Take the money to buy a DSP to buy a better Alpine CD host modification, the sound source is not good, and it is useless to install anything. Alpine's host comes with EQ sound.
-
It must be good, the effect is not to be said, it is a little expensive.

DSP power amplifier is a digital audio processor that improves sound quality and power without changing the original audio system of the car, can be connected to other communication equipment to adjust the sound effect, and the sound quality improvement after installation is still obvious If you want to listen to high-quality **, you can install one.

Strong digital flavor, just listening to the ear like, after a long time not to hear.

Advantages of <> DSP amplifiers:
1. The DSP power amplifier integrates the module into the amplifier, which reduces the volume a lot and saves a large part of the interior space.
2. DSP power amplifier supports computer adjustment, can support active crossover, adjust EQ, etc., so that you can have a better enjoyment.
3. The DSP power amplifier is easy to operate, even ordinary people can adjust their favorite style at will.
Obviously, the functions of the DSP power amplifier are more abundant, so the cost of installing the DSP power amplifier will be higher than that of the ordinary power amplifier, and some car owners have reported that some brands of DSP power amplifiers are more hot. However, the advantages of DSP power amplifier outweigh the disadvantages, so if you recommend all car owners to carry out audio modifications, if you have the conditions, you can directly install DSP power amplifier, so that you can enjoy a better experience.

The output power of car audio is generally small, and the sound quality of the audio is closely related to the output power of the power amplifier and the caliber of the speaker. In the case of the same power amplifier, when the output power and impedance of the speaker are the same, the sound quality of the speaker with a large caliber is much better than that of the speaker with a small caliber (if possible, the caliber of the woofer is best at 8 inches).
Therefore, in a limited space, try to use a woofer with a relatively large caliber. The second is that it is necessary to install a tweeter and drive it with a two-way crossover, so that there is not only a powerful bass effect, but also a crisp and transparent treble, and the two complement each other in terms of sound range level, so that the sound quality is more perfect. The two-way circuit diagram is as follows:
The l in the figure is a 200-turn hollow inductance coil wound with enameled wire.

Mainly high and high pitch speakers, if you are not listening to DJ **, it is best to turn the bass low, and turn the middle and high tones slightly higher, but the middle and high tones should not be turned too high, too high is easy to harsh.
-
It can definitely be improved, but the sound of the car is only listened to by one person, because the sound of the driver's seat is good, and the sound of other positions is not good, which is irreconcilable contradiction. Those who understand the audio, don't toss the car, and don't listen to it slowly at home.
-
The car audio is not installed, which is related to the installation of the speaker and the frequency division, which cannot be greatly improved. After adding DSP, you can appropriately adjust DSP to reduce bass and some harsh mid and high frequencies to achieve partial improvement, but you need professionals to adjust the EQ in DSP.
-
There is an effect, the DSP is set properly, even if you don't change the horn and power amplifier, it will have a certain effect. The setting is unreasonable, and it is not more difficult to listen to than the original.
-
The sound is not clear, it is recommended to change the horn and change the amplifier. Adding DSP will have a certain effect, and changing the horn will be effective and the cost will be lower.

The car stereo is a little special, and it is best to go to the car repair shop to consult

Although honey does contain a lot of sugar, it is rich in vitamins, and it is most suitable for people who have become fat and in poor health to replace their meals.

Green iguanas are easy to keep. The green hyena is a herbivorous lizard, and the maned lion lizard is a carnivorous lizard. Green hyenas also eat bread worms when they were young, like to eat oily wheat vegetables, and lizards like to bask in the sun to increase body temperature and replenish calcium. >>>More
Look at individual needs:
1. Look at the dosage, if the dosage is large, the speed of the laser should be a little more powerful, and the cost of a single sheet is relatively low. >>>More
Brand comparison is more abstract, should be more scientific than the product, I personally think that the workmanship of Junma Automobile is more excellent, in the 100,000 level of SUV, Junma's door is used with integrated stamping technology, the roof is laser welding technology, the workmanship is comparable to the joint venture brand.
