Upgrading my alternator

Whats the stock amp for a 99 alt. Im looking to upgrade so my system can run a little better.

Any idea on what size to upgrade to?
 


110 or 120A is stock I believe.

Find a local alternator shop, it'll be easier when it fails on you. Which it will.

The amperage all depends on what sort of amp you're running or plan to run.
 
ive had a system in my car for 3 years and hasnt failed me yet just want to upgrade it
 


And so I'd need to know the amperage draw of those amps to suggest a new alt rating.

Normally alts last 10 years or more, but when you put a lot of stress on them. they dont last nearly as long.

High output ones burn out even quicker.
 
Im running a 800.1 Ryval Phoenix Gold amp at 2 ohms to a Kicker L7 15". I have a 840 Watt Pioneer for my door speakers and deck speakers.
 




I agree with matt5112, just find a good, reputable alt shop and they can rebuild yours for higher output and you will end up spending less and it will be just as good if not better than buying a HO aftermarket
 
well if he buys a HO alt. online, his current factory one still works, so if it does fail, he can just swap back.

you can go either way with this one man, whichever u prefer.

sorry i lost the link to my HO alt. site...someone else can chime in on another site, i'm sure of it.
