big 3 upgrade

[Chc777]

I followed the crutchfields method of the big 3 upgrade because it was the simplest way for me I used 4 gauge wire, I went from 1.) alt to +battery, 2)chassis to negative battery 3)engine block to chassis. I just added wires did not disconnect factory wiring.

thats it , but its normally done with 0 gauge not 4

I think he did 4ga since he added and did not remove the factory wires

is that almost the same as taking all wires and running all 0

Only if your factory wiring is 4ga or larger. 0ga usually has a pretty large benefit over 4ga + a stock run

so still run 0 ga with factory if factory is a pain to take out

I choose only 4 gauge wire because my system uses 2x8 gauge wire 0 would be to much and I just put in this system and plan on keeping it for a while. If I was to go any bigger I would use 2 or 0 gauge wire when you do that you would also need to add batteries right. A very expensive project.

one of the main reasons to do a big 3 is to keep from having to upgrade your alternator and/or battery.

wrong, just because you do the big 3 in 0 gauge, doesn't automatically mean you have to get a second battery, it's supposed to reduce having to get a second battery

in adding a battery you don't need to get a huge battery, i run a 35ah battery and it was fine until i added 1200 watts more amps for mids and highs so i got 2 more 35 ah

im running two standard wal mart batteries in series... pushing 1200 watts. i've had no problems at all

4 gauge is sufficient right and no need for extra batteries,

what im saying is, if you ran 0 gauge, you dont need another battery. thats if your running 1500+ watts... depending on the setup

I can always go with 0 gauge when I upgrade to more power consumption amps and subs its not that difficult once you have the know how. I should have just done the 0 gauge first but I wasn't sure. I was to cheap to buy the thicker wire cause I already had 4 gauge. Also I wasn't sure about the flexibility of the 0 gauge. And the ring terminals.
