There are many methods of improving the Bluetooth sound quality of your car. These techniques will help create an overall premium sound quality in your vehicle. Here is a list of ways of improving the Bluetooth sound quality of your car.
Ways of Improving Bluetooth Sound Quality In a Car
Bluetooth technology has been in existence for an extended period now, and it gets better by the day. The sound quality has been improving over the years to a level where most high-end Bluetooth headphones and speakers sound almost similar to their wired counterparts.
Bluetooth technology has also made its way to your cars. As a result, Bluetooth-compatible sound systems in all kinds of vehicles have progressively become the main feature in more models.
Many smartphone owners love connecting Bluetooth stereo signals in-car audio receivers as it allows one to play music from their phones on the car stereo without any tangling wires.
However, despite the convenience of Bluetooth stereos, one should expect a degrade in sound quality that might become more noticeable when only playing on a premium audio system.
Therefore, if you want the convenience of both Bluetooth stereo connectivity and rich sound quality, it will be vital you choose the right components.
Audio over Bluetooth is usually transmitted via the A2DP profile and A.V.D.T.P. protocol. The audio stream is then encoded with a codec and then transferred. Finally, the receiving end decodes the signal and plays it back.
1. Change Bluetooth Codecs
If you connect your android smartphone to any device in Bluetooth, you can send music in a formula determined by the codecs. Codecs modify the size of the data packets to determine the speed of the transfer and the audio quality. Therefore, they will either maintain the packet size as much as possible to keep quality sound or compress them to reduce their size and transmit them faster.
In simpler terms, the more compressed the packets sent, the higher the overall transfer speed, which doesn’t need a strong connection. Therefore, reducing the quality.
On the other hand, the smaller the compression, the larger the packet size, maintaining the audio quality. Although that means that a strong connection is required, the transfer is not done fast enough, deteriorating the audio quality. Therefore, if you are in an area with fewer Bluetooth connections, little interference, and close to the audio source, choose high audio quality codecs.
If you are in a place with many people with a lot of interference, choose lower-quality codecs to allow faster packet transmission.
2. Upgrade your speakers
Installing a nice set of speakers will create a massive difference in improving your car’s Bluetooth sound quality and overall audio quality.
Factory audio speakers have become better over the last few years. However, most premium systems still use relatively cheap amplifiers and speakers that don’t deliver high-end sound.
Therefore, check if your speakers are old stock and choose to upgrade them.
A good set of speakers will deliver tight bass, more clarity, and more detailed audio than before.
I recommend OontZ Angle 3 for its quality sound, loud volume, serves a wide range of up to 100 foot, its portable etc.
3. Play higher-quality music files
When playing music on a sound Bluetooth audio system, you will tell something is missing from your music files if they are compressed. Therefore, when you want to use your smartphone, iPod, or MP3 player in your vehicle, try using as little compression as possible.
The higher the bit rate, the better the sound quality you get. Also, when streaming your music, explore the settings on your favorite music app to set up your audio quality.
You may choose to use a music service that streams music in higher resolution, such as TIDAL.
4. Reduce device activity
Reduce the number of apps you are using while listening to audio through Bluetooth sound system, specifically, apps that sync data or have access to G.P.S. on your device.
Bluetooth works by transmitting data through radiations of different frequencies. These radiations are affected by some material medium that comes in their path. Therefore your device won’t be able to transmit data to the receiver of your car. Therefore data syncing may interfere due to the other wireless activity going on.
Moreover, when streaming your music rather than listening to local files, ensure that no other apps use your internet bandwidth. Having minimal bandwidth reduces the quality of the streaming audio.
5. Upgrade your receivers or Bluetooth Car Adapters
As the versions continue changing with technological advancements, you should also ensure that you change your receivers to match the Bluetooth version you are using. For instance, your vehicle’s factory receiver will use corners in terms of audio output. This is because the audio output power will be too low to make the most out of your aftermarket speakers. Also, the quality of its digital to analog converter (D.A.C.) transmits the data signal from your device and converts it to sound. The better the D.A.C., the more you will realize noticeable details on your audio than before.
For a Bluetooth connection to work effectively on your vehicle, you must match the receiver with the same technology. Anker Soundsync A3352 Bluetooth Receiver, it delivers stable connection with its latest bluetooth connection, allows you to freely answer calls while driving and can support dual pairing.
6. Get an amplifier
To get the best out of your speakers, you will need a new amplifier despite the type of connectivity used. Adding a new Bluetooth amplifier will enable your speakers to produce more powerful sounds.
Moreover, it will allow you to stream wirelessly even when you don’t have a compatible Bluetooth stereo. Having purchased, installed and tested BOSS Audio Systems MC900B I highly recommend it, The music in my new Ford ranger is awesome and I love it.
7. Apply sound-deadening materials
Both road noise and interior noise can affect your car’s sound quality. Therefore, installing deadening or dampening materials in your vehicle will help you improve your sound quality as they cancel out the noise coming from inside and outside of your car.
This will also improve your comfortability as you drive.
These dampening materials include insulation sheets, deadening mats, and spray foams.
Apply or install them on hollow spaces like inside your car doors, trunk, or the floor.

8. Invest in an equalizer
A vehicle’s interior would cause problems when it comes to Bluetooth sound quality.
Plastic and glass surfaces reflect sound, while mats, seat covers, and other absorbent materials soak it up. Also, if you have placed your speakers poorly, the sound will be irritating.
Most receivers offer treble, mids, and bass controls, helpful in global fixes but insufficient in canceling the noise. Therefore, adding an equalizer with our best pick being Clarion EQS755 7 will help you kill the peaks and balance the frequencies you are receiving.
This will help improve the audio quality.
Wireless connections only work as well as the equipment connecting them. Therefore, with a good plan and assistance from a professional, it is possible to get convenient and premium audio quality through Bluetooth.
