Dude a GM alt pumps out like 140amps. Unless u have one kick ass system I don't think its your alternator. I could be wrong. Just my two cents

a stock cavalier alternator is 105 amps. after all the electrical needs of the vehicle there really isnt that much left for the bump. I can make my car damn near stall with the stocker in
As far as alts how big do you want to go. having the 2.4 limits you in the fact that you cant use a large case gm alternator and must use one the same size case at least. I believe you can get one up to 200 amps though. Just not the 300 as with the large case I paid about 440 for my 300 ampers from Dominick Iraggi of iraggi alternators
You can email him at dominick@yds.net rick at HO alternators also does them as well as Nate at Excessive Amperage. Nate's contact is Nate@excessiveamperage.com. Unfortunately I don't have ricks contact info. You could also find one from Ohio Generator or Powermaster or Even Stinger if you choose. Just be prepared to pay more money for one.

As far as batteries go. I'll throw you some names. Optima, Powermaster is making a 12 volt battery, kinetic, NSB, Digital Designs has a battery that is un real as does cactus sounds. Hope that was of some help.

is it safe to be running 3200 watts thru 4 gauge? i dont have the chart in front of me but that seems a bit small to me.
