The power supply for the audio system is connected from the positive terminal of the battery to the positive terminal of the amplifier (+12V), and the GND is connected to the negative terminal. Below is a detailed introduction to the car audio system: 1. Audio Source: The car provides Bluetooth, WiFi, and AUX interfaces as connection methods for audio sources such as mobile phones or players. Among these, the AUX interface offers the highest quality or even lossless connection, so it is recommended to use the AUX interface when playing music. 2. Speakers: A car's speakers include tweeters and woofers, and the sound quality and effects depend on the number and level of the speakers. Lower-end cars may have only two speakers, while high-end cars can feature over a dozen speakers for surround sound. There are various brands of speakers, with premium ones like Burmester and Harman Kardon. 3. Amplifier: Different tones have different frequencies. The role of the amplifier is to reproduce these frequency ranges, and the more powerful the amplifier, the wider the frequency range it can reproduce. Therefore, the quality of music playback is partly determined by the amplifier.

Is it necessary to register a car's wheel replacement?

Replacing the car's wheels does not require registration as long as the size of the new wheels is consistent with the original ones. However, if the size is changed, it will not pass the annual inspection, and registration is required. For registered motor vehicles, wheels of different styles and materials can be replaced, but the specifications of the wheels cannot be altered. According to the motor vehicle registration regulations, any changes to the body color, model, performance, purpose, or structure of a licensed vehicle, including replacing the frame, body, or engine, must be reported to the vehicle management office for registration modification. Before modifying the wheels, it is advisable to consult the vehicle management office to understand the situation; otherwise, the annual inspection may not be passed, and the vehicle may be required to be restored to its original condition. If the wheels are replaced with the same size, the annual inspection is generally passable, but the appearance should not change too much unless local policies are very strict.

How to Disable the Anti-lock Braking System?

The anti-lock braking system in the vast majority of civilian vehicles cannot be disabled. The ABS (Anti-lock Braking System) is enabled by default and remains on standby at all times unless a malfunction occurs. Whenever the vehicle shows signs of wheel lock-up, the ABS system intervenes to prevent the wheels from locking. If the wheels were to lock up, the rolling friction between the wheels and the road would turn into sliding friction, making it impossible to steer the vehicle with the steering wheel and greatly increasing the risk of a traffic accident. The Anti-lock Braking System, abbreviated as ABS, is an active safety feature in vehicles. In cars equipped with ABS, when a wheel is about to reach the point of lock-up, the brake fluid pressure causes the system to cycle rapidly, acting 60 to 120 times per second. This is equivalent to continuously applying and releasing the brakes, similar to the mechanical 'cadence braking'.
