Auto Parts: alternator, 1998 infiniti qx4, infiniti qx4

Question
I'm buying a rebuilt alternator for my 1998 infiniti Qx4.  The auto part store needs to know if I need a 90 amp. or 100 amp.  I'm not sure which one I need.  Can you help me?

Hi Heather,

Sorry it took so long for me to get back with you, I've been having trouble with my computer and had to fix it.
Basically it is up to you. If you have power windows and locks and anything over a stock stereo, I'd go with 100amp. If you have manual locks and windows, and a stock stereo, you'll be ok with 90, but if you ever plan to upgrade your tunes or anything you'd be better off spending the extra bit and shooting for 100. You can't go bad with more power.
