If so , then crimp , if not - soldering is OK. What I have seen happen is there is movement , vibration or flexing , a soldered connection has a high failure rate from metal fatigue at the point of the solder. I did a lot of mobile work and learned to try to reuse some crimp connectors battery and others , many times the dimple crimp for the most common type of crimp connector , would cut some of the strands when you get just enough pinch in the dimple to keep from pulling apart. After the lack of a picture and not quite 1, words ; I have not seen one of these fail - if done correctly. I ended up buy off the Snap On truck a 3 foot long crimper like this for battery connection , and welder cable.

Nasa tech standards - Crimping, interconnecting, cables wires. Had an interesting bit about failing gold coated connectors where the layer of gold actualy develops microscopic cracks. Also specificies acceptable cleaning compounds and many interesting things. I could see many of the errors I used to make in standard constructions, and even some I didn't know were errors, or at least not up to NASA standards. Find More Posts by Nordic.

Thanks - even tho I don't plan on taking my amp to space anytime soon, I'm sure this will be useful. Fascinating stuff. Great document, but surprised they don't mention the fold-over-each-other splice that I have used in places I don't think a side-by-side splice is strong enough. Find More Posts by richie00boy.
