Most factory radios are not equipped with a dedicated “AUX” jack, however it may be equipped with a CD Changer or Satellite Radio port. Auxiliary input adapters are passive devices that convert the CD Changer or Satellite radio port into an “AUX” input. Auxiliary Input Adapters are limited to audio playback. They will not control, charge or display text on the radio screen. Use an auxiliary input adapter to play your iPod, Mp3 player, SmartPhone, DVD Player, Satellite Radio and other audio devices on the factory radio.

Installing an Aux-In Port is an Easy DIY Task On Every Car

There is lots to love about cars from the 1980’s and 90’s. One thing that is hard to love is the audio technology manufacturers used during the time period. As the battle for market supremacy raged between cassette tapes and CDs, companies tried to meet consumer demands with some truly funky head units. Today, both tapes and CDs have gone the way of the dodo, and new options for music offer far better audio quality and portability.

Collector and enthusiast preferences have changed in recent years. These days, cars from the 1980’s and 90’s are starting to increase in value, and buyers who were too young or too poor to buy what they wanted when these cars were showroom new are finding good condition cars at reasonable prices.

Adding Modern Functionality to Any Car

Have you seen the value of a 1993 Ford Mustang Cobra recently? How about a 1991 Acura Integra Type R? Original, high quality cars have shot up in value in recent years as interest by enthusiasts and collectors has grown.

Cars from this era are a blast to drive, but cutting up the dash to install an aftermarket stereo that offers modern playability is going to tank the resale value. A collector is not going to want to buy a car that has been cut up and modified, no matter how cool the stereo installed in the car is. So, if you are not going to add a modern head unit, how can you play MP3’s or stream music from your smartphone?

Adding an Aux-in port will let you play music from an MP3 player, your smartphone, or whatever digital device you like to use that connects with a 3.5mm headphone-type jack.

Installing an aux-in port is a simple job the average do-it-yourself home mechanic can accomplish with professional looking results in an afternoon. There are many different ways to add aux-in functionality to any car, truck, boat, or whatever else you drive. Even motorcycles can be set up with aux-in playability.

Options Abound

First things first, identify the options you will have for your particular stereo. If your stereo has RCA input ports on the back, you can simply purchase an adapter cable that will plug into the RCA port and your music playing device through a 3.5mm male cable.

Many cars came with ports for CD changers. Adapters are available for many popular models that allow you to simply plug into the CD changer port and add an Aux-in terminal. It is worth taking a minute to search the internet for your particular year, make, and model of car to learn about possible options. Many popular brands have adapters available to work specifically with factory-installed radios. These can be more expensive than doing it yourself, but offer convenience and a clean installation.

Things to Look For on Your Head Unit

If your car or truck has an Aux-in port but it is in a dumb location, or if you just want to add one in a different part of the car, it’s a very simple operation. Remove the port from the dash, or wherever it is located, then cut and splice an Aux-in cord into place, safely routing it to where you want to add a port, and install the new port in a smart place.

Waterproof aux-in housings can be used to install a port on a boat or on the outside of a vehicle, like in the bed of a truck so you can blast your tunes at the next tailgate party before the big game without opening the doors.

If your stereo does not have RCA ports or CD changer controls, you can wire them into the existing stereo. This will require a little bit of knowledge and skill. You will have to remove the radio from your car and disassemble it to make the necessary changes.

Aux-In Port for Mobile Tunes

Auxiliary input ports, called aux-in for short, first appeared in the 1980’s to allow consumers to play tapes and CD’s from a walkman or discman-type player through the car stereo. Once head units started having CD players, many factory head units stopped including the aux-in port. MP3 players had yet to hit the scene, so there was simply no need for the redundant port.

Aux-in ports deliver near CD-quality sound, unlike the cassette or disc adapters that are notoriously bad sounding and do not last long. A device called an FM Modulator can be used to play music from an MP3 player, but modulators have a bad reputation for poor quality sound and can be expensive. They also will not work well without a strong FM signal.

Getting To Work


You should know how to solder and use a Multimeter.


Get the best quality repair manual for your car that you can find.

