I have a 1991 Nissan pickup with the 2.4L 4 cyl KA24E engine... does anybody have an idea of how many amps the stock alternator is? I was thinking around 50 - 60.

Thanks

Should be about 60 amps. You can get a 90 amp 240 alternator on there but you have to change the pulleys.

I see, thanks. I'm wondering approximately how many watts I can run on a subwoofer amplifier, without having the lights dim... I guess there's no real way to know without trying.
