Hmm, I think I'm gonna have to do the big three and see if that helps my situation. Whenever I play "Hip Hop Drunkies" by The Alcoholics, at high volume, my "check Gauges" light comes on, so I ckeck, and my stock battery gauge is all the way to the + side... this has happened twice in the last week. I'll see if I can do the big three tomorrow. It's an 04 dodge dakota with 130 amp alternator and the system is sopposed to be a total of 550 RMS. Nothing bad has happened yet, still have full power, no dead battery, etc.
