Modifying car audio is not illegal, and there is no need to report the changes to the vehicle management office. It can also pass the annual inspection smoothly. Laws and regulations on car modification: According to Article 16, Item 1 of the Road Traffic Safety Law of the People's Republic of China, no unit or individual may assemble a motor vehicle or alter the registered structure, construction, or characteristics of a motor vehicle without authorization. Penalties for illegal modifications: If an exaggerated large rear wing is installed without proper registration with the vehicle management department, once discovered by traffic police, points will be deducted, usually 2 points. For illegally modified vehicles, the public security traffic management department will not issue a safety technical inspection compliance mark. If it constitutes a violation of public security management, the public security authority will impose penalties such as fines or detention in accordance with the relevant provisions of the Public Security Administration Punishment Law.

I'm a car enthusiast with quite a bit of experience in audio system modifications. In most cities, modifying your car's audio system isn't illegal per se, but the key is not to compromise the vehicle's safety systems—like tampering with airbag wiring or affecting the brakes. Also, be mindful of noise control; blasting your music at night might attract police attention for violating noise ordinances. It's best to have the installation done by professionals to avoid risks like electrical shorts or fires. This way, you can enjoy enhanced music and driving pleasure while staying within the rules. A quick tip: don't get too carried away with high volumes; maintaining neighborhood harmony is crucial, or you might end up with more trouble than it's worth.

As someone who frequently deals with cars, I can clearly tell you that changing the stereo system is generally not illegal, as long as it's installed properly. Don't tamper with the vehicle's original safety devices, such as airbags or the engine control module. Keep the volume at a moderate level to avoid violating noise regulations and incurring fines, especially in residential areas or on highways. When doing it yourself, pay attention to electrical safety, and it's best to have a professional assist with testing. Overall, legal modifications can enrich your life, but always prioritize safety and avoid reckless actions.

What to Do When the Nissan Sylphy's Battery is Dead and Won't Start

Need to bring the two cars as close together as possible. Generally, the car battery is located under the front hood. The two cars should be parked side by side or head to head. Next, locate the batteries of both cars, identify the positive and negative terminals, remove the terminal covers, and use the red battery cable clamp to attach to the positive terminal. Then, attach the red clamp first, followed by the black one. Once all four terminals are connected, the jump-start setup is complete, and you can proceed to start the car with the dead battery.
