what's the amps on a stock alternator on 94 roadie wagon

I need to know the amps on my alternator. I need to up grade due to my car audio. I was told to use a 9c1 alternator and put in a extra battery cause its more amps than my stock one.

You already have the same alternator as the 9C1, 140 amps.

Old cars, just like classic rock... 60s, 70s, 80s, and 90s!

That's just a rating. My 9C1 alternator put out 174 amps at 2000rpm. Have yours tested by an electrical shop to find out what it's actually putting out.
