Is everything the bigger the better? For example, in a car audio system, is the power of the speaker also better? This question is often asked, but is there a standard answer? Today, let's talk briefly.
The power of speakers is divided into two types: rated power and peak power. The power indicated by speakers in the market is generally the peak power, which is also the maximum power that can be achieved by oneself. This high-power speaker often becomes its selling point and a gimmick for promotion. Many people who are not familiar with car sound systems feel that the higher the speaker power, the better, so they blindly approach it.
In fact, the maximum power of a speaker is often not needed, and even if the volume is turned up to its maximum during use, the sound cannot reach a high fidelity state. If the power of the car audio system is constantly exceeded by the matching power of the vehicle's electrical equipment, it will cause the car battery to be in a state of long-term battery depletion, thereby affecting the battery life.
The power of a car horn refers to the amount of power it can withstand, which is not related to sound quality, but rather to the power of the amplifier. The sound emitted by the speaker requires an amplifier, which has a high power and can boost the speaker, resulting in better sound quality.
For example, if a speaker with a rated power of 60W is paired with a 100W power amplifier, the distortion of the speaker will be relatively reduced, and the sound quality can be guaranteed. There is also talk of distortion in power amplifiers. A 100W power amplifier can only turn on 50W at half the volume, resulting in low distortion and significantly improved sound quality.
A 50W power amplifier, with only half of the 25W turned on, has good sound quality, but with only 25W, the sound will be much lower, which only has charm when the volume is lower. If you drive 50W, the sound is easily broken and the loss is loud. So, a 25W speaker paired with a 50W amplifier is better than a 25W amplifier. Of course, the power of the power amplifier is not necessarily the better, and it cannot be determined based on actual situations.
Overall, when upgrading car audio systems, it is important to consider the matching issue between the speakers used and the power of the amplifier. It is recommended not to choose speakers with higher power than the amplifier. This way, when you turn up the volume, the power output of the amplifier can easily exceed its rated power, resulting in wave attenuation distortion. In severe cases, the coil of the speaker may be burned, ultimately leading to damage to the speaker.
Maintaining the "margin" of the amplifier is an important factor in the matching of car audio systems. Considering the extremely limited electrical energy in the car, ensuring that the rated power of the power amplifier is slightly higher than the rated power of the horn is the most optimal choice.
To make the sound quality of the speaker sound resistant, in addition to the hardware design of the speaker, the selection of power amplifier or DSP power amplifier also needs to be matched, and finally, installation and debugging. There should be no mistakes in every aspect of equipment quality, matching, installation, debugging, and car audio modification, otherwise there is no need to discuss sound quality. So, judging the sound quality effect based on the power of the speaker is one-sided.
