Pierce Barrett Posted July 23, 2012 Report Share Posted July 23, 2012 Alright guys I have another question that's gonna make me look like a car audio noob. My Dad likes me to explain everything I do to my system and the reason why I'm doing it. I was explaining the Big 3 and he wants to know why you run a power wire from the positive of the battery to the alternator. I couldn't even answer it. If you could tell me why please do.

IdleSilence2580 Posted July 23, 2012 Report Share Posted July 23, 2012 So that the alternator can charge the battery. That's the simplest answer.

jeep0312 Posted July 23, 2012 Report Share Posted July 23, 2012 Because the battery gets its power from the alt...

Crandis16 Posted July 23, 2012 Report Share Posted July 23, 2012 i would explain it more as running the positive on the alt to the battery.... that way the battery gets power DIRECTLY from the alt as opposed to going through anything else.... plus thicker wire = more current = Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...

That's why I did it anyway Quote My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...

That's why I did it anyway I'm about to install a volt meter so I can watch I voltage but I see a lot of people running 14 volts is that necessarily good?

MrSkippyJ Posted July 23, 2012 Report Share Posted July 23, 2012 14.4 volts is what a 12 volt system charges at.

You want to start getting worried when it's dropping below 12v. Amps like to operate at higher voltages, if you drop down too low then your amp will go into protect which is bad.
