Loudcav Posted July 29, 2009 Report Share Posted July 29, 2009 Id think that it would be limiting your amps ability to produce power but that is about all the load that 4 guage can support you deffinatly should upgrade to 1/0g wire with say a 200-300 amp fuse Link to comment Share on other sites More sharing options...
dred Posted July 29, 2009 Report Share Posted July 29, 2009 so what about the 80 amp fuse? Current Setup: 1170w : 14,4v = 81,25 A -> 6 awg / 80 amps New Setup: 1470w : 14,4v = 102 A -> 4 awg / 125 amps 06 Silverado factory oem alternator produces 120 or 145 amps depending on model. IMO looks like you can pull it off with 4 awg and a 125 Amps fuse but ... bigger is better. Link to comment Share on other sites More sharing options...
