Does anyone know the size of the stock alternator in a 2013 OS? I am not even 100% sure where it is located. I am planning on installing a decent sized stereo system, so I want to do the "big 3" upgrade first. I know it has a pretty tiny stock battery, which will be changed out as well, but I can't seem to find any info on the alternator itself.

 

Not sure if anyone of our members have replaced/modded the stock alternator..

The stock unit is a re-gen unit that cost ~$1,500. Just a heads up.
