Does Car Audio Quality Depend on Speakers or the Head Unit?

[MacBrianna]

Car audio quality depends more on the speakers. Summary: To convert perfect electrical signals into sound, you have to rely entirely on the speakers. The speakers play an absolutely critical role in the audio system. Even if the head unit's parameters are excellent, it's all in vain if the speakers can't accurately reproduce the sound. Therefore, to achieve good audio quality in a car, you need high-quality speakers. Additional Notes: The main factors affecting car audio quality are noise-related. First, soundproof the doors, then upgrade the speakers to a high-end speaker set. These premium speakers require significant power, which the factory-installed amplifier can't handle, so a higher-power amplifier is necessary.
