You can do what you like for all I care....

But FYI you are talking to a chemist... not a wire marketeer

 

I've never had a problem, but I've been told that underhood fluids could break down the jacketing on welding cable. Maybe this was from an overly cautious source.

Anyways, I don't know how you can debate the fact that Cu = Cu.

 

I think my 3/0 cable uses butyl jaketing... (also inert for all intents and purposes)

I can't answer for all welding cable versus 'marketed' wire..... but yea, I run 3/0 philips........... can you even buy wire that size at your local mobile audio dealer ???

 

I have dragged my arc welder's cables through just about anything that can leak out of a car over the past 12 years and the cables are still fine. If your car is spraying fluids all under the hood, is the car worth install anything into in the first place?

 

I have some of each in my car.
The welding cable has fine strands, put they're all single, the stinger wire is braided, so more flexable.
The welding cable is copper, not OFC, and is not plated. It will corrode where it is exposed at the connections.
The stinger wire has a plating on every strand, thats why it looks silver, won't corrode as easy and solders to connectors easily. That's why it's expensive.
My welding cable is only in the trunk, so it stays dry.
The Jacket on the stinger cable is already deteriorating under the hood.

The car cost a small fortune and the system cost 3500, who cares about a couple hundred for wire

 

You really should check stuff out sometimes before spouting off. Working in the chemical pumping field, I deal with elastomer compatibility issues every single day and the LAST thing you use on gasoline, diesel, anything with any petroleum products at all in it is neoprene.. These compounds cause neoprene to swell, loose strength, and crack over time.


For interest's sake since you borught it up - PVC is alright to use with diesel, most petroleum products, and leaded gasoline but not unleaded gasoline.
Really, neither is an ideal product under hood and a good reason to use split loom tubing on all underhood cables.

 

^ blah blah blah

dukk neoprene is one of the most chemically reistance polymers there is.... and I know that for a fact.... go ahead and read duponts patent, you might lean something

 

Your last point may be valid.... but 'OFC' is a marketing ploy... and IMO the main reason car audio power cable is tinned is for aesthetics... why else would you add resistance to 20' of wire when its only 2" on each end where you need to worry about corrosion ?

 

I'm pretty much done with you're BS attitude.

You think I make this up like you? Instead of profiling, how about you think for a single second before you reply.

This is part of what I DO every day as an application engineer, not some internet dipshit...

Here's a couple of links to some free chemical compatibility charts. Click on Neoprene and then scroll the chemicals. Lets see who is full of BS idiot:

ok it was just a simple question, this topic is a little out of hand now. So from my readings, yes i could use welding cable however it can not handle the elements over time. Audio wire it is... Craka where u at!!!!
