Going to be using it for battery relocation. 0 gauge amp wire is preferred. This stuff is so expressive in stores. Just wondering if anyone had some.

 

go to ur local advanced they have 50 ft rolls u can buy by the foot for cheap

 

why 0 ga? 4ga is the biggest you should need to do a batt relocation....and make sure u fuse both ends for batterys

 

Why do you need to fuse both ends? Current is current, if the wire shorts out on the chassis for some reason, or something happens, the fuse pops and stops the flow of electricity. What is the advantage of having 2 fuses? Am I missing something here? Are you talking about a circuit breaker between alternator power and the new line that runs to the back?

 

I'll check them out; however, I hear they use a grade copper wire that is quite brittle and can break within the insulation.

 

Umm what?

Why do stereo guys use 0awg just to run amps then? That wouldn't make sense, oh wait it doesn't.

I use 0/2awg and you can buy it at welding shops or on ebay in all kinds of colors.

 

You should only use 1 fuse closest to the batery. Summit sells 2 gauge batery relocation kits that are junk! Its not even thin strand! Sold that crap to a honda ricer after it killed a optima batery and my car never wanted to start with out a jump!
OP is right 0 guage amp wire is your best bet. I was going to get some off egay but it went up from 50 to $75 for 50 feet of 0 guage amp wire. Its not a good deal at a auto part store, BET! Now I just run a miata batery to clear the intercooler piping and never had a problem.

 

well actually it makes perfect sense because amps can draw a ton of power an u need that ga wire to handle the current as where your just relocating a battery and only charging it slowly....and just FYI most cheap 0 ga on ebay is not anywhere near true 0 ga.....true 0 ga is a high strand count(small copper wires) wire that is roughly almost a nickel sized diameter and im not talking about the insolation as well...im talking copper size

 

well because a nice wire is expensive and your trying to protect both sides so you dont burn up your wiring.....i sure as heck dont wanna mess up a 100$ piece of wire when i can just blow a fuse

 

The only drawback to using too thick of a wire is weight and the pain of running the cable. If you run too small, resistance / heat will go up and bad things could happen. Say if the wire gets hot enough to melt away part of the insulation, and it grounds on the chassis. You do not need to fuse both ends, just fuse it as close to the positive battery terminal as possible.
