[QUOTE="Bob Saget, post: 7013987, member: 624160"] trying to wire up my Jeep..... confused with fuse sizes... I have 1/0 for the big 3, alt. is 136 amps, so 225 amp fuse? I know 1/0 is good for 350, but max output for the alt @ 160% is under 225. Also, I'm running 2 amps with a combined RMS of around 1,000w. Is 4gauge power wire fused @ 150 enough (assuming I don't have to worry about fusing @ distro block?) (sub amp is rated 600x 1 @ 12.5V & front stage amp 100x 2 @ 12.5V) I'd rather not go overkill on my wire & buy 1/0 if it isn't needed, not worried about having any headroom. I'm hoping a stock 136 amp alt., new duralast batt., & big 3 are all I need for this to maintain my voltage & prevent dimming. [/QUOTE]
