Biggiest and baddest wire for going overkill.....

[SojiaRaggs9000]

I found this picture on a different fourm ... It seems to put things into perspective. From the right to the left...4/0ga welding...3/0ga welding...2/0ga welding...1/0ga welding...1/0ga Kicker Hyperflex...1/0ga Lighting Audio...1/0ga Knu Kollossus...2/0ga welding...1/0ga welding................

My only concern there is that to get the equivalent of 4/0, I'd have to run like 4 strands of 1/0, and at the connectors and terminals and what not it would be a lot easier to just have one big lug with the 4/0 than like (4) 1/0 lugs.The welding wire also has a really high heat resistance for under the hood, the Trystar is even double insulated.I can't have it all I guess

That is incorrect, 2 runs of 4 gauge will equal 1 run of 1 gauge. Not the 1 run of 2 gauge that you would think it would.

When you double a run it jumps up 3 steps not 2.

The calculator for this is close to the bottom of the page. Bcae1

pshhh $4 a foot for welding wire...i get that for free. working at a welding shop FTW!

Must be nice!

i think i have stinger wire in my car and i havent had a problem with it at all

This is a great topic. my whole car is wired from welding suppy. right now i am in a search for 3/0 or 4/0 wire, but the only thing holding me back is how do i connect it to my amp, if anyone knows where to get 3/0 reducers to 1/0 or a 4/0 reducer to 1/0, chime in. Welding supplys shipment is extremely fast FYI

I think we're on the same ground here, we're just looking at it two different ways. At least here's how I see it:

A single strand wire will be able to carry more current than a wire with multiple strands. Period. There's no contesting that fact. The thicker and shorter the wire, the less resistance it provides.

In terms of feasibility in a car audio application, you want the wire that will give you the most cross-sectional area while maintaining the most flexibility. There's two ways of looking at this. The more small, individual wires there are, the less space in between them, so it almost acts as if it were one big wire. However, the two are not the same. The myriad small wires have the same cross-sectional area as one big wire, so they can carry the same current. But, on the other hand, they still act as hundreds of small wires, so they build up more resistance than one thick wire would.

I'm not disagreeing with you on the cross-sectional area. I know it's the same between them, whether you have one thick wire or lots of little ones. My point I'm trying to make is that one thick wire will build up less resistance and outperform hundreds of little ones. That is science. However, I will agree with you that, within the context of car audio, a higher strand count is very desirable. It maintains the cross-sectional area while allowing much more flex.

For car audio applications, welding cable is just as effective as Fleks cable. The cross-sectional area is the same, so they'll handle the same current. The distance of the wires in the car is not enough of a factor to make strand diameter into much of a factor, so the two will perform equally. The only difference is the amount of flexibility you're going to get out of the wire. Oh, and how much you're going to have to pay for it

x2 on this 100 percent. 1 fatty wire will have less resistance than a bunch of smaller wires.

I think some people are getting confused about the difference between 1 AWG and 1 Gauge.I'm seeing some mixing of terms here.That picture on post 41 though is a great find by the way SojiaRaggs9000.

My question is mainly about the last paragraph.What size welding cable is equivalent to 1/0 Knu wire?

2/0 ... look in the picture i posted there is 2/0 welding wire next to the knu. Also the welding wire pictured is from tystar.
