How to Connect Phone to Car Speakers Without AUX

Getting new speakers for your car that sounds is great and all but the problem is that many cars doesn’t offer a way to connect your phone. That means that your new speakers will not play anything other than the normal radio and how fun is that? For this article, we are going to take a look at the different options you have if your car doesn’t support any kind of connection to your phone.

Getting new speakers for your car is fun and all. But these speakers will not be utilized as they should until you have solved the problem with listening to your own music. In 2018, most of us use Apple Music or Spotify but the problem is with older cars, who doesn’t feature Bluetooth connectivity. Some of them are offering AUX but with more phones dropping that, this is an increasing problem even there. So, let’s solve that problem once and for all today. Here are some of the best solutions for connecting your phone to car speakers without AUX.

Using an FM Transmitter

The cheapest option is to get an FM transmitter. The way it works is that the transmit signals to the car stereo using radio frequencies. You set the same frequency on both the transmitter and the car radio and once you connect the transmitter to your phone, you play music this way. It’s simple and easy to use.

The transmitters themselves come in different variations. You can get cheaper transmitters that you hook up to the headphone jack, but since we no longer have headphone jacks on our phones, that is out of the question. Instead, we have to use wireless technology, Bluetooth.

Nulaxy Wireless In-Car Transmitter

Nulaxy Wireless In-Car Bluetooth FM Transmitter

The Nulaxy Wireless In-Car Transmitter is a Bluetooth-device. You connect it to the 12V output in your car and then connect it to your phone using Bluetooth. This way, your phone will play its music to the transmitter and the transmitter will then forward this to the radio in your car. The Nulaxy device is also great in that it has buttons on it that you can use to control the music with, like switching songs back and forth.

Going with a solution like this will be the simplest way to connect your phone to your car stereo. It’s easy and it’s cheap. You don’t have to mix around with the cables in the back of the head unit.


But there are disadvantages to this solution as well. Since you will need a free frequency on the radio, it can be a problem during longer travels. A frequency that is free in your city might not be free in the other. It’s also common with disturbances from other electrical things and it also tend to break a lot in signal. I would say that Add choosing an FM transmitter should be temporary or for a one-time use. If it should be permanent, I would recommend another solution.

Getting a Car Adapter

A third option is to get a car adapter. This adapter will be connected to the CD-changer output on the back of the of the original head unit and will then trick the head unit that it’s a CD-changer while being something else. For this solution to work, you will need to know if you have a CD-changer output on the back of the head unit, I’d recommend checking the manual for your car.

There are many different models of adapters, all with different functions. Some of these adapters have only AUX and USB while others will also support SD-Cards and Bluetooth. To give you an example of an adapter, you can check this Yatour Bluetooth Car Adapter. This specific one is for Honda but you can find many others models specific for your car. This is something that is really important since there is no standard for CD-changer outputs so all connections will look different, make sure you get one for your specific car.


There are very few disadvantages to this solution. One would of course be if you don’t have a CD-Changer output on the back of your head unit, then you will have to go with any of the other solutions. Once again, you should feel comfortable to dismount the original head unit since the connector will be on the back of it. You will also have to store the adapter somewhere and route the cables to where it should be. Other than that, there isn’t that much.

Changing Head Unit

Changing head unit in the car is the best option, as it would integrate the connection in your car, it will look nicer and you will most likely get other benefits as well. However, it’s a bit more complicated and more expensive than other solutions. Today, most head units will come with both Bluetooth and USB port(s). Both of these can be used for listening to your own music and using USB will also charge your phone at the same time, which is nice.

Choosing the best head unit can be tricky, as it will depend on budget, features and what not. To help you out, we have created a double din head unit buying guide which you can use to find one that you like. If head unit is something that you would like to get, I highly suggest that you get a double din as it opens so many more doors. Ever wanted navigation in your car? You can get that with a double din.


As mentioned, the big disadvantage with buying a new head unit is that it can be much more complicated to install. If you are unsure of how electric wires work or not willing to disassemble your car to mount a new head unit, this is out of the question for you.

It will also destroy that original feeling, as most old cars didn’t have a 6”-screen in the dash from the beginning. If you are the one who loves your original dash, this might not be for you. On top of that, it’s not to say that it will be more expensive to get a new head unit. On the other hand, you get much more than you would get from a transmitter.


As you can see, there are quite a few options to choose from when your phone or your car is missing an AUX port. While getting a transmitter is cheap, getting a new head unit is the best and most stable solution. In my old car, that didn’t have any connections, I bought myself a car adapter as I wanted to keep the original stereo in the car. It worked great for the time I had it, until I bought a car with built-in Bluetooth.

But buying a new car might be a bit over the top just to get your own music, don’t you think?

