electrical chart

[jay_dallas_bass]

So while browsing and researching through google and smd I noticed two things.

1. The recommendations of high output Alts and extra batteries

2. No easily reachable chart giving a general rule of thumb of what to upgrade to.

Y'all understand what I'm trying to convey? something like wattage * total fuse rating of amp(s) for X alt battery combination.

If someone has something like that it would be great if not would someone be willing to assist me in creating one for future reference?

There is no rule of thumb for something like this as far as i know. Its mainly like, get the biggest alt you can find because you don't have much of a choice over stock.

Here is a link about alternators

And a link about batteries

If someone would make that kind of chart is should be huge.

i mean really really huge, because you can have multiple combo's for batt/alt for 1 setup.

I so posted those videos up in the other alternator battery post lmao.

Boon's chart:

4kw = 1 battery

7kw = 2 batteries

10kw = 3 batteries

Done.

If you're running more than 10kw, wtf are you doing asking the internet about electrical upgrades.

Same goes for 7kw, and probably 4kw. And if you need to ask the internet, your system probably isn't big enough to need them

I don't agree have done tons of cars were a single t600.6 at 2 ohm or t15001bdcp will kill a car with just one battery. Also just had a car today with a t25001bdcp and t1004 with three batteries and the subs kept cutting out because there wasn't enough power. i would definitely say you total amp rating is the only way to rate your electrical. I mean waht if had three red tops at 50 aH a piece or I had kinetik 2400 that's 120ah by itself????

Not my problem if cars you wire up shit themselves all the time. Maybe you should take a long hard look at how you're installing them.

I've run a 10kw+ system off a grand total of 3 batteries and a stock 90A alt. Total Ah rating was ~300.

I know what you mean. At king of socal, Apline was running a Stetsom 7k at 1ohm, off a stock alt and a KHC1800 and 2400. And was demoing a lot, plus burping, and bassracing.

Still disagree with you statements are way too general most times issues can be traced to a puny 10 gauge ground from chassis to battery there are just too many variables to say hey two batteries will always do this three will always do this also when I say kill I mean the lights are dimming like crazy car is seeing anywhere from 10 to 11.5 volts
