Just wondering the difference from welder caple to audio power wire. I can get 45 feet of 2/0 welder cable for $100 from work.

 

it's better

 

I concur.

 

its welding cable, and I ran a single run of cheaper 4 gauge, up graded to a single run of 1/0 welding cable, and ground, now I have no dimming and my voltage is way more stable + I'm even using a bigger amp. Its good stuff!

 

u would have seen an reduction in dimming either way, because u went from 4 to 0, and a better ground, so ur statement there doesn't really matter in this case

 

I use it too in my SQ car

 

welder cable with shrink wrap > streetwires crap

 

way better than car audio cable the stores sell.

 

Well thats awesome to know!!! I just bought 300 feet of 2/0 hahah its stockpiled in my shed if people are looking to buy some.

 

Up until a couple of years ago the argument could be made either way. Now with most car audio cable being copper clad aluminum or just straight aluminum and most welding cable still being pure copper, I believe the welding cable superior.
