Wire Ferrules - BEST Amp Connection - WHEN TO CRIMP!?

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? Let's find out!

[@markdipietro7493]

Thanks for the sourcing. Very helpful.

[@Stormmaniac]

I just got a system but would like the best 4 gauge wire I can find, I'm new to this stuff and had the system installed but feel I should use a better cable

[@NickBuenoo]

Where is the Colored plastic part of the ferrule shown in use ??

[@kevin409galv]

WOW! I just installed an amp in my boat and then saw this video. I really hated the way the amps set screws damaged the wires. I had a defective amp and ended up removing and reinstalling many times and the wire kept getting damaged. I pulled the amp one more time and installed ferrules on all power and speaker wires. I never knew ferrules existed before this. Such a clean and professional look.. Thank you!!

[@mitsibeaver]

Just ordered my 4 gauge ferrules, gotta do things properly now we know how to. 👍🏼

[@100AcreWoodDesigns]

This video single handedly upped my game. My install looks so clean it's scary! Beautiful connections! Thank you so much. 2 DB55s, 2 USS 8", 6 6.5" DS18 Pros, 4 DS18 Tweeters, 2 3.6" Kenwood, 2 Infiniti 6x9s, 2 JBL 6x9s, 2 8" K9s in a sealed box. Thanks again!

[@CragonThe]

Great video! Some folks in the comments recommended tinning the wires. DON'T DO THIS! That would be unnecessary and indeed a bad thing. A good crimp connection is gas tight (sometimes referred to as a "cold weld"). There's nothing to gain in using solder. Tinning the cable instead of crimping would also be bad practice. "the reason this is so is that the differing thermal expansion rates of copper and solder cause a problem. The solder in the tinned wire end expands more than the copper (brass) terminal and a big peg in small hole causes the softer metal to yield (it gets softer with increasing heat as well). When the temperature drops later the parts contract again but now the tinned wire end is smaller than it was and causes a bad connection." (Wire termination for screw terminals. (2014, December 29). RepRap)

[@gabrielM1111]

Not if you twist the stranded hard and go heavy with the solder. Then file the end down to make a perfect hard cylinder with copper exposed from filing. I'm using number for so there is room for expansion inside the poor and the screw I tighten it every two weeks and it's embedded in the end. My way gives a direct contact between the wire and the brass port. For extra measure I wrap electric tape around the cable ends where they go into the ports

[@poipoi300]

Gas tight, you're funny.

[@philipiano001]

Thermal fatigue.

[@chrisrichards1446]

Well done for spreading the word about ferrules/boot lace crimps! I have been using them for years for electrical / electronic work . The one thing I will say is it didn't look like you had stripped the wire quite enough , the wire needs to reach the end of the ferrule as demonstrated on the first power cable otherwise when you screw down the terminal it only catches the ferrule and not the wire , after a couple of wiggle the end off the ferrule will break off!

[@xxjcxx89xx36]

I actually just did my first install and I used ferrules on all my wires 1/0, 4, 14, 16, and 18 awg. I had all insulated ferrules and I would slide on a heat shrink wrap then the ferrule then crimp the ferrule on the side closest to the insulation with pliers (either needle nose or a fatter grip for the big wires) then slide the heat shrink back up just over the insulation and heat it up for a tight fit. This gave a clean result for me and the wires didn't have any issues going into any of the holes.

[@vermili0138]

Mark, I have to say, these ferrules are great! I tried them recently to install an extra battery for a friend and the cables look neat, coupled with a heat shield under the hood they look fantastic! Also, they hold on the strands so well it's hard to pull the strands out once they are crimped.

[@jagtech06]

You posted this video right after I ordered a set of ferules for my 5 channel amp, validating my decision. After finishing the install yesterday, I must say, I’m never going back! Ferules for the win!!!

[@cmart9240]

You are quickly becoming one of my favorite audo installers. You and steve meade are so informational, it's great. I still don't understand the concept of setting gains/EQ and finding distortion/clipping, but I'm just gonna have to sit down with some SMD tools and read the manuals I guess before starting my next build.

