Wire connectors for car stereo are used to connect the stereo wires to the car’s electrical system. The most common type of wire connector is the butt connector, which is used to connect two wires together. Other types of wire connectors include the ring terminal, which is used to connect a wire to a metal surface; the spade terminal, which is used to connect a wire to a terminal block; and the bullet connector, which is used to connect a wire to a terminal block or to an electrical device.

All of the pieces were accounted for, including extra in case you need to mount the ground to your car. Luckily I didnt need to mess with that, but it wouldnt have been that much of an extra hassle. The butt connectors were easy to use despite my inexperience. The zip ties were a nice touch. I used electrical tape to secure each connection in addition to the zips. That should hopefully reduce any pull experienced on the connections. The only problem I had with this item is the lack of instructions. It comes with mostly red connectors and a few blue. I know the difference in AWG (one is 16/14 wRead More David
Joining the 12 wires from the new car stereo, to the new wire harness – is , for he layman, probably the most daunting task, and the reason why most people dont try installing their new car stereo, themselves!But after using this wire connecting kit, I would not hesitate to tackle this job again! Using this kit is sure quicker and easier than soldering the wires together and I wouldnt hesitate to buy another one of these connector kits for any future car stereo (head unit= dashboard) installation!. It may also help if you have strong hands to squeeze these connectors onto the (bare) wire ends,Read More Doctor
These are actually really awesome and I recommend getting a pack or two. It is nice because if you mess up you dont have to untangle the wire or cut it shorter. Just cut the tube in the middle and pill the two wires out of each side. I prefer these better then other wire connectors.

Slightly different than last set I bought. Plastic must have been updated to fit newer factory harnesses, but still fits a 2001 Yukon door speaker harness. Nice that it has the female slide terminals to match aftermarket speakers. No guessing about phasing of speakers. 
ItsJustMe
I used these to install door speakers in my work truck. They seemed to be good with a tight fit and easy to use. Within 2 days my speakers started cutting out. After troubleshooting for a hour I found the problem. After replacing these with another brand all is well. 
daWoose
When I bought my replacement speakers for the back doors of my Trailblazer, I didn’t want the hassle of soldering or other time consuming methods to connect the factory wires to the speakers. These fit the bill perfectly, just attach then to the existing GM connectors, and then connect the other end to the speaker posts. Done.

The adapter fit correctly. I had no trouble wiring the new radio. Color for color splicing is all that is needed. If I ever remove the radio and reinstall the OEM radio all I have to do is unplug it. Its an easy way to avoid cutting the OEM wiring. 
Anonymous
Fits like a glove and looks like it came with the car looks and soundsnan ton better! So thank you!! 
Casey C.
Ive replaced 2 radios in my car and some for my friends cars and I always bought a harness for each install. It saves so much time trying to figure out which wire is which while inside the car. And its so much harder to solder the wires while in the car. I always wire the harness to the one that come with the radio and itll make it plug and play.I recommend anybody doing a radio install buy this harness. The time saved is well worth the 10 bucks. Good thing this came free with my radio. Thank you Sonic Electronix!!

This was an easy harness. Color coded correctly and very easy to connect. Good length on wires. I have had cheap ones and this one was quality. It makes it nice when wires are long and easy to splice.

It feels very cheaply made and does not fit properly it is close. But since I have not found any other brands that offer this kit I guess it doesn’t matter. 
Jonathan R.
This connection adapter made the installation process much simpler and easier than otherwise would have been the case. Connections were very straight forward. Including Insulated pinch wire connectors with the adapter would make it even better and easier to use. I recommend this product

