Question about big 3

[Compjake 10+ year member]

Okay, I'm just curious. Should I do a big 3 on my car when I'm only going to have 2 110amp alts and all the stock alt wires are already 4awg? I know I probably should but if both alts only put out max of 110 amps then shouldnt 4 awg be plenty?

Why do you have 2 110amp alts? Why not just go with 1 HO alt?

Go with the 1/0, it will be easier to upgrade, and have less resistance. Not to mention you'll know it's done right so the stock wiring won't fuxor itself later.

I was just curious, so I will prolly only run 0 for the second alt and just keep the 4 + a 0 for the stock.

and im going with 2 110 amp alts becasue I can buy a second one for just over $100 core included.. now could I buy a HO alt with 220 amp for the same price? probably not lol

If you have the means to fabricate a bracket, 99% of the time it's cheaper to run dual stock alts than it is to run a single alternator that puts out the same amperage.

Do the big 3 in 1/0AWG. Should just help your charging system be more efficient.

The brackets will be easy, it will bolt on right over my power steering pump and I only need a bracket on the top witch i can bolt to the AC compressor. then just use the original stock alt to get the right tension on the belts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
