How can I improve the sound quality of my car?
You can make several improvements to your sound system to make it reach its full potential. Hopefully, the pro tips listed below will help you a great deal and yield noticeable results.
Tips to Improve Sound Quality
Replace Car Speakers
More often than not, speakers come last in any manufacturer’s mind. They, therefore, do not give them the attention they deserve. Most of the new systems still use inexpensive speakers and amps, so the quality of sound is poor. You can change this by purchasing new aftermarket speakers, and you will be surprised at how significantly your sound quality will improve. A tighter bass and more clarity are expected.
Use High-quality music files
Whenever you store music files in a music player, they likely lose some frequency information due to compression. Do not settle for just the default settings. Instead, use little compression if you want to use an MP3 player, smartphone, or iPod in your car. You can also use a higher audio quality when you are streaming. A higher bit rate translates to better quality music as well.
Bypass your music player's built-in DAC converter
The built-in DAC may not offer a good enough performance in the car as with listening with earbuds. Your smartphone being your music player often, you will notice a difference when connected to a car stereo system. To avoid this, connect the smartphone to the aftermarket stereo through a USB stereo. That works to bypass the device’s DAC and thus a better sound quality.
Use sound deadening material
Engage sound deadening products such as Hushmat, and Dynamat to reduce exterior noises, vibrations, and road noise. That will improve the sound of the system. Firstly, do not install your speaker on a door panel- its thin metal vibrates, and the music is not accurate. The deadening products work to reduce vibrations and result in a more precise and stable sound. These products also serve to reduce interior noise levels in the car, so you do not always have to turn the music up for better sound.
Add a car amplifier
Car amplifiers boost any speakers for a more powerful performance. Installing a separate amplifier is essential as it provides additional power to any stereo. It makes a significant difference in making your system sound better.
Addition of a signal processor or equalizer
The interior of your car may also affect sound quality. For instance, plastic and glass surfaces reflect sound, while seat covers and carpets soak up the sound. Poorly located speakers make matters worse. The poor quality of sound may cause ear fatigue; an equalizer will come in handy to eliminate the peaks. They give multiple points for frequency response adjustment.
A parametric equalizer varies the width and center points of each EQ band so you can narrow down on the problematic area. Sound processors work to increase bass response and eliminate frequency response peaks. When an EQ is appropriately used, there will be a notable difference. You need to set it properly for optimal performance.
Build a better sub box
A subwoofer box should be sealed appropriately for better performance. Any air leaks will adversely affect sound quality. The sub box with correct interior volume is also important for superb performance. You can even resort to buying a premade enclosure that will work with your sub-box.
Most in-dash receivers now come with inclusive frequency filters that work with speaker and preamp outputs. For subs, high pass filters eliminate the low bass from full-range speakers. A cleaner volume will be achieved. Experiment with the cross-over points to find the ideal bass.
Set amp gains properly
It is noteworthy that the gains control only works to adjust the input signal delay amount that comes into the amplifier. When cranked up too high, you will experience a nasty distortion. The volume control of the receiver should be turned up to ¾ way, and then turn the gain amp up till a distortion is heard. Back it off and you are good to go.
Add a Subwoofer
Add a subwoofer, and you will be surprised at what you have been missing. A good subwoofer brings proper balance and accurate sounds. They also work to relieve the speakers. A subwoofer can be adjusted to preferred musical tastes.