[@GTILOUD]

Nah bruh waste of money on that bs oscilloscope is all you need a dmm with oscilloscope

[@CrazyCranker]

Even six years later this video is valuable! I never even knew about wire ferrules. Learn something new every day. :)

[@Eebling1]

I have been recently watching a lot of videos on car audio, upgrading the factory sound in my 22' Telluride from the pretty unimpressive system it came with. This video was probably the best one to just make the install look cleaner. I ended up ordering the kit through the link and it is so much nicer having those little metal end caps crimped onto the wires than constantly re twisting the bare copper ends anytime I remove a wire to check something and have to get it back into the LOC or amp.!

[@WindOfTheWisp_Janine]

Thanks for the excellent video! Love ferrules & am surprised that more folks in the US don't know about their uses & how essential they are. Have been using them recently on some projects including my outside AC condenser unit. In other countries, but not in the US, in 120V/220V applications, it is against code to connect stranded wire to screw lug terminals, as it will result in splaying of the strands resulting in a poor connection (wires mashed down & not all strands making a good connection). I installed a SureSwitch contactor to replace my standard contactor in my AC unit. It has screw lug terminals & I used ferrules to make the connections. Even though the connections were round, I still believe that there is better contact than using bare strands. As others have pointed out, there are crimpers that make a hex crimp instead of a square crimp to better fit in round terminals.

[@PANTYEATR1]

this is a real car Audio education. Mark you have come a long way bro 💪

[@bravomike09]

Outstanding work! I've been an electrician for 40 years in many different forms. I'm an FAA A&P mechanic and hold an FCC GROL to service avionics. I've designing and installed home and automotive security systems. I've worked commercial and residential electrical work. Both high and low voltage systems. I've repaired autopilots inflight. Several times. And I'm happy to say I've learned several new techniques here. Really cool.... Thank you!

[@ItalianStallionLouie]

You always take things to the ultimate level, when I think I’ve done a good job you show me excellent new ways all the time.

[@noahzempel]

Did this for my current build because of your videos....ssssoooo glad I did. It has made dealing with wire so much better. Thanks for the videos.

[@markust.8368]

Thank you for all your videos! This one helped me a lot to make decent connections to my amps. As you know, we all are not professionals and your videos gives us just the info we need. So, thanks again and keep doing the good job there!!

[@joshcosta423]

Still my favorite wiring video you have out. I REALLY need to get that crimper and Ferrules

[@scorpven]

This is a great idea, easy and simple. I have always used solder to tinned the wire ends with my handy butane soldering iron for car installs, just had to be careful not to make them too fat.

[@bradleysmith681]

Indeed. Tin the stripped area and insert under the set screw. Ferrules are a little cleaner.

[@huntergowder861]

I thought I knew a good bit about car audio... but every turn in this video I learned something completely new 🤘🏽👌🏽

[@Laborchet]

And here I was looking for a crimp tool that would do 1/0 and 4awg wires… little did I know, I could just “crimp” them in the very terminal of the amp for a clean and round result!! Here we go let’s install!

[@phxedcwo]

Ordered and used a crimper set after watching this video, works great. I think of all the years of not having this, what a waste. Thanks for your videos.

[@benjaminreinhardt259]

Mind blown! I hadn't even considered pin ferrules on speaker wiring. I use them on electronics projects and will start using them on my speaker wiring. Much easier than soldering the ends. Thanks!

[@naptownbucks]

Thanks! You save my life with this. Bought a Rockford marine amp and I was racking my brain trying to figure out how to get that 2 guage wire to fit in those little slots on the amp block! Thank you so much for posting the link as well!

[@craigshea2930]

Thanks Mark, @CarAudioFabrication, very helpful content, as I was wondering whether you did crimp those 4 AWG wire ferrules and this answered the question completely. Very good content!

[@Es0ter1ca]

Hey mark, I strongly recommend using a light around of copper antiseize on the bigger amplifier ferrules. Sometimes the connections can seize inside the bore after the set screw forces the O.D. Of the ferrule out and the copper will prevent that and promote conductivity.

[@kevinfoster2308]

Genius

[@bradleysmith681]

Thanks for suggesting the ferrules. They offer a professional look and give a low resistance connection. Also, there are ferrules that crimp the barrel, behind the contact that fits under the set screw. This style keeps the contact round, doesn't flatten it out. I don't know, however, if they are made for wire that size. You are definitely a pro!! Thanks!

