Seth Touchet Posted July 25, 2014 Report Posted July 25, 2014 Im doing the big three on my truck and i was wondering if a 200a fuse was good enough... For now i only have a 750 watt amp but i should be getting a aq2200 in the next few months.. I have a stock alternator and stock truck battery
hoit Posted July 25, 2014 Report Posted July 25, 2014 I may not be the best candidate to go first...but I'd do a 300...at least that's what I"m gonna be doing for mine... :-/ 2007 Chevy Aveo Ls sedan 2 Sundown Xv2 on scv4k @ .5 ohm 2 pair RE XXX 6.5 components on sax200.4 @ 2 ohm Big Three, Three runs 1/0 power from front to back, 1 ground front to back Two runs ground from rear bank to chassis XS power d3100 upfront, 3 Odyssey 2150s in bank Singer 220 amp alt
philrab Posted July 25, 2014 Report Posted July 25, 2014 Fuse to the size of the wiring. That's always the ONLY correct answer. You want the fuse to blow before the wire melts down or starts a fire. 2015 Toyota Tacoma Build Thread 2007 Mazda 3; 5000K HID's, Kenwood Excelon KDC-X997, Infinity Reference 6.5 comps in front and coaxials in the rear doors, JL 320.4 four channel, Rab Designs built ported enclosure with an SA12, Kenwood monoblock, Redline Leater shift boot/e-brake boot/center console cover, JBR short shifter/shifter bushings/rear motor mount.

FocusOn20s Posted July 25, 2014 Report Posted July 25, 2014 300a fuse would do you no good. Wire for the amperage of your alt, then fuse for the wire I have a 150a alt stock, so I used 4 gauge OFC for my Big 3 and used a 150a fuse
Seth Touchet Posted July 25, 2014 Author Report Posted July 25, 2014 Im using knu koncepts 0 gauge cca wire
mothra Posted July 25, 2014 Report Posted July 25, 2014 no fuse if nothing changes, nothing changes You don't know what you don't know, till you don't know

Omega5002 Posted July 25, 2014 Report Posted July 25, 2014 No point in fusing the charging wire IMO, if the factory didn't fuse the stock, then why bother, just run the wire correctly, away from anything that can pinch/cut it, preferably along the stock charging wire. 2003 Kia Sorento Team Subsonic LowsTeam Bassin' on a Budget2016 Rebuild Under Construction Best score: 150.2 at 40hz (3k, 2 Custom HDC3 15's) Usaci style(door open, in the kick)