These items can usually be purchased at electronics supply stores in your home town or online from vendors such as

  • Soldering iron and solder
  • Volt/Ohm Multimeter
  • Sockets, screwdrivers, and pliers
  • 3.5mm Aux port with two normally-closed shunts
  • Wire cutters and strippers
  • A Mono-to-Stereo adapter if your old head unit plays only one channel.
  • Electrical tape for securing wires
  • Wire, 2-3 feet

A method of mounting the jack, like drilling a hole somewhere inconspicuous. Many ports are surface-mountable.

AM and AM/FM Radios

The original head units that featured AM and AM/FM are becoming more rare and valuable to collectors, so don’t throw them out. It is easy to add an aux-in port to these stereos.

Get the best quality service and repair manual available for your car. Try to find the workshop manual issued for professional mechanics, as these manuals provide the best, most accurate information.

Before working on any part of any vehicles electrical system, disconnect the negative battery terminal. Safety first. No one wants to get electrocuted and setting your car on fire probably isn’t what you are trying to do. And it’s no fun finding a fuse that you blew when you short something out on accident.

Disassemble Your Dash

You will need to remove the stereo from the car and open the case, exposing the innards of the head unit. Use a high quality service manual for your vehicle that provides instructions on how to remove the radio correctly.

You will find wires running from the tuning knobs or buttons to a cylindrical part mounted to the computer board. This component is called a potentiometer, or pot for short. It is a rotary switch that allows multiple functions in a compact space.

You will need to identify which wires run to the volume control portion of the pot. A wiring schematic is helpful if you have one. Otherwise, with the radio sitting upright, the wire on the bottom terminal is typically the input, the middle terminal is the output, and the top one is the ground terminal.

Prepare the Head Unit for Modern Convenience

You can unsolder the input wire from the pot at this point. Most head units will have a light blue input wire. This wire will be connected to the Aux-in jack and a new lead wire will be run to the pot.

Using the multimeter or a manufacturer schematic, identify the function of the pins on the Aux-in port.

Identify where you want to install the jack. Typically, near the radio is preferred, but I like to put mine in the glovebox or in an ashtray. I think it keeps it clean and doesn’t take away from the factory appearance.

Make Good Connections

Now, it is just a matter of hooking the wires up correctly. Easy. Get your soldering gun ready!

Solder a jumper wire from the input on the pot to the terminal that gets power when a 3.5mm plug is connected to the circuit.

Solder a jumper wire from the ground terminal on the pot to the ground terminal on the Aux-in port. You do not need to remove the existing ground wire.

Solder a jumper wire from the old input wire to the remaining terminal on the Aux-in port.


Now, all that is left is to reassemble your radio, route the wires safely, install the jack, and reconnect the battery.

With the car on, plugging a 3.5mm cable from an MP3 player or smartphone into the port will allow playback through the factory speakers and volume control will function like original. If the head unit plays music in mono, you will need to plug a mono-to-stereo adapter in to get good quality playback.

When the plug is removed, the radio will play normally.

The process may sound intimidating, but the results are very rewarding. If you take your time and follow the steps correctly, installing an Aux-in port in your car is a straight-forward project you can complete yourself.

Morel Högtalare – Car speakers, subwoofers and loudspeakers Morel

Wireless speaker review from Morel.

The new Bluetooth speaker Morel Högtalare has attracted a lot of attention from users.

At 12.9 inches square and 6.7 inches deep, the Högtalare fits perfectly into one of your Kallax cubes. The system is available in five colors (two on white) to give you a stylistic match (at least on the front of the speaker, which is all you’ll see if installed in an Ikea unit).

The Högtalare – Swedish for “speaker” of course – consists of one 6″ double magnet woofer and two 1″ dome tweeters with three 50W per channel amplifiers. This is a single-chamber stereo system in which one tweeter processes the left channel and the second reproduces the right channel). The claimed frequency range is from 36 Hz to 20,000 Hz.


Högtalare is primarily a Bluetooth speaker, with Bluetooth version 4.2 supporting the Qualcomm aptX codec providing the primary connectivity. If you have two Högtalare speakers, they can be configured with Qualcomm’s TrueWireless Stereo (TWS) technology to have each play only the left or only the right channel, giving you a more traditional stereo sound design and probably a better option for larger spaces (since I received only one block, I was not able to test the performance of the TWS Högtalare).