[@nathanyoung5213]

Love these videos. Setting up two car amps and want a nice clean install. I remembered this video and came back to watch what was used to terminate the wires. Wire Ferrules. Putting a Amizon order in tonight.

[@scottwa]

I discovered these a couple of years ago and used them on my last stereo install. Did it old school and these helped make the connections much more secure and cleaner looking. I enjoy Steve Mead's videos and am surprised I've never seen him use them, with his overkill wiring, you'd think he'd like a good connection at his wiring blocks.

[@ryanwilson5936]

Subbed so hard it shook my windows! Seriously though, just subbed because you’ve taught me a lot in last 2 days. I really enjoy your delivery. I’m getting ready to do a full install in my 2014 equinox and your dad’s series of videos are really helping me out with what I’m about to dive in to. Thanks my man!

[@bradwinter7028]

Thanks for this video, I’ve had many cars and wired amps/subs over the years on my own. I have never realized these existed until this video though lol. It’s the simple satisfying things like these I love. I love a clean installation and always hated the frayed wiring. Just ordered some.

[@dfhjgddhh]

My favorite thing is the plebs on Reddit suggesting ferrules cause bad connections. It's incredible the information people are willing to spread without knowing much.

[@ProperMethodz]

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

[@DR0CK]

Shit. Was going to say exactly that lol

[@hannahranga]

Very common in any kind of industrial power supply. They're real nice especially as you don't need any special tools but you still have a connector instead of lots of individual terminals

[@NemoPropaganda]

Or euroblock but same thing.

[@narmale]

europe has been using them for years, they are great in PLC's and MCC's

[@premitive1]

The word "those" about a video with several different things mentioned, is confusing.

[@versus023]

Dont know why, but seeing your ''wire job'' is soooo satisfaying for me! haha. theyre so clean!

[@itsagueybana]

Wow - thanks for this video! I'm about to set up a system this weekend and this is going to make it a hell of a lot easier!

[@brianbarajas2948]

3:50 thanks man. This was a slight nuance that I didn't understand in your install video. This makes sense after you explain it, i thought it needed crimping.

[@bradquinn4161]

The crimpers are also made to make a hex shape rather than a square. The work better on the round "sockets'" (or holes) instead of using the lug to crimp the ferrules.

[@toni0034]

when you crimp those wires, make sure the wire pokes out of the ferrule, then cut the end (only a little bit!) with side cutters. that's what I was taught in school to ensure good connection. edit: typo.

[@vartsn]

yes, this is the correct way

[@eduardocortez9838]

Hermoso video amigo

[@Foof50]

Side cutters? You mean diagonal cutters? Flush cut or semi flush cut?

[@toni0034]

Foof50 well, translated straight from my language, they are side cutters. those really small ones that could be used to cut your nails lol.

[@erico.8391]

Same thing.

[@yuhboireycoon3727]

I like that you used the word "thus" very nice vocab

[@robertmisciagna185]

I broke down and picked one up, absolutely love it! Very shot learning curve!

[@SupraBdub]

Been looking for one of these kits, not doing pro install currently but always prefer proper wire termination and connectors. Good to have in the toolbox. Thanks

[@itsbmd6225]

I used "1/0 to 1/0 Input Reducers" in my install for all of my 0 gauge. They're similar, just slide the wire in, tighten down the allen screw and add heatshrink. I should get some ferrules for speaker sire, remote wire and such but I think they're more necessary on larger wires as they are usually harder to fit into amps as most don't have true 0 gauge inputs.

[@richk9033]

I used those ferrules for the same type of Phoenix connectors on A/V controllers. So when I installed a new system in my truck, I used them for the remote wire and monoblock for my sub. Need to find a couple for the 4 Guage power and ground wires.

[@suprola7961]

Hey Mark, there’s a round crimping tool out now. Well, it’s more of a 6 sided thing, but it’s not square.

[@MrBroly10000]

For amp power and any screw only type connections, the ferules do come handy. For the square type I tin the end of the wire and that makes for a strong solid connection that I can insert emove multiple times.

[@premitive1]

solder can crack, and it doesn't penetrate between the wires.

