I've been using the same 1/0 ultra flex I got from wedingsuply.com for the last 20 years almost, when I get a new car it gets new ring terminals and comes with me.
this is the best answerIt's not undersized. Good car audio branded wire is oversized.
There could be a whole thread about this. Lots of argument about cross section or surface area making more of a difference, if current travels more along the surface, ect.this is the best answer
welding cable has larger strands, and less them of them. "ca wire" has thinner strands, and more of them so it will of course be larger and more flexible.
papermaker is annoying as **** but he's right when he says that the ampacity of 1/0 is the ampacity of 1/0 (although he does it in a snarky "im smarter than you" way)
The 2 gauge I had before was welding cable...same brand.Yeah, sizes aren't the same as car audio wire. Was the "2 gauge" you had car audio or welding cable? If it was car audio wire that you replaced with 1/0 welding cable, the size isn't that different.
Car audio (Sky high, knu, tsunami, ect.) wire is larger than the standard used for welding wire. My Sky High 1/0 is the same size and my 2/0 excelene welding cable. My Sky High 2/0 is the same as 4/0 welding cable.
If your amps take 1/0 car audio wire, get 2/0 welding cable and you're golden.
Yes...partial to this also. I didn't wanna put a "strain" on my electrical if that makes any sense....and wondered if I should have went with 2/0 instead.There could be a whole thread about this.

Would have to measure the mass of a length of CA and welding 1/0 (without the insulator) and compare. If they have the same mass of copper, then I agree that they should have about the same amperage capacity, all other minor arguments regardless.
Has there been any actual side-by-side comparison with current flow through the different types of wire? If I still worked at the battery shop and had access to the giant carbon-pile load tester, I'd see for myself. Wouldn't be a tough test. Get set lengths and pass current through them to see how much they take before *poof* //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
FYI, The skin effect only occurs with alternating current (AC).There could be a whole thread about this. Lots of argument about cross section or surface area making more of a difference, if current travels more along the surface, ect.

yeah i definitely agree but im a standards guy, all 1/0 should meet the expectations of 1/0 if not exceed it (although exceeding it does reduce the meaningfulness of standards) so imo 1/0 ofc should definitely be able to carry whatever is expected of it at the set distance regardless if its ca wire or welding cableThere could be a whole thread about this.

look for insulation ratings if heat is a concern, the god emperor AvE always looks at degrees "science" ratings on the conductor as an aspect of overall qualityThe 2 gauge I had before was welding cable...same brand.
I got it simplified: Knu for my power/ground wiring, and welding cable Royal Excelene for big 3 because they can take the heat from the engine bay area. Not sure if the knu can so left it at that.
well i learned something, guess it is just ac, which makes sense considering the knowledge i learned states that AC quickly changes magnetic fields from pos to negative vs dc current which pushes electrons forward after they run into each otherFYI, The skin effect only occurs with alternating current (AC).
