Wiring My Car, Questions.

[rumproast789]

I have 2 of the same type of batts, then another one of a diff brand. The 2 have like 80 something a/h and hold like 1000 amps or something, and then the one has 100 or so a/h and like 1200 amps of storage. Stock battery from what I know up front, 200 amp alt, and I will be putting in a Audioque 2200d (unless I find a more powerful one for a better price).

I have 2/0 welding cable, a good amount. I was planning on doing the big 3 with this, then wire from the positive battery under the hood to the batteries in the back. I can't decide which setup to use, the 2 batts, single batt, or like all 3?

Would it be better to run negative and a postive to the back?

All I need for the back is to connect the positive and negative on each battery together or does one need to be grounded?

What size fuses should I use, the amp requires 200 amp fuse. 200 all around? or 150, then a 200 before the batts, and another before the amp? I dont need to fuse all batteries right?

Last one, negative on the amp to the battery or ground?

Sorry for all the questions, just trying to get it right.

If something didn't make sense, just say something!

IF someone has a good place to buy fuses for a good price let me know.

If you plan on using all three bats, dont think its a good idea, you say only two are the same. It would be better to use just the two same ones parallel.I would just ground the battery in the back to the frame, and run run power from front to back. Just fuse 12 inch from front and back battery on 2/0 i would say 200 amp fuse. If grounds are good amp can run to neg on batt.

Knu conceptz has good inline fuse holders and they come w/ fuses. They use 3 mini anls instead of one. $24.99

Think it would be better to use 1/0 cable, better current for longer distance, depends on car and how long the runs are

I think you have me mistaken. It isn't 2 guage its 2/0 as in 2 aught (thats how it sounds when its pronounced). I was thinking 200 amps all around then, right? also basically i'll need 2/3 fusess at 25$ each?

2/0 is better than 1/0 (0 gauge) fuse before every battery at <= 16 inches from the post terminals and if you want to fuse your amps go for it too.

Where is a decent place to get fuses, otehr than knukonceptz because I don't think I can pay 25 each for fuses...
