Lets Talk Open Barrel Crimpers - Reviews and Discussion
I have an MSD crimper (the ignition box MSD people) that works well.
Like a lot of other guys, I generally crimp then solder anyway.
If I'm doing something that doesn't require 'stock' type terminals, I'll use WeatherPak or Delphi connectors.
For bigger stuff, like 8ga+, I'll use my big Molex crimper, crimp connectors, solder, and heat shrink.
