you can get away on the stock alternator for a while, but the longevity of it is going to be uncertain when hammering on it.

Read up on the big3 mod, and get a bigger/second battery, and you should be fine though.

Unless your running like a 70 amp alternator, i dont see any issues. If you get crazy dimming and voltage drops, you know you need to upgrade.