If Bluetooth is not available, you will find an auxiliary jack and a Wi-Fi enabled USB port where you can connect your Chromecast audio device or similar device and connect the Högtalare directly to your Wi-Fi network.

In addition to the switch on the back, which allows you to switch between manual and automatic activation, all equipment controls are located on the front panel and hidden under the speaker grille. These include the power button, volume controls, input selector, and Bluetooth pairing button. I have connected the system to different devices and have never experienced any minor hiccups.

In terms of performance, Högtalare gave me outstanding results. I was skeptical that placing the left and right tweeters one foot apart could give any semblance of a true stereo experience, but I was happy I was wrong. Yes, it’s clear that even in a small room all the sound comes from one place, but the Högtalare makes up for it with a huge amount of power that effectively bounces the sound off the walls and simulates a more realistic stereo sound.

I found music (of almost any type) to be more immersive than movies or games, and the clarity of the Högtalare created an exceptional musical experience, featuring thunderous bass drums, tambourines that I had never heard before on some of my favorite songs. The vocals in particular are simply amazing. I think the bass is a bit cleaner than the treble, but the delta is small here. Overall, the quality is far superior to that of a typical Bluetooth monitor – and, again, the system is very loud at full volume.

The only major complaint I’ve had with Morel Högtalare about the momentary shutdown was on the first day of testing via Bluetooth. I ran into this when connecting to two different devices (but not a third), so while I can’t rule out an issue on the side of my devices or in my environment, it seems a little random. Good news: I managed to solve this problem by “forgetting” about connecting to the device and reconnecting them.

Price 349dollars Högtalare can compete with other high-end bookshelves, although if you need two units, this calculation changes slightly. All in all, I wouldn’t hesitate to recommend it to any audiophile.

How to play music from your phone to your car stereo



Last updated 01/10/2023 by German Naumov

With the variety of audio entertainment available on your phone, you need an easy way to enjoy music, podcasts, audiobooks ami and other content in the car. But what’s the best and easiest way to play music in the car from your device?

Let’s take a look at how you can play music from your phone in your car, whether it’s old or new.

Universal option: Bluetooth FM transmitters from phone to car

Almost every car has an FM radio and cigarette lighter/socket that you can combine to play music with the FM transmitter. This is a great all-round option if your car doesn’t have Bluetooth or an AUX port; the required devices are relatively inexpensive and easy to set up. Keep in mind that this is not the same as using the FM transmitter apps on your device.

The exact setting varies, but these transmitters usually plug into your car’s power outlet (or cigarette lighter in an old car) and connect to your phone via Bluetooth. After tuning your device to an unused FM station in your area, you can play audio from your phone through your car stereo by tuning it to that station.

However, depending on the number of FM stations in your area and the specific device you purchase, the sound quality may vary. And music through the FM transmitter doesn’t sound as good as some of the other options.

To clarify: you cannot play music only through the cigarette lighter in the car. Although FM adapters plug into this outlet, you cannot play music directly through the cigarette lighter port.

Take a look at the best Bluetooth car adapters to find the right one for your needs.

For older cars: playing music with a cassette adapter

If your car is old enough and has a cassette player, you can use it to play audio from your phone. Cassette adapters are cassette-tape-shaped basic devices that have an external audio cable.

You simply plug the adapter into your cassette player and then connect it to your phone using the included 3.5mm auxiliary cable. Then play whatever you want from your phone and you’ll hear it through your car’s stereo.

Reviews vary, but this Arsvita cassette adapter should work fine and won’t break the bank.

Compared to FM transmitters, cassette adapters do not have many advantages. The cassette sound quality is not very good and you will have extra wire hanging around the dash. Also, most phones these days don’t have an AUX port, making this option impractical unless you buy an adapter for your phone.

We only recommend using the cassette adapter if your cigarette lighter/socket is not working, or if you cannot get a clear signal from the FM transmitter.

Reliability: Play Music with Accessory Cord

Most modern cars are equipped with an additional 3.5mm jack either on or below the stereo. This allows you to connect a cable from your device’s headphone port directly to your stereo. From there, simply play any sound on your phone that you would like to hear in the car.

