You need to talk to Joel at Best America, he is helping me design my system. I spoke to him last week and he told me that the only upgraded alternator for the X was so large that I would have to remove my air conditioner!
I had a 700 watt amp that did not stress my electrical system at all, even when playing for hours at competitions. Now I have over 10,000 watts of amps, so he has made me two gel cells and I have eight farad caps. He told me that a normal alternator upgrade will not give you that much more power and wasn't worth the money.
I am not sure if he was correct or not, but he does all the national champion spl cars.

Do not buy from them their stuff blew after 5 minutes and they won't warranty their product.
