Alternator Size?

[SPL 10+ year member]

Hey guys, I currently have a Orion 2500D and a Orion 6002 that is awaiting installation. But I have one question, what size of alternator do I need?! I have allready upgraded the BIG 3, have a red top running under the hood, and have a yellow top in the back. I am using 1/0 awg power/ground wire throughtout my install. I was thinking 200 amp alternator for my 02 monte carlo ss, but am now having doubts because I know nothing about how big my alt needs to be. Please help me I need BASS!
