320 amps is probably the most common amperage. 10K pulls between 900 and 1200 amps depending on its configuration. That's 3-4 times the alts rated capacity, ... unless you have duals on your 10k of power, then it’s still double the alts capacity
Alternator goes out, drops two tenths of a volt under load, gets a little hot, takes out a rectifier or regulator and everyone loses their mind. They make a post at the next red-light, post pictures, get all upset, send their alt to someone else to repair thinking they will do a better job and talk about it for the next 18 months

Subs ran at double their rated power, but it seems nobody cares when they blow, they buy "so and so" soft parts.
Amps ran at double their rated specifications; nobody cares when they blow up. They care more than subs, but still, they call an Amp-medic or whomever and get it fixed with very minimal complaining
[/FONT]
[FONT=&quot]Batteries ran at below ratings usually so very rare for a battery to go bad, unless you are running voltage too high, which nobody does right? lol
Alternators expected to power 3-4 times their capacity & maintain a bank of batteries at the same time and when they end up burning up an alt, they go crazy
[/FONT]
[FONT=&quot]ORDER OF LEVEL OF TYPICAL ABUSE... IN MY OBSERVATIONS ANYWAY.
1- Alternator. (Most heavily abused)
2- Amplifiers
3- Subwoofers
4- Batteries

[FONT=&quot]I don’t get it..why is it someone would be more upset that the most abused component fails?

I see your point, but a fried sub or amp won't strand you in a bad neighborhood. :)
 
So what happens when an alternator is asked to provide more current than it is capable of? If for example my 80A unit is connected to the 10kw system. Does the voltage output from the alternator reduce down a level where it can handle the current, or until the next largest power source starts working like 12v ish when the battery starts contributing?

I mean, what is the failure mode of an alternator look like? Are they typically designed to fail safe or do thy tend to burn themselves out when overworked?

Like a subwoofer would get hot and need a recone kit. An amplifier would also get hot or maybe self-protect. A battery might overheat and do really bad things. You know?

When you pull more current than the alternator can do voltage drops to the level of the next highest source, which would be your battery. If you have an 80A alternator, that is the most it can do, the voltage doesn't drop so it can produce more current.

They just burn themselves up when they are overworked, that is why you see melted winding and rectifiers
