Thread: Battery Relocation Question

Would 4 gauge wire be to small to use? I have some left over from the previous owner(amps and sub lol) and there is plenty to run to the trunk. Its 4 gauge speaker wire with a 100a fuse on the wire. I went by the stereo shop today and asked how much 0gauge wire was and he was going to give it to me for $100.

I think there is a write up about this one the 'other' forum, just a sec....

And a nice little quote from chriscar himself...



From that I'd say you'd probably be pushing it.

its probably just going to be temp for now. I see people using Wielding wire?? anyone have info on that?

im using 4 gauge wire on my car in hot az. weather so far so good... youll be fine..

I had to postpone it because I realized I didn't have battery terminal connector for the wire. lol

What about Welders Wire? Anyone use that? And where would I get it other then the obvious.

4 gauge is fine, when starting you are drawing maybe 60A's, when running you are no where near that, maybe around 20-30 depending on what accessories that are on. That rating is also continuous, peak is probably double that.

My friend is using welding wire in his car, works fine I guess

Welding wire will work, but they are sized differently that car audio wire. Welding wire is actual AWG size while audio wire is bigger. So 4 gauge in audio wire is about 2/0 in welding and 1/0 in audio wire is about 4/0 in welding wire. Check this link out, take the diameter of your wire and see what it compares to. As long as you fuse it correctly you should be fine.

I got my 0g wire at Advance Auto for $3 a foot. I used 10 feet I think.

The benefit of welders wire is that it uses very fine stranded wire which makes it more flexible than the average battery cable.
