[QUOTE="thatsgonnahurt, post: 2412385, member: 568918"] well that's a different story. where did you get the 4000 watt figure from. so at full power it will pull 70 amps. with an average current draw of say 14 amps figuring music with a 20% duty cycle. you will probably be fine with your stock alternator.
