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!

      One thing to remember when using ferrules: ferrules are intended to let you connect stranded wires to a terminal intended for solid wire. A clamp terminal designed for stranded wire will not mess up of defray you wire. These are usually cage clamps, the kind that have a small metal box that shrinks down when you tighten the screw. The other type is just a bare screw coming down on your wire, those should either have a solid wire installed or stranded wire with a ferrule fitted. The amp in this video does look like they are all bare screw type terminals.

      Do the smaller ferrules like 12Ga insert all the way into the back of the amp's terminal? Long enough?

      So today I discovered that not one electrical supply or car audio storefront (or distribution warehouse) in the entire greater Seattle area carries these thin-walled, copper ferrules. Kinda nuts that you have to order these, especially in such an industrialized metropolis such as Seattle.

      It's also flexible due to the way it's made. Car audio wire is high voltage, low amperage (tons of tiny strands), as home electrical wire is high amperage low voltage, hence the very large strands but few in number.

      Ok i have a kenwood unit with sub out and sub bass control first i had a crunch powerzone 1100.2 the old black one i could bump with sub level in the negative range same head unit but now I have a Audiopipe gd 3001 and i have to have the base level in the plus on the head unit what up with that

      Awesome. Always look forward to stepping up my audio game without having to do some backyard hack. I know nothing, absolutely zero of audio. Question arise like, are there subs a amp can’t handle, what a good size ground, what method have to done to create a ground without making a mess, what gauge wire works best with certain size speakers. I just want clear loud music. Not much of bass or tremble but a normal amount is good. Not a subwoofer kind of guy. More race track. But I will definitely navigate through your channel. Thanks

      yes it's a hard concept to grasp for some people that wire ferrules are just to hold the strands in place nothing more...... it is plain to see what the set screw does and how the ferrule works.

      Could you fill the wire with solder instead of using a ferrule? In theory, wouldn't it be accomplishing the same thing? Sort of grouping the strands together and giving the amp set screw something to bite into effectively?

      CarAudioFabrication In reply to Chase Burnham

      Solder doesn't easily bend and form to the shape of the terminal and screw. Not a good idea. The ferrules are cheap, no reason not to do them

      Could you use these for speaker wire to wire subs in there push terminals for wiring 2 subs together ?

      This seems a lot easier than using solder on the ends of the wire to hold the strands together.

      @Eliseo Bundoc Good call. I'm always looking for a better way to terminate. You can spend so much on cable and your equipment and then it comes down to terminating the best way possible so you're not taking away from anything. ya know

      Eliseo Bundoc In reply to Paul Weston

      Paul Weston I feel ferrules have a place for larger diameter wire that I normally don’t solder. For smaller wire such as the remote wire, etc. that you mentioned, I typically solder completely (not just the end) so that I don’t have to worry about damaging strands.

      Paul Weston In reply to Paul Weston

      @Eliseo Bundoc True. I was thinking more along the lines of justifying getting a square ferrule crimper. iMo I don't think there is any need for it in car audio. Audison does use em for high level speaker inputs, or for +/-/rem inputs on non amp models. Mark was saying a lot of car audio companies are starting to use these but I really haven't seen any at all beside Audiocontrol and still its only for the low level stuff like my epicenter. Just thinking why he'd promote an item in such a way as to tell his viewers that they should get one.

      just MELT a little bit of soldier wire on the tip of the wire to make it hard and THEN insert the wire into the hole and tight the screw.

      Solder doesn't compress and take the shape of the terminal.
