Advantages: the audio source part can listen to all kinds of music you want online with QQ music, which is more flexible. In addition, it also supports USB flash drive and Bluetooth playback. The output resolution of the host computer is not bad. Resolution is the ability to output music levels and details. The endurance of the original car horn is still very good. The above points are my summary of the modified car and horn. ? Disadvantages: The main engine power of the original car is a bit low. The consequence of low power is that the volume output to the speaker is very small. The original car needs to be increased to more than 35 to satisfy me. The effect of vocal instruments is chaotic, the music is distorted and the bass is low. The original car is only three-level tuning, and the appropriate value can never be adjusted. ? Of course, if the requirements for music are not so high, the original car effect is still sufficient.
Why do you need to install DSP power amplifier? First of all, we should know what is DSP power amplifier: DSP is audio digital signal processing. The car music output is output to the speaker through the DSP power amplifier, which can increase the power of the audio signal output to the speaker, and the volume adjustment range of the car is wider. The frequency of music can be changed, where the frequency is high, it will be reduced, and where the frequency is low, it will be increased, which can greatly improve the resolution of the original car equipment and make the music more layered and not turbid. By changing the playback delay of each speaker, the sound field will be clearer and clearer.
In fact, the tool is very simple, because it is added, and there is no need to destroy the original car line, just disassemble the parts. Disassembling parts is the most important part, which will be introduced below. ? Details of required tools:? 1: pry bar of automobile interior trim panel, function: remove interior trim. ? 2: H2 Phillips screwdriver (large Phillips screwdriver), function: remove the fixing screws of internal parts. ? 3: 10 mm sleeve, function: remove 2 fixing screws of lathe main machine. ? 4: a big towel, function: the main machine is removed to protect the surrounding interior. ? The tools are simple. Just borrow them from an auto repair shop or a decoration shop.
Show your car first, the sky is blue, and you just posted a car model. Handsome photos on the front

Viewed from the side, it is still very atmospheric.
To install DSP, you must first find the main engine of the original car, first remove it from the air conditioning panel, and the co-pilot will remove it from the far right. All of them are designed with buckles, and the gray panel is very soft, so you don't have to worry about breaking it. The buckle is still tight, and Chang 'an's workmanship is ok. The crowbar is an orange simple tool under the seat.
After removing the air conditioning panel, unplug the air conditioning button. Note that the cable plug is buckled, so don't pull it hard. Then I drew red arrows with a cross screw, about six in all. I forgot to count. When disassembling, look at all the screws that fix this screen part.
The air conditioning panel is descending.
After the screw under the internal parts of the screen is removed, there is a plastic button on it, which can be broken off with a gentle force. Pay attention to the position of the red arrow button and use it in the right place.
Unplug the screen cable. Unplug the cable when the whole car is out of power to avoid burning the screen.
When these two parts are completely removed, you can see the host.
This is the screen and air conditioning panel with a layer of plastic removed, and you can see the whole picture of the car after removing it.
The overall view of the lathe is fixed with four screws, with a cross screw above and a hexagon screw with a depth of 10mm below, which can only be fixed with a sleeve.
Dismantle the main engine.
The red arrows are screw holes, two on each side of symmetry.
Just pull out the main engine of the car.
Hang this position naturally. In order to avoid scratching the inside, put a towel in advance.
Today's protagonist, the original customized version of the DSP amplifier.
All output interfaces are used to expand other devices in the future. Equipment such as subwoofer is not needed today, and there is no plan to install subwoofer today. It will definitely be added later, and the subwoofer is a vital part to supplement the bass of the sound field.
Tuning interface and mainline tail interface.
There is an ACC control line in the tail harness, which can be omitted, and insulation treatment is enough, because the locomotive integrates ACC control, and there is an ACC/HIGH switch in the above picture, which can realize the original locomotive control by setting it to the HIGH position.
Unplug the two plugs of the locomotive main engine and plug the two plugs of the DSP power amplifier into these two positions. This picture shows that the DSP power amplifier harness has been plugged into the car, so don't confuse it. Just pay attention to the color distinction of the wire harness.
Plug the car plug into the DSP wiring harness, just plug it according to the current position, without damaging the original car line at all.
Colors correspond to details. After all these are completed, thread the other end of the DSP harness from the inside of the engine room to the bottom of the whole central control, and then restore the original car parts in turn.
The board at the foot of the main driver is opened and pulled out. This picture shows the opening way of the co-pilot, and the disassembling way of the main driver is the same. Reach to the bottom with your finger, pull open the buckle of the interior trim panel, and then take it out to the rear of the car body. Don't break it to the side of the car. Internal testing buckle does not belong to this type.
Insert the tail cable into the main engine, plug in the tuning cable, put the USB end of the tuning cable under the main driver's seat, and plug in the computer for tuning later to fix the main engine. It is best to make a package with sponge material to avoid abnormal noise when driving. Fix the harness and you're done.
Here is the computer tuning interface, 3 1 frequency adjustment, which can make the music more delicate, and the sound stage can also be adjusted. This is basically a low-cost modification. You can continue to enjoy the warranty without destroying the original car line.