Used this connector to adapt a single DIN AM-FM, CD head unit to replace the stock radio in my truck. The stock radio was operative, but did not have a CD player. The truck also has the stock speaker setup, with 2 front and 2 rear rear stereo speakers. All speakers were operational with the original stock radio. The wire connections were made correctly from the replacement unit to the mini connector, with each connection soldered well and insulated with shrink tubing. However, only 1 of the front speakers is operational when the replacement unit is powered. This was not the result I expected. Read More GuitarGuyDIY
Made working with the factory wiring harness so much easier. Didnt have to cut the factory connector to install the new radio, so I can still put the stock one back in if I ever want to sell the vehicle. Brings the old connector color diagram up to modern code so you dont have to pull up a wiring diagram 
Matthew
You cant beat Sonic Electronix when it comes to car audio! They take great care of their customers! This wiring harness along with the dash kit was absolutely FREE with the purchase of my head unit which was purchased here! At $10 each, thats an instant savings of $20!! without having to do anything! Thats the reason ill keep coming back. This kit fit perfectly and worked and looked great along with my new stereo. Came with everything needed to look like a clean, professional installation. Thanks Sonic Electronix!

This adapter plugged into the new radio as advertised. The other end is all pigtails (loose wires). So had to splice all the other connections. You’ll need a lot of patience to match up the correct wires to the ones in your vehicle and will need a means to translate the vehicle wire colors to those on this adapter. Maybe obvious to most folks but thougth I’d warn the newbies. 
HSchoon
Good price for a stereo harness to ease in aftermarket stereo installs. Everything connected just fine, read reviews where others had to shave or remove material from the harness so it could connect. Never had that issue but can see that as these are semi universal and fits multiple models. All the colors were there for my install on a 99 toyota camry le with pocket under stereo. Installed a Pioneer double din dvd player with backup cam. All settings worked, 1st thing i usually do is check Fade/Balance to make sure I wired it correctly. 
ehhhsteve808
This part would have worked fine it’s good quality too but after purchasing it I learned if you have any type of factory amp it must be bypassed. My 05 Tundra oem amp was a Panasonic amp about 10 watts per channel fwiw..lol There is a new Metra amp Bypass harness out for “Non JBL” Tundra stereos with an amp like mine had. The new one has very long wires it’s Metra 70-8121 Amp Bypass Harness kit. My 2005 Access Cab Tundra amp was not in the dash, it’s under the rear seat in storage area under a plastic cover. Double cabs are on back of cab wall behind a cover behind their rear seat. These casesRead More NoTech

Drove a hour and half from to get this part that a “team member” said would fit my 2011 Subaru Impreza and it didn’t fit at all. Definitely need to update the inventory to reflect this so others don’t go through the problems I did. 
Jaguar
sounds great. No trouble. However my issue is with the service and installation. Took an hour longer than estimated, and was left with a car full of trash. I was moving 1500 miles and did not have access to trash service. I had to get cranky to get the guys to take the boxes and the old system out of my car and dispose of them. BTW the installation charge was really high. Last time it was free. For that price they can dump the trash and should have cleaned my car! 
SANDY
I really like these adapters. Only change I would make would be to caution people that the blue wire that is labeled power should be more clearly explained. By the explanation in the instructions, you would think the blue wire should not be hooked up unless you have a power antennae. But, the blue wire should be connected to the spare white wire or blue wire to provide power to antennae amplifier in some cars. I had to tear the stereo out after a complete install to correct this problem.

This wiring harness made installation easy. This was my first stereo installation and I had only 1 wiring issue because of the instructions included. There was an issue with the power antenna wire, but I think the issue was with the original wire. Do not cut wire until you are sure of wiring installation. 
Johnny
This harness was a game changer, it made installation of my radio a breeze. I would recommend this to anyone looking for a good value. 
Sabatino
Wiring adapters let you wire up your radio on a bench, then when it is time to install it in the car you dont have to splice any wires. Also, if you sell the vehicle you can just plug the original radio back in because the original wiring will be intact.

