Feather in my Crimp hat
Crutchfield Customer Review (What's this?)
I threw these in my cart as an impulse item with my recent upgrade from factory stereo to aftermarket headunit, and OMG! I will never do another install or repair without them. Strip your wires (about 3/8") twist them together, slide one of these puppies on, crimp it, & move on to the next one. Perfect every time, and the bees knees for 12 V stereo stuff. So much better than wire nuts, or trying to solder and heatshrink or (heaven forbid) *tape* things together in a car. These make a great electrical connection AND a solid mechanical connection in one step. I'm converted.
Pros: Quick & easy solid mechanical connection won't vibrate loose
Cons: Single use
