO IDEA ABOUT THAT STOCK ALT, GUESS I SHOULD LOOK IT UP.
