what kind of alternator and battery do i need with this car audio system?

[Leprechaun]

i have a 97 grand prix and i'm planning on getting two 12" alpine type x subs and a hifonics amp that powers them. somewhere around 6000 watts rms all together

What is wrong with you!!! 6000 watts is the biggest waste of money. but if you feel that you need an over powered system that will sound the same as two 12" kickers powered by a 200 watt alpine amp, go for it. get the Kinetik HC2400 for your battery. two Boss Audio CAP3.5R for your capacitors, and as for your alternator get anything that puts out more then 1500 watts and 12v and you should be fine.
