Sabi ng electrician ko eh 100A daw kasi yun naman nakalagay talaga na rating ng fuse sa fusebox. 60A lang pinaka-mataas na inline fuse ( para sa audio upgrade ng cars

) at 80A naman yung plug-in, yun na nga lang ata ang improvised ko na fuse sa +battery to + alternator kung ay 100A na plug-in type gaya ng sa fuse box yung square type.

Gauge #8 binili ko, columbia yung brand. Walang branded eh, P79/meter lang. Tapos eye terminal na tig-P15 isa.

hay, in-line fuse na lang talaga kulang para guwapo yung grounding sana at mas secure.

checked mine and 100Amps nga yung galing alternator. pero kung gauge 8 lang ang wire mo 40-55Amps lang ang current capacity nyan. 40 amps fuse should be ok.

Sure ka? Baka masayang kabit ko ha at pumutok lang fuse.

sabi kasi dyan kaya ng wire gauge #8 ang 100A eh. yung mas maliit ang 60A.

Bakit po gauge 8? big three is actually gauge 4 minimum, the stock wiring is already ahead of gauge 8 or more than, the bottom line here is that "to maximize current plow", larger wire the better, i don't think gauge 8 do something there..
About fusing, it's not about the current ability of the wire, it's about the safety of the alternator, when your system needs larger current that the alternator cannot supply, the fuse is blow rather than the alternator,
You must read these and understand fully to make sense these big three.. http://forum.sounddomain.com/ubbthre.../312025/page/1, work these fully with no mistakes..

Damn, that is what my electrician mentioed, I forgot to bring the vehicle kasi and we just talked over the phone.

Papalitan ko na lang wire tom. Gauge 4 nga pala. Still I don't have the 100A yet. Hindi pa din puwede maunpisahan.

I don't think gauge 8 can handle 100Amps, it's just too thin.

mag observe din po kayo mga sir sa bibilhin nyong materyales, lalo na ngayun na maraming nagkalat na fake na wire, marami po ngayun yun may halong ibang materials na namamagnet, be sure na lang po dun, isa pa po yung makapal lang ang balot pero inside, almost gauge 8 na ang gauge 4, mga palatandaan po ng mga low class na wire is yung namamagnet, yung mga strand nung wire is madaling maputol at ang isa pa is yung magagaan.
Real wires po is oxygen free wire, the higheir strands stands for the best quality wire and plexibility, pure copper wire delivers maximum current flow even in applied heat and cold extremes. Sayang, mahal nga lang ang mga branded tulad ng kicker, tsunami, conections from Hertz, and more, in our shop, i uses firland wires, firland since is pure copper but has a difference in number of strands like branded, but at the same time, it also perform like them, the pictures follows as sir jedi post what i did in his car, it's actually working today, as i did the big three followed by the replacement of the old power cables, wew, his car sound hear inside and out clearly.

Most use 4GA since it has a max ampere capacity of around 100+ I believe. So unless aftermarket alternator yan, you'd hardly benefit from gauge 1 or 0.