USB was my main reason as was the cost here of $90. Sure, I have Bluetooth in the Iphone 5s but when Im traveling, Bluetooth doesnt charge. Tried many of those FM transmitters which are less then what they should be for quality sound plus you have to tinker with the settings when static comes in. Plus with USB, it charges, plays anything from the phone AND whether it be MP3, Pandora, IHeart, TuneIn, etc…the RDS displays the song title and singers. All while using the steering wheel controls.So this Sony G3100UP was the ticket for my 2005 Camry with factory AM/FM/CD player…not a JBL system Read More Robert
I replaced the factory radio after the CD player stopped working. All I had to do was match the wire colors from this harness to the new radio harness. I did check the radio manual to make sure what function each wire performed. I plugged the factory connectors into the harness. The factory connectors locked into harness. I checked the balance and fade on the speakers and the radio is working correctly. I had no issues with this product. I would recommend this product for ease of installation and cost. Even with the shipping cost added in, it was cheaper than buying it locally if you can wait Read More Jeff
I tried to install a Pioneer stereo without this and quickly realized the amount of headache this would avoid for a mere $6 was worth it. Boy was I right. Easy installation, I was concerned about the wire colors not matching my cars connector so I called and an experienced installer from Scosche told me to go ahead and connect. It worked like a champ. I wouldn’t consider a radio install without a Schosche wire interface. Just buy it would be my advice.

I received this harness when I purchased my new head unit. It was my first time ever installing anything like this so at first it felt over whelming. But Sonic Electronix tutorials and guides made it where even I could install this without any problems! I havent had any problems since and the Tech Support I recieved was excellent! It was almost too easy, where I even contacted customer support to make sure I did it right lol. Highly recommended! Fit my 07 Hyundai Sonata great. 
Elizabeth
Everything tied in perfect for my double din head unit install, save for having to run a separate ground from the unit as I got engine feedback with the pinned one. Likely not this products fault though. 
JAMES
Bought this for my 2011 mustang w/o nav in order to install an aftermarket HU. This does work for part of the install, but if you want switched 12v+ for the HU, youll have to find your own or buy a different wiring harness. It only takes 10min to find a switched positive if youre electrically savvy. Quality is good, and it does what it describes.

They sell this as a direct fit for my 2007 Pontiac Vibe. Sure, if you don’t want to keep the factory amp or subwoofer. After installing I had to call Metra and then after they looked for a few they tell me I don’t retain the sub. They also don’t mention that you have to install an in line converter. When I have time this is coming out and I’ll pin put the factory wiring and get my system back up and running right. Waste of time and money.

Bought it for a 2005 Silverado which it doesnt work with completely. The radio and speakers work but you lose the door chime and a few other small features I never really cared for anyway. For me, it was a perfect purchase.

This harness came with pre-stripped ends of the wires which saved me some time when hooking up my car radio. The wires were colored appropriately so that there was no doubt when connecting them to the radio’s harness. The radio is working perfectly.

This was the right part for my 2000 Grand Marquis. The price was best, especially with free shipping. Soldered the wires together matching the color code off the package to the aftermarket radios color code. Works great.

Do not attempt to install a radio without a harness adapter. With this type of adapter you can do all of your wiring on the bench (or the couch) and then just plug it into the cars original harness. Safe, easy and fast. The 70-1771 works in Ford Crown Vics that are PIs, which do not use the 24 pin harness used by standard Vics. Sonic offers the best service, variety, shipping and price of these wiring harness adapters. The use of this harness will allow you to reinstall the original radio at a later date or if you need to reinstall if the new radio goes in for repairs. Even if you never need oRead More Paul

My radio is working well after having it mounted by Car Toys. They did a great job even though they forgot to call me when they finished the job. They were very knowledgeable and polite.

Why wouldn t you get some of these. They have the correct size terminals for the speakers. You don t have to cut anything. These are an easy decision. Everyone should use them.

I needed adapters for the rear doors of my Legacy Brighton wagon, which did not have speakers installed but did have factory wiring for them. These adapters fit right on the factory plugs.

These adapters work great for adapting aftermaket front speakers to the stock wiring in 02-07 Imprezas. The small tab on the stock wiring plug needs to be removed and then this is plug and play.

