Factory-installed speakers are not of the best quality, but you can easily buy an aftermarket set that offers a wider sound range. If you want an upgrade, especially in terms of speakers, install a separate woofer and tweeters, as well as component speakers, to get good midrange sound.
Not enough power – If the sound quality simply seems to need more “impact,” your amplifier is probably the culprit. Since it provides more power to your new speakers, you should get more clarity without any kind of distortion.

There are not enough details. If you’re an audiophile with a passion for music, you know that layers of audio are essential for a complete listening experience. An upgraded head unit can help enhance your jazz or classical music hearing, elevating your listening experience to another level.
Evaluating your car’s audio system – If your car stereo sounds good to you, that’s exactly what all automakers are looking for. Even factory-installed premium sound systems are usually not that good. So how do you know if the factory sound needs a little affection?
Here’s a test that anyone can take:
Sit in your car and close all the doors and windows.
Play your favorite music and turn up the volume.
Don’t be afraid to go louder than usual, but try to avoid turning up the sound and going loud enough to burst your eardrums.
Listen to the music and start noticing the drawbacks.
If you need to boost the treble due to a lack of clarity, that’s something a speaker upgrade can fix.
If you turn up the volume of the bass, it will be hollow or empty, which is also something an upgrade can fix.
If the music sounds distorted when the volume is too high, this is another thing you can solve with some adjustments to the aforementioned amplification system.