What Does RMS mean and Why It’s So Important

Building the perfect audio system is a fun (and expensive) hobby that has kept audiophiles busy for decades, and with the advancement of technology, the hobby is getting more and more addictive as the years go by.

With that being said, audio technology is not the easiest thing to grasp, especially for beginners who are new to the game. Building the ideal system requires a solid understanding of several terms that are important to know in order to not only make the system work in the first place but also to perform at its best.

Understanding Ohms

Understanding Ohms on Car Speakers

When it comes to car audio technology, there is a lot to understand. One of the most common questions that we get asked and one of the most misunderstood specifications is “ohms”. What exactly does it mean?

Fortunately, understanding ohms is not that difficult. You only need to understand the very basics of what they are and what they mean in order to make your decision when purchasing new equipment that little bit easier.

Let’s start by defining exactly what ohms are and why they are an important specification that you need to consider when upgrading your system.

What Exactly Are “Ohms”?

In the most literal definition, ohms (Symbolized as Ω) is the term used to represent the impedance of a speaker. The impedance of a speaker is simply put, the resistance of the flow of electricity. The higher the ohms, the higher the resistance, the lower the ohms, the lower the resistance. Simple, right?

To give you an analogy, let’s imagine that the music you are listening to is water. If a speaker has a lower impedance, it means the “water pipes” are larger and wider, allowing more water to pass through without resistance. On the other hand, speakers with a higher impedance will represent a smaller, thinner water pipe, letting less water through and struggling to do so.

But what does this mean exactly? How does knowing resistance of an electrical current help me make a better decision when purchasing new speakers, and which is the better choice for me? Let’s break it down into a small FAQ to help you understand this concept a little more…

Ohm Calculator

What Are the Most Popular Choices?

You can find impedance ratings that range from 2ohms all the way up to 8ohms and beyond, but in the world of car audio, the two most common impedances that you will come across are 2ohms and 4ohms.

In car audio technology, 4ohms tends to be the norm.

Which Is Better?

Logic would tell you that 2ohms is the better option, as the lower impedance will mean less resistance to the flow of electricity, and that’s got to be a good thing, surely?

To make matters a little bit more confusing than they already are, the answer is, it depends. You can ask two different people whether they can hear an audible difference between music played through a 2ohms speaker or a 4ohms speaker (assuming the wattage is the same) and they could both give you completely different responses. It completely depends on the individual (and how much of an audiophile they are), but generally speaking, most people cannot tell the difference between the two.

With all of that being said, there have to be some technical differences between the two, so what is the difference between the two on a technical level?

2ohm impedance will typically produce a louder sound than a 4ohm impedance would (again, assuming the wattage is the same) but there is a slight decrease in sound quality when played at louder volumes. Whether you can hear the difference in sound quality is again, down to the individual, but in most cases, the difference is there.

With 4ohm impedance, you do lose a little bit of mids and treble, but the sound quality tends to be slightly better overall. Does that mean a 4ohm impedance is the better choice? Who knows!

So, Which One Should I Choose?

Luckily, we do have an actual answer for this one. When purchasing new speakers, or a new amplifier, you need to make sure that the impedance between the two matches. If your amplifier runs an impedance of 2ohms, you will need speakers that are equal to that. If your amplifier has an impedance of 4ohms, the same applies and you will need speakers that are equal to that.

The number that is presented in the speaker or amplifiers manual is simply an average, not an exact number. The impedance of a speaker will change constantly throughout a piece of music as the pitch of the notes changes. For example, a low E on a bass guitar will require a lower impedance than say a high F on a violin.

With that being said, as long as the number that is indicated on the amplifier and the speaker’s specification manual match, you will have no problems at all.

Rock On!

What Else Do I Need to Know?

Knowing the impedance that your amplifier can push is important to know when purchasing new speakers or subwoofers for your system, as choosing the wrong impedance equipment and overworking your amplifier can lead to the amplifier burning out.

However, the impedance is not the only thing that you need to take into consideration. Knowing the maximum RMS power rating of the amplifier is also an important figure that you must match up to your speakers and subwoofers. Don’t ever use the maximum (or peak) power rating when matching up your amp and speakers as this is not a true representation of the power output of a piece of equipment.

Once you understand the impedance and the RMS power rating of your amplifier, you can make your decisions without ever having to worry about them not working together, or them causing any issues in the future.

Hopefully, this short breakdown of speaker impedance has helped you to wrap your head around what it is, why it’s important and which one you should choose. “Ohms” is an important aspect of audio technology, but they aren’t the “be all end all”, so don’t beat you up over the choice. Like we said, the difference is honestly not that noticeable, so if you are building a system from the ground up, just make sure that the impedance of your speakers and amps match, and you will be fine.
