I got 2016 ram 1500 express 5.7l 5in radio no idea on alternator size if you know lmk but I was told if I upgrade it won’t matter I’ll still get the same amps as the stock since the pcm controls the regulator any input I need about 190amps for my audio

 

Looks like they came with anything from 160 to 220 amps. Need to have a look at yours, and see what ya got. No point spending money on something you don't need.

 

I’ll be running a 5k or 8k minimum draw is 200 amps so I’ll need one or the other but I tried finding a part number but couldn’t I’ll have to take it off I guess

 

Should be a label on it somewhere.... *usually* they are right on top..... but hey, ya just never know.

Pulling a build sheet for your truck might tell you as well.

 

Thanks for that link!