This is a good solid connector. It was recommended for the 92 S-10. I ordered it as recommended. Soldered it to the harness of the aftermarket receiver. No Go! I found out after pulling the stock receiver. 
Tedro
I purchased this from this site because it said it was an exact fit for my 02 Pontiac grand am. It was not. Not only are the plugs completely different but that year vehicle needs a Data Bus Interface module. I went with PAC for anyone struggling with the same issue. 
Jordan
This made the install so much easier! This is a must have. Everything is labeled and the instructions/diagrams were very informative. No need to struggle with cutting,crimping,soldering, or heat shrinking in the vehicle. You can do everything comfortably at a table or workbench, then plug and play. Great product!

This the harness you need to connect an aftermarket radio to the factory Bose amplifier system. In fact, if you plan to use the Metra-Axxess ASWC-1 to connect to your steering wheel controls, you will need a second one, as that installation requires two more pins. With a pin removal tool, you can remove two pins from the spare and insert them into 1N and 1P, which are blank when you buy the harness. The Metra harness was shipped promptly and reached me promptly in California. I appreciate the very competitive price, because as mentioned, I needed a spare for parts. I have attached a pin diagraRead More jcheeverloophole-esq
This made wiring a new stereo into my 2013 Mazda MX-5 Miata very simple and I did not have to cut any of the existing wires of my car. Just used butt connectors to connect from this harness to the new stereo and then plug into original vehicle harness. My only complaint is that this harness did not have the steering wheel control wires (signal + ground) needed to get the steering wheel controls to work. Luckily the harness had a few wires that I did not need nor would use (stock Amp etc.) so I pulled them out and relocated them to where I needed them. It worked beautifully. I am one happy custRead More sonicelectronix.com
Clearly labeled. If you have any idea what the wires for a head unit do, you should be good to go. I used this to connect an aftermarket head unit and also do I could put an amp in between the unit and the wiring harness utilizing the Hi inputs on the amp. Worked great. Dont attempt if youre clueless.

This kit is good, but its only good for main wires: power+, battery, power antenna, remote turn on, dimmer. The speaker wires will not work! Rca cables wont either, you will need to run your 8 speaker wires from your media player or a cd player to your trunk and splice into your factory amplifier speaker output wires in order for all your speakers to work including door speakers and rear deck in your sc300/400. I rate this kit 4 stars because I didnt have to cut the dash wiring!But did buy 50ft roll of wires and its sounds awesome with my JL Audio10 subwoofer and alpine that I got from sonic tRead More Garen
After the correct harness kit arrived, installation is a breeze. The unit works like I want. Really like the USB port dubbed as USB charger. The remote control is very useful changing the volume without leaving your eyes off the road. The only negative is the light of this unit is red, a bright red like something is burning hot. Wish Sony has the option to change it to soft blue, green or yellow. 
DYI
Perfect if new deck has 6 RCA outputs. 4 outputs for L/R Front & Back Speakers. If deck only has RCA subwoofer output, then user needs to use a female RCA, strip the ends, and solder or crimp to speaker wires on the deck harness. That’s the route we did. You definitely need this if not planning on removing the factory amp.

My mother’s Old Lincoln’s stereo gave up the ghost and fixing it in Natchez MS was extremely expensive due to a lack of choice. Enter Best Buy.

Researched the harness needed for my 2013 Ford F150 Truck. According to the compatibility information listed with this product, I purchased it according to this information. At the time of the installation of my audio player, purchased for my vehicle, I was informed by the Best Buy Installer, that the harness I supplied was incorrect.. He looked up the information on the store computer, and showed me the description of the harness needed to start the installation. He asked me, if I would be willing to go to a local mobile audio dealer/installer, that he suggested. He also indicated, the dealerRead More dwflpo
I had to do a lot of reading and youtube vids to make sure I was doing this correctly. The install manual and harness packaging color guide aren’t enough if you’re a novice installer like me–like this was my first attempt ever. However, with extra research, I got it in and it works beautifully–2004 Ford Expedition Eddie Bauer and a Pioneer AVH-1300NEX. The install was actually fairly quick. Most of my time was in the research beforehand. I also made all my connections in the house with good light and plenty of room to work.

Works great. Connected the harness to my indash harness first. Unplugged The factory harness from the stereo and plugged it directly to the harness. All Plug-and-play did not have to even disconnect a car battery. Even has illumination wire.

