Dont ever use pliers to crimp any terminals, it wont give a secure fit around the wire. If they are very thick just use a hammer.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
i use a vice on anything bigge than 8 gauge and just slide some heat shink tubing over it to give it a clean look.
btw, 10 bucks is a rip off for those terminals.
