ok so i made a new thread that got locked i understand what the big 3 upgrade is... i was asking to see pictures of people that have done it to a grand prix. so if you have any pics please feel free to post away
 


have you even searched on here??? theres tons of info on it, not everyone takes pics but its all self explanatory
 
because im a visual person. i understand the big 3 like i said before. i just want to see how people have done it on these cars.
 
Generally speaking...it's not necessary for our vehicles. Do you have maintenance concerns? Want to replace because the wires are old/corroded?

I don't care to get involved with arguments anymore. But there is PLENTY OF THREADS concerning this already. Pictures?...I dunno. But most consider it so simple pictures aren't needed. There's a picture of somebody's spaghetti in this thread...

I'm trying to connect dots....2ohm 15" sub w/Rockford Prime that puts out "1kw" at 2ohms.

Do not need "big 3 upgrade." Also, if you want more output then design a nice box. I don't care to talk about boxes either, sorry. Google pwk designs.
 
Found quite a bit of info using google + grand prix + big three...

Quoting myself from this thread....

If you have a daily driver system Big 3 really doesn't help. Personally, I only recommend Big 3 if you grab an h.o. alt. Otherwise, my system running full tilt probably only uses ~25 amps at most WITH MUSIC. My amps push a total of about 1800 watts using a/b power supplies according to marketing. The op also mentions how he was getting flak from gpf.net. I can't talk for anybody else but I'm contributing the same information everywhere I go. I even have a thread here that explains why big 3 is nothing more than trendy when using stock alternators.

c_k_115: You can upgrade that cable. However, make sure your ground is the same or better.

Some cheap reading about "Big 3"


An opinion about Alt. loads...


First thing anybody should do if they have issues with "dimming" is make certain they have GOOD grounds. Alternators don't have the capacity to fluxuate THAT quickly in order to respond to a "dim". If you have an issue with low output from your alternator that dim isn't for a split second...it lasts until that load is removed. i.e. power windows, rear defroster, etc. Once that "load" is turned off lights will resume normal function.

An example of WHEN to use Big 3.

This makes me smile :)


Bottom line...Big 3 isn't necessary in our vehicles UNLESS you need an H.O. alternator which would be specific to your application of speaker theory. Grounds are most important. That charging wire is only as good as the grounds that are complimenting.

If people come back and say "MY WINDOWS ROLL UP FASTER!!!".....what variables are inherently related to the electric motor working harder? If you can't answer then don't tell me emphatically that the "Big 3" is important. It's a trend outside of specific goals, which most individuals don't adopt.

Sorry...I felt like adding another....

Maybe in theory, but when it comes to hours of work, and money spent on new wire, I would only recommend it if necessary.

You may lower the resistance, but is the resistance already high enough to cause a voltage drop? And is that voltage drop big enough to make an audible difference?

"Big 3" should be changed to "upgrade grounds and don't **** with the alternator to battery cable...unless you've upgraded your alternator"