The sub audio will sound clearer than the cassette and FM transmitter. Of course, this won’t work (without an adapter) if your device doesn’t have a 3.5mm headphone jack. But if both your car and phone have a stereo jack, it’s an easy way to play audio without any problems, as long as you don’t mind a wire.

If you don’t already have an accessory cord, Anker’s accessory audio cable should come in handy. Just remember that playing music through the AUX cord is not a “smart” method, so you will have to change the track and make similar changes on your device. You cannot use the controls on the car stereo or steering wheel with the optional cord.

Convenience: Music playback via Bluetooth Audio

Even if your device doesn’t have an AUX port, newer cars allow you to play music from your phone thanks to the car’s built-in Bluetooth. Simply connect your phone to your car’s Bluetooth like you would any other device (following the instructions in your car’s owner’s manual) and you’ll be able to play media in your car from whatever apps you like. See our introduction to Bluetooth if you’re unfamiliar.

Depending on your car, you can control media using your car’s controls, and you can also view song information on your car’s display.

Bluetooth is convenient because once paired, your phone automatically connects to your car for easy future streaming. It also has the advantage of allowing hands-free calls, which doesn’t work seamlessly with an auxiliary cable.

However, depending on your vehicle, sound quality via Bluetooth may not be as good as when using an auxiliary cable. Try both methods to see which you prefer.

The best of all worlds: playing music via USB

Many cars now have a USB port inside, making it the most modern way to play music from your phone in the car. Having a USB port in the car allows you to charge your devices without an adapter, and you can even plug in a USB stick for music if you want. But you can also connect your phone to play music directly.

If your car has a USB port, it is best to use it to play sound on your car stereo. Not only does it provide a reliable connection and clear sound, but it also charges your device and allows you to make hands-free calls.

Of course, for this you will need a spare USB cable for the car (an accessory you should always have in your car). Depending on your phone, this could be an Apple Lightning cable, a USB-C cable, or an old micro-USB cable.

USB input is the only option that allows you to play music from your phone in the car without any form of AUX or Bluetooth. It’s also the only way to use the phone’s handy feature for playing music in the car, which is…

Music playback with Android Auto and Apple CarPlay

More and more vehicles support Apple CarPlay and Google Android Auto. They allow you to connect your phone to your car’s head unit for easy access to music, navigation, messaging and more.

Not every car supports them, but if your car does, you should definitely use these features. Sleek interfaces as well as voice integration with Google Assistant and Siri make them a pleasure to use. We’ve covered how to get started with Android Auto and how Apple CarPlay works.

Even if your car’s infotainment system doesn’t support it, you can use the Android Auto-like Google Assistant driving mode right on your phone’s display. Combined with Bluetooth or a USB cable for audio, this setup offers almost the same experience as Android Auto on the head unit. Unfortunately, CarPlay doesn’t have an equivalent for this.

Select 2020 and newer vehicles also support wireless Android Auto and CarPlay, allowing you to use these features without connecting a cable.

Aftermarket Stereo Upgrade

We’ve only covered factory options and simple upgrades here. If you have an older car with no built-in USB, Bluetooth, or extras and don’t want to use an FM transmitter or cassette adapter, you can replace your stereo system entirely. This will allow you to use modern features such as USB and Bluetooth connections, and some even include support for Android Auto and CarPlay.

Performing a replacement is a moderately intensive task, not to mention more expensive than anything above. Thus, we do not recommend doing this unless you have experience in such work and really do not want to use any of the above options.

If you’re interested in this, Crutchfield is a great website to check out. It will help you find the right stereo for your car, and every purchase includes a detailed installation guide.

What is the best way to play music in the car?

The above options vary in sound quality and comfort. USB and auxiliary sockets provide the best sound quality but are not available on older vehicles, while cassette adapters and FM transmitters are of the lowest quality but are suitable for most vehicles.

Please note that other factors can affect the sound quality of your phone in the car. If you have an old car with crappy speakers, you probably won’t be able to see much of a difference between an auxiliary cable and an FM transmitter. The same thing happens if your car is particularly loud or you drive in noisy places.

In this order, from best to worst sound quality, we recommend the following ways to play music in the car using your phone:

  • If your car has a USB input, use it.
