Wire keeps coming out of crimp connectors.

You weren't kidding when you said they were expensive. I'd like to see what the crimps look like.
Do you have crimpers for large (e.g. 4 to 4/0 gauge) terminals? I have a cheap (less than $20) anvil-type setup that you use with a hammer. It actually works quite well. I wanted some handheld ones but they are ridiculously expensive. Here is what the crimp looks like done with the cheap device I have:
It is an incredibly secure crimp, but the device is not very convenient to use due to needing a solid surface to rest it on and swinging room for a hammer.

you know that electricity only travels on the surface of the wire right...and not through it...?

Skin effect only applies to higher frequencies. At DC, we use the whole wire, IIRC.

That's true. The topic comes up in car audio forums a lot, usually in discussions about whether power wire (from the battery to the amplifier) with a high strand count is worth paying extra for or not. Some people cite "skin effect" as a reason that a higher number of fine strands (giving more surface area) is useful for power wire. That's not the case. In this context, solid core would flow just as well as stranded. However, the higher strand counts do add flexibility, which is useful for installation in vehicles.

Nope. Any wire larger than #4 gets a compression lug with a screw around here. I had to sub out some 0000 jumpers that had crimp lugs.

Its some mil-spec. Price goes way up. No digicam here at the office with me, but I'll try to remember to take one home to take a pic of. It makes the insulation sleeve square, with indents for the wire. Looks slick. Not sure if its worth the cash tho. One customer demanded that particular tool, so they paid for it.
