I would try to buy some copper or aluminum bolts if you can find them. Copper is about 60 times more conductive than stainless steel if I did the math right.

Comparable sized welding wire is just as good if not better for moving current than all three of them, and much cheaper. Also pure copper welding lugs are much better than ring terminals for current flow, and they too are cheaper.

Yeah, he probably wont notice a difference as long as it is the right size. Dolly Parton's boobs would actually make a really good enclosure =P

Not sure if I'm breaking the rules by doing this, if I am please delete my post. I found this interesting read on MP3car.com written by a guy who at least seems to know what he is talking about. Also he is a bit of an ass hole; just a warning. Coppied from CoolBlueGlow of MP3car.com:

You're right when you say box shape matters more for ported, but it still does matter for sealed. A rectangular enclosure is better than a square, and a trapezoid is even better than that. The perfect enclosure is a sphere do to it having no parallel sides if I'm not mistaken. Dampening materials such as deadener or pollyfill will probably be more important than shape though. And to be honest you probably wont notice much difference between the shapes, but IMO you should just build the better box unless you have a good reason that you can't.

The optimal ratio is ~.62:1:1.62 according to acoustical engineers(the ones who know what they're about)

Copper is, aside from silver, by far the most conductive metal. If copper is 100 on the conductivity scale aluminum is like 57 and gold about the same as aluminum. Pure copper soldering lugs are going to be the best by a long shot, other than them tarnishing. Gold doesn't really tarnish or corrode so if it's going to be exposed to the elements then gold plating would be helpful. About the terminal you bought, just see what they are made out of to tell whether or not they are good. Really the metal is all that matters, everything else is just marketing.

Wow $800 is ridiculous! Just find some people to help you build the box and get dimensions from this forum. I usually build boxes for my friends for free minus supplies, didn't know I could turn a $750 profit doing it

Yeah I guess that was a bit on a contradiction on my part, sorry for that. My main point is that if you got say 2/0 pure copper welding wire it would be just as good or maybe a little better than an equal 1/0 knu wire, but also much cheaper. I just don't really like how people always recommend the wire that is 50% or so more expensive than welding wire yet does the same job. It seems like if people want to know the best wire for the money then people should be less inclined to recommend a name brand wire that just marks up the price because they have "audio wire" hypothetically written on it.

That's only AC current, and if the small strands are touching they will act as a single wire give or take. but it's DC current so cross-sectional diameter is what matters for current flow. Also, about the voltage thing this is a quote from boon explaining it. "Current is how many electrons are flowing through the wire and voltage is how much energy they carry... " just to clarify voltage/current

No, if you have say 1 pound of pure copper the more strands you make it into the less conductive it will be. If it's all in on thick strand that is the most conductive and least resistant option. Also, the knuconceptz is tinned in something that isn't copper so it would be less conductive than pure copper than a comparable sized welding wire for both reasons. The smaller strands just help flexibility. Yes it means less gaps so they fit a little more copper/tin per diameter, but If you get a size up in welding wire that would be more copper per foot and thus less resistance. You can buy 4/0 100% pure copper welding wire for the same price as 1/0 knu, it's all marketing. Scroll half way down this page to check out the 4/0 wire in action. Team Broke Ass F-250 (thanks to jburt09 for the link I stole it from another thread you made.)

You can get 4/0 pure copper welding wire for the same price as the 1/0 knu stuff, and the only difference is a little flexibility. EDIT: Also, welding wire has less strands than knu so there is less resistance and better current flow.

I would just make a fork shape out of the copper wire, it would probably give you a better connection than a spade anyway. only negative is it might not look as shinny...

Wow fail, I bought a 1200 two days ago :censored:
