Upgraded Alternator question...

[BigBlackTrain]

So I have searched the forum and I am really trying to find ot a couple of things... Does anyone know the ratings, Amps, Voltage, etc of the OEM alternator on a 2003 Yukon Denali, 6.0L. I was looking to upgrade because I am drawing a lot of power with my Train horns, Hella Black Magic lights, Stereo, Amps and so on. I was looking at the Promaster 225 Amp from Summit Racing.

Any suggestions? Thanks in advance.