[@PedallingwithPaul]

I have not had a chance to really use these yet but I did buy some because of this video and I am 99% sure I am going to be very happy I did

You can also use removable banna plugs for speaker wire connections depending on the wire and terminal gauge on amplifier. I use banna plugs on my 2ch amplifier to feed my full range speakers.

[@bigcountry55]

i actually use copper tubing for this purpose, been doing it for years but glad to see someone finally put the idea to use

I actually like your idea more. The idea of using tin plated copper just doesn't make sense to me when I'm spending so much money on a 100% pure copper wiring

Great video just what I needed on a rewire. I have a rewiring nightmare

[@scottnelson3031]

On the bigger gage wire turn the ferrules around and crimp it and cut the plastic off of it and it makes it a cleaner look when it doesn’t fit around the installation.

[@premitive1]

HOW to crimp the bigger gauge wire is the question. In the video he uses the set screw in the terminal block. In that case, he'd have to cut off the plastic before crimping it.

[@PeteyG708]

Great video. I need to add these to the wires going to my Pioneer Amp in my truck.

[@thejeff1974w]

Dude...your a mind reader! I just ordered some of these for my subwoofers. Going to order some for my amps soon!

[@MrMousy602]

I was able to crimp the ferrules by crimping on the very end of the ferrule allowing me to still get a tight secure fit and also allow me to plug it into my amp.

[@Phil00661]

I work on refrigerated trailers and some of the electric models are wired up for 460 volts with thicker gauge wires and I was wondering how you crimped the bigger gauge wire, thanks for explaining everything

[@incredifunk]

For something as large as the wiring you'll need for that job you will need to approach a hydraulic crimper. Cost around $80-$100 but definitely worth the cost for bigger jobs such as yours. Especially if it's something you're gonna use frequently

[@westcoast510]

[@shanerivers8141]

👏Been stressing about buying a crimper for 50$ to only use on 6 ferrules. I have set screws, great idea "crimping" with setscrew forming ferrules

[@eddyherrera6326]

Same here!

[@kyleburns2758]

Just a quick little tip: twisting the strands increases its diameter.. use either to make up slight differences in diameter between terminals and conductor, or to fit the largest possible cable into the tightest terminal by straightening the strands

[@frankbush8368]

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.

[@eddyherrera6326]

I found mine at home depot... just sayin

[@CliffdropChad]

Seattle sucks

[@premitive1]

I'm surprised no electrical supplies had this. it's very common in electrical installations.

[@larrygaines7462]

I soldier them on,or soldier the twisted strands. After you crimp with Ferrell you disconnect and soldier it ,perfectionist, use torch for big gauge wires . Careful with copper coated aluminum wire. Like your post!

[@TheAviation101]

The included ferrules are fine, you can easily cut off the insulation and use heatshrink for thick insulation wires

[@johnaranjo6354]

I work at a wiring harness facility and we have a ferulle crimper with a rounded bottem theres one that does the 20 to 20 gauge sizes and one for 12 to 18

[@johnaranjo6354]

I bet theres on out there for 4 gauge too

[@bryandiel6773]

Even home audio can benefit from crimping ferrules to speaker wires for regular spring loaded hold down terminals. I try to get speakers with binder posts like my Polk bi-amp monitors, but my Yamaha surround and Dayton B652's have the spring loaded pin or ferrule connections. Ferrules would have helped along my set up, rather than waiting for my Nakamichi pin connectors to arrive. I will be using your source for cables. Some connections on amps can use spade connectors as well. old school installs always used spade, or ring terminals or soldered wire.

[@DaleLClay]

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!

[@joshkellis6499]

Great videos. Saving them All. Thank you ! Sadly, this is my first time using ferrules. Quick questions ...... Have you ever broke a plastic terminal block on and amp with 4g wire + ferrule, using the method of screwing it down to crimp ? That's what I am a bit worried about, and am having a hard time finding a crimper that will do 4g. And I hope not to have to pay a lot for it. Lol. I plan on using 8g, 4g, and 1/0g, but the 1/0 uses metal terminal blocks, so not that worried about breakage. And the 8g crimpers I can get but have look closely at specs before buying. Alot don't do 8g. Any suggestions on the 4g crimpers or just screw down? Thanks.
