the Geolemon article on betteraudio.com is pretty good at explaining what you initially asked. the rest are all pretty useful as well for various tangents about charging systems.
lots of reference material for your argument..

yea i jsut need something in writing to be able to hand over and say.....here! look at this

When the current draw demands it.

There are calculators for this. Its based on supplied amperage and distance traveled. The greater the distance the larger it will need to be...

at what point do you upgrade to say 4 then 1/0 and so on and so on....

Just tell them like this:

Second Battery spiel-

Look your alternator cant properly power this system. If it doesnt already have enough leftover current to run the system and charge one battery how can it charge a second. Yes it will work for awhile with the added second battery but what about when it drains low? Then the alternator will fry due to excessive charging...

Wire-

This is simple electronics. The more amperage the larger diameter needed. The larger the diameter the more current it can handle and the least amount of resistance. These are the facts, this is the truth- there is no other way around it.

basically i got into an argument today with someone who believes that if you add a second batt. you dont need a bigger alternator..what would help this argument is if someone could point out the point at which your audioi system exceeds the limit of the stock alternator. just for s&g lets assume a 100 amp alternator.

I know a few people like this... All you can really do is tell them how to do it the RIGHT way, if they choose not to listen than eff them, let them do it the WRONG way...

yeah my hood was open once and my uncle saw my 2awg wire and notified me that its bigger than the wire going into a house, and how unneccesary it was. He is the type that "knows everything" and is never wrong...so no use trying to explain the difference between DC and AC, resistance, length and gauge, amperes and current, etc.

not an uncle by blood, thank god.

Umm...tell him to take an electronics course and STFU. Larger wire is like a larger pipe for water to flow through. The bigger it is, the easier the water/current will flow. DUH!

yea the other argument is about wire. this guy thinks the world of 8 guage and thinks noone needs any bigger than 4.......not many do but the need exists. he is of the opinion that anything larger than 4 will just add resistance and heat and not be of any benefit to any one regardless of amperage draw.....