I was very careful when selecting a wire harness from the auto parts store, they even have a nice booklet on the back that tells you every single type of vehicle that it is supposed to work for. My vehicle, a 2011 crown Victoria is listed at the very top, however these are hugely incredibly different connections. The one from metra is way wider and does not fit any of the pins that came factory with my crown Victoria. What a waste of time and I was excited to hear my new system. 
Just want good audio
So again, I thought I would be frugal and go with the recommended wiring harness for the radio in my daily driver. Well, that was a fail being that this recommended harness doesn’t include a Nav connection and also does not have the steering wheel control interface. This is fine if you’re working with a vehicle from the early 2000s that doesn’t have those features. Oh and I almost forgot to mention, the radio always resets to factory settings whenever the vehicle is shut down. It’s not my car battery either.

Best Wire Connectors For Car Stereo Buying Guides

What are wire connectors for car stereo?

Wire connectors for car stereo are used to connect the stereo to the car’s electrical system.

How do they work?

Wire connectors for car stereo systems allow two or more wires to be connected together. They come in a variety of shapes and sizes, and are made from a variety of materials, including plastic, metal, and rubber. Some wire connectors are designed for specific applications, such as connecting the positive and negative wires of a car stereo system, while others can be used for a variety of applications.

What are the benefits of using them?

One of the benefits of using wire connectors for car stereo is that they help to keep the wires organized and tidy. This can make it easier to install the stereo, and to make sure that the wires are not going to get tangled or knotted. Additionally, wire connectors can help to protect the wires from damage, and can prolong the life of the stereo.

How do you choose the right wire connector for your car stereo?

There are a few things to consider when choosing the right connector for your car stereo. The first is the type of stereo system you have. The second is the size of the wire you need to connect. The third is the type of car you have.

The type of stereo system you have will determine the size and type of connector you need. If you have a factory stereo, you will need a different connector than if you have an aftermarket stereo. The size of the wire you need to connect will also determine the type of connector you need. The third factor to consider is the type of car you have. If you have a newer car, you may need a different connector than if you have an older car.

To sum it up, you need to consider the type of stereo system you have, the size of the wire you need to connect, and the type of car you have when choosing the right connector for your car stereo.

What are the different types of wire connectors for car stereo?

The most common types of wire connectors for car stereo systems are butt connectors, ring terminals, and spade terminals. Butt connectors are used to connect two wires together end-to-end, and are crimped onto the wires using a special tool. Ring terminals are used to connect a wire to a metal post or screw, and are also crimped onto the wire using a special tool. Spade terminals are used to connect a wire to a metal post or screw, but unlike ring terminals, they do not need to be crimped onto the wire; they simply slide onto the post or screw and are held in place by a small metal tab.

How do you install wire connectors for car stereo?

To install wire connectors for a car stereo, you will need a wire stripper, a wire cutter, and a crimping tool. First, strip the insulation off of the end of the wire using the wire stripper. Next, cut the wire to the desired length using the wire cutter. Finally, use the crimping tool to connect the wire to the stereo.

What are the troubleshooting tips for wire connectors for car stereo?

There are a few troubleshooting tips to keep in mind when working with wire connectors for a car stereo system. First, make sure that the wires are properly stripped and that the connectors are properly crimped. Second, make sure that the wire connectors are compatible with the stereo system. Third, make sure that the wire connectors are properly sealed.

How do you care for wire connectors for car stereo?

To properly care for your wire connectors for your car stereo, make sure to regularly clean them with a damp cloth and mild soap. Once every few months, you should also use a toothbrush to gently scrub any dirt or build-up off of the connector’s teeth. In addition, always make sure to dry the connectors completely before storing them away.

Conclusion

There are many different types of wire connectors for car stereos, and the best one to use depends on the specific car stereo and the wires that need to be connected. In general, the best type of connector to use is a soldered connection, which will create a permanent and strong connection between the wires. Another option is to use a crimp connector, which is also a strong connection but can be easier to disconnect if needed.
