well u may not have to buy a new one...how many amps does your stock alt put-out........
also how many watts is your system going to be running on.
u could get your stock alt rewound ..............it would be a lot cheaper....and get yellow top......
well u could call your car dealer and he would tell u how many amps your alt puts out..
my guess is about 80amps..............
since your car is american made u should be able to get the alt rewound easy.......... but maybe u should get a new alt.......
here r some sites that sell performance alts
http://www.mralternator.com/
http://www.4alterstart.com/
http://www.alternatorparts.com/
http://www.h-o-alternators.com/alternators.htm
call them and they should be able to give you what u need for a price .....also check ebay......the second site is good and is also a ebay seller
well you current draw is too high........ a cap provides an impulse of enegy when the demand on you system is high............the cap is charged by your battery which in-turn is charged by the alt....and therefore if the alt does not produce enough current the the battery will get depleated ... cap or no cap...........
its kinda like trying to draw water from an empty pond

with 1900w, i don't think she needs all 200A...seeing that she won't be playing single tone bursts, i'm sure the amp's draw on power won't be constantly peaking.
Also, a high output alt will produce little power during idle (maybe even less than stock alts). I dunno about traffic situations there, but over here, cars stay idle most of the time.

With 1900 W (peak), I would think that normal daily usuage would add about 115 amps draw (that's about 75% peak power/volume). You also have to consider the stock electrical system. The stock alternator (105 amps) is designed with some give. So even with every stock electronic on (lights, windshield heater/wipers, AC, etc) the stock electrical is drawing about 60 amps. The stock alternator is probalby providing that (or near that) at idle....SO...this system needs about 160-175 amps total.
A HO Alternator, rated anywhere from 160-220 amps, will help keep the battery charged and the electrical system balanced. Even with a HO Alt and a fully charged battery, you may see your lights dim. Every car is different so some people may claim their vehicle doesn't. IF YOURS DOES, then a cap will help. As mentioned above, a cap can provide quick bursts of power, where an alt or battery can not provide as quick and large amount of power (typicall during bass tones, even quick ones. Also keep in mind that there is distance involved...the battery and alt are under the hood, where the cap is near the amp. The downfall to a typical cap is that they don't re-charge fast enough. Look around for new types of caps that have about 1/6th the charging time of a normal 1 farad cap.
There are some manufactures of HO alts out there, including re-winders/rebuilders that don't completely offer a high output alternator. What I mean by that is that they re-wind the alternator for more output. Yes, this does help the overall output, but typically the RPM needs to be increased as well. So, again as mentioned above, some HO alts do not put out as much at idle as stock atlernators. There are other parts in an alternator that should be upgraded to provide higher output at idle...again, some HO mfgs and re-winders/rebuilders do not do this.

I would speak with dom iraggi. I got a 200 amp alt off him for $340 which included shipping. I haven't installed it yet because I'm too lazy, but everybody says good things about him. You can find him on termpro and email him, or if somebody around here has his email address maybe they will give it to you. He'll be able to assess your situation and steer you in the right direction.

500~600rpm idle????? that's kinda low...VERY low...
