Is it better to modify a battery or a capacitor for car audio? After reading it, you will increase your knowledge

In car audio modification, players often ask such questions. They all have one thing in common and know the importance of “electricity” in the audio system. How to improve the quality of electricity requires a more professional explanation. Riders are often at a loss when it comes to choosing. They see that someone’s system is equipped with capacitors, and there are several capacitors installed at a time; Some people have also seen that the system is equipped with batteries and no capacitors. Which one to choose is suitable for you?

 

First of all, we must deeply understand the relationship and performance characteristics of the two

1. Battery

 

As we all know, music is a process of electro-acoustic conversion. “Electricity” is as important as human blood in audio, and “battery” is the most direct provider of energy in audio system. At present, there is a kind of “special battery for audio” in professional audio modification, which has the advantages of surprisingly fast discharge speed, high purity of electricity, large energy storage and small size.

 

2. Capacitance

 

The general size of car audio capacitors: most of them are cylindrical, with a diameter of 78 MM; High 275 MM. Most of the car audio culture in mainland China is borrowed from Hong Kong, imitating and learning. The original name of “capacitor” is commonly known as “pond”. The capacitance of the car audio power system is the reason why Hong Kong is commonly known as “pond”. The most basic function of the capacitor is to store the energy of electricity, and it can be directly distributed there where it is needed, not intelligent distribution. It is not an exaggeration to simply and rudely understand it as a “water tower”.

Capacitors are installed in the car, mostly in the rear trunk, and a main power cord is drained from the original car battery in the engine compartment to the capacitors and connected in parallel. The length of this main drainage power cord is generally between 5-8 meters, and the stored energy of the capacitor is provided by a battery of the original car.

Car audio system is generally composed of multiple subsystems, including host, speaker amplifier, bass amplifier, etc. When a subsystem demands a large current, the capacitor plays a role in providing it quickly at this time. When all subsystems demand more current, the capacitor acts as a storage medium, and the stored circuit is long, resulting in a certain time difference. When the stored electric energy is always exhausted, the resulting sound effect will cause similar results: bass distortion, frequency band control confusion, more reverberation, and more “tailing”.

 

Effects of electrical energy on the system

The power of the audio is provided by electricity, which can basically determine the power. Insufficient power supply will naturally lead to power loss. Insufficient power will cause the power amplifier to output DC current instead of AC sound signals, resulting in burning out of the speaker. Therefore, when the speaker is burned out, most of them are caused by insufficient power of the power amplifier, rather than excessive power.

The “special battery for audio” can stably provide the electric energy required by the system for a long time, and the instant discharge speed is fast, and it will also improve the purity of electricity and sound quality.

Compared with the “battery”, the “capacitor” is a water tower. It has no characteristics of self-produced electric energy and can only be stored.

Speaking of which, I believe all readers can basically know how to choose a battery or a capacitor. Most people choose capacitors, probably because the cost of capacitors is low, and more because they don’t have a thorough understanding of the knowledge of sound modification. You must choose useful accessories and equipment for car audio modification. It seems a little expensive, but it is very cheap to use.
