Largest Alternator needed

[suzukimph]

What type or brand alternator !

I started to searching for one. I couldn't not find reliable aftermarket alternator.
Looking for large amps, can't possibly take.

Any suggestions where to purchase online or local, for:
2018 CHEVROLET SONIC LT RS
HATCHBACK 4 DR
1.4L I4 F DOHC 16V

Thank you very much
