90a alternator enough?

[DefiantGSR 10+ year member]

Hi, I plan on running a kicker zx250.2 and a pg x600.1 amp..I was just wondering if you guys think my stock 90amp alternator will be able to handle what's thrown at it. How do you guys calculate how much current amps take up?

If you guys dont think the stock amp is enough, what are some good HO alternators?

Thanks for the help..

Well, check the amp's fuse ratings. That gives a pretty good idea.

If you're not pushing shit to the limits it will be fine. I used to run a kx850.2 and a kx200.2 off a 95a alt.

i crank it up once in a while. no problems at night. around 1800rms, gains set accordingly. no dimming, maybe slight but not even noticeable. this is off my 80amp alt. i ran a single 1/0 power line to the back and 4 gauge to the amps.
