I disagree, and that being said I've done this for 10 years and have never had a crimp cap fail on me. The one time I looped it like swo was saying is the one time I cut the wrong pair and connected the wrong end to the speaker. Couldn't figure it out until I realized what I must of done a few hours later. Had to pull the speaker down and re do that area. And slitting the wire takes more time then not especially because most of the time 14/4 has a fine twist to it (atleast ICE and snap do)

Much easier to strip and crimp at the first speaker because you already have it stripped to connect to the speaker!
