Maximum out put from battery/alternator

[MafFilms]

Being the person i am, that always wants to up the ante, i want to throw in some more powerful subs and amp in my 95 camry. But i do not know what the battery/alternator can handle.i heard the battery and do 30-60a, and the alternator 80a Im looking to power 900watts(maybe 1500watts later on depending on what i can get), am i good with stock power for the 900watts, or will i need to wire extra battery or what not? Could i just get another battery and hook that up and have 2 batteries, or should i go with a higher quality alternator. Please post feedback.

EDIT: ^^^^ I currently have a 500 watt(300w rms) amp in my car, supposively needs 50amps(adding fuses togehter), it runs fine. so if i want to put in a 1000w(800w rms) amp that has 60amps(counting the fusues) will i need any extra add ons in my camry. Thats the setup im looking to get at. Let me know

Do some reasearch and maybe post some more information. What car do you have? I know in my cam. I have an 80 amp alternator and that handles my ~300 watts system no problem, but when I upgrade to my ~1000 watts, I'll be investing an an HO alt.

To top it off, there's been a lot of discussion re: batteries and alts, so search around here and you'll find something.
