Sup guys, a couple months ago I installed a DC Power 250 Amp alt, replacing my stock GM 105 Amp alt. I have a 1997 Chevy 1500 Cheyenne. The plug that goes into the alt is only one pin, not 4 like I usually see for the 1500. My question is, the voltage is only above 14.1-14.3 when its cold, and obviously id like to run a little higher and I don't know how my alt is regulated, and if its internally, is there a way to regulate it externally. Other info is I have 1/0 OFC big three and power wire, a 1/0 CCA negative run back to the front batt and 1/0 OFC grounded in the rear, a 50ah Juicebox in the rear and a stock napa up front. I'm running a MB quart 4.60 and a custom American bass similar to a 175.1 which is about 2-3k if I remember. I'm currently running my amp at .5ohm and drop to easily 11.5 but I try to keep it above 12.8. Any help is appreciated !
