Huge wire

[irpirate]

dunno, just wrote what was listed on the thread lol.

As for multiple alts, have them all charging to the front battery and 2 runs of this to the back would probably do.

Easy 2000 kcm is FUCKING expensive lol and usually you dont want 2000 kcm you ever try bending a 500 Kcmil before its a FUCKING Bitch man its not as flexable also compared to the 1/0 that the companies use

[trulywickedcustoms]

no† to men†ion the people with draw requirements like that normally have multiple alts so one run is kinda impossible

I had been giving some 500 or 700 wore some thought before I got a killer deal on all my 2/0(used)

But IMO you could do a buss system up front too, 2 or 3 charge lines off each alt into a block custome milled to go from say 9 inputs (3 charge lines on 3 alts) to 1 big 700 series wire and the same when you get back to your batteries or amps...

And I wouldn't do them all to the front battery dependin on the size of your battery bank 9/10 times youl be bottle necking your power and over charging that front battery

larger wire isn't always practical either with 1/0 you can squeeze into place you couldn't with larger wire...

Mayo has that in his trailblazer front to back

skin effect is A/C primarily.

you don't have to have a single conductor to carry the current, it can be divided into multiple conductors. 4 paralleled 1/0 gauge wires carries a total of (assuming 300amps each) or 1200 amps. Each fused according to the individual wire and not the total current draw of the circuit.

How in the hell would you hide and or bend wire that thick?

The availability is much lower for wires that size and the cost is much higher. The car audio industry has centered around smaller gauge wires so it just ends up being cheaper and easier. Amps, distribution blocks, etc...are all made to fit with 1/0 or smaller wires. Beyond that, there really isn't readily available products for car audio.

That's some huge ass wire

I'm not worried about flexibility as much. Some of this stuff is considered 'non-flexible'

I'm talking about VERY LARGE systems only - snaking a dozen runs of little stuff around is dumb.

I usually run along the frame for 1/0 anyway.

You cannot run 300 amps per 1/0 cable - that is just incorrect. 150 amps is closer to reality, but even that is pushing it on a long run. The more you push it, the more your voltage drops. You'll get a big sag in voltage, even though you may never pop the oversized fuse or burn the cable.

If you can get 150 continuous amps, in reality, on a run of 1/0, then a single run of 2kmcm would be the equivalent of 10 runs. Run 15kw of amp power with one cable, and very little voltage drop. One buss up front, one buss in back.

I pulled up a couple companies that make connectors for the stuff

and here's a 650mcm cable, for some more perspective.

And how do you guys know how expensive 2000 mcm is? Or even 750? It would be a better bang for the buck than 1/0 at $50/ ft.

To clarify - I only say that because I use high end hardware. I generally avoid 'car audio brands' because ALL lugs, fuse holders, terminal connectors, and blocks from these companies I have used rust out quickly in my climate.

Would love to see it in a car. Would look crazy but people love the "wow" factor of stuff like that.
