go online to courtesyparts.com it is nissan dealer in texas and look at online parts and look up the alternator for your model and top model of same yr or 2-3 yr previous and post models and compare part numbers. Maybe they have more amps on other models. Or call autozone and have them pull it up and see what amperage is on yours etc. Most likely unless you install a real high wattage system you should be okay on stock alternator. My 91 has ac power steering etc and I have a set of 2 amps pulling close to 600 watts and no problems.
