alternator ideas?

i want a higher capacity alternator. what woiuld be the biggest and and where would i get it?

i'm wanting to run square baja style lights on the roof basket (4 in front+ 2 on each side+ 2 on rear--with each side switched independently--possibly all on at the same time) a little like this: http://www.planetisuzoo.com/data/articles/98/IMG_2295-me.jpg

plus 4 lights on a brush guard in front.

do they make a 180-200 amp alternator that fits the 99 passport 3.2 v6?

is it a one wire "plug and play" ? i may run a dual battery set-up soon also.

good site for Isuzu Audio. There are few here with big systems.
