Wire ferrules are a thin copper tube that is tin plated and they really help to clean up our car audio installs and make them more robust. With a wire ferrule we can prevent wires from fraying, we can easily un-install and re-install the wire multiple times without issue, and the wire ferrule securely attaches to the wire in our amplifier or processor. But when do we crimp ferrules and when can we use the amp terminal to crimp them with the set screw? What ferrule crimper works well? Let's find out!

      For us (me) less familiar with determining the gauge of a wire. If the wire gauge is not identifiable on the wire itself, is there a tool you recommend, so the proper size Ferrule is utilized? Or, is "by eye" the go to method for this technique. Appreciate your informational videos!

      Those are called "Phoenix" style connectors :) They're often used in Pro Audio and high voltage amplifiers.

      I got one of these for my zero gauge wire when I went to put it in my fuse holder it wouldn’t fit the zero gauge connector in the fuse holder how can I get a Ferrule to fit my zero gauge and still hit in my fuse holder zero gauge fits fine without the ferrule

      I would finish off soldering the power wire ferule with silver solder to help seal out air and prevent possible corrosion and oxidation.

      Pretty cheap tool. Imma order one before i clean up my install. I did it 3 years ago and said it was temp install just to test it out. 3 years later and i am ready to do it. After i get this tool to make it look even better.

      I have a question. I have Fusion hybrid and would like to add my base box. It includes a Sony 8” sub and a kenwood monoblock. I just want a little more low end on my stock stereo. I called ford and they could not give a direct answer (they want to sell me their system) as to if it’s bad for the hybrid type system. Do you see any problem with this setup?

      Great video and extremely informative. I'm questioning your statement that, by using the tool that creates the "square crimp", the resulting terminal will not fit into the amp. I assume that the OD of the uncrimped ferrule is larger than the OD of the crimped ferrule, so the crimped ferrule should actually be able to fit into a smaller hole. I do agree with you about the set screw making its own crimp, which will help make it more secure. I plan to purchase a similar kit as what you have, not only for mobile audio installations, but hopefully lots of other projects as well.

      Could I use this for under the hood. Battery -> fuse -> amp. I’m always worried the wire will find it’s way out of the fuse under the hood.

      Same as, all day every day. Especially in for S & Y plan systems. In states pretty much anywhere other then solid core wires ✋

      Good to know though thanks! I have had a bag of tinned 4awg ferules for a long time and I always used them like an uninsulated crimp cap for 8awg wires before I soldered.

      Ive got a quick question can you use the ferrules on OAWG power cable going to a battery positive clamp. I have an audison SBC-41P positive clamp. Will it hold as well as you have shown in your video when connected to an amp? thanks in advance and keep up the great videos!

      Search google there is a company that makes wire lugs that use either bare wire or ferrel, then it could bolted to marine terminal or bolted straight to postless bat.
