When modifying car audio by yourself, pay attention to the following: Style and Budget Issues: The combination of car audio must cater to your personal taste. As the saying goes, different strokes for different folks, and everyone has their own preferred style, coupled with a limited budget. Budget is also a very important factor. The Bucket Principle: When matching equipment such as the head unit (audio source), amplifier, and speakers, besides the style issue mentioned above, balance should also be considered—this is the bucket principle. Selection Method for the Head Unit (Audio Source): The head unit is the audio source of the entire system and also a control center; all operations on the audio system are performed through the head unit. It is recommended to choose a head unit based on five key aspects: sound quality, functionality, quality stability, price, and aesthetics. Imported big-brand head units have mature technology and excellent production processes, offering better sound quality than domestic head units. Matching Speakers and Amplifiers: When selecting speakers and amplifiers, first pay attention to the style issue mentioned in the first point. The final style of an audio system is 50% determined by the speakers, 30% by the amplifier, 15% by the front-end audio source (head unit or preamplifier), and 5% by the cables. It is best to choose amplifiers and speakers of the same style; otherwise, the effect may be incongruous at best, or damage the equipment at worst.

Modifying your car audio system can be quite fun, but you need to be careful. The first step is checking what type of audio system your car supports – don’t just randomly buy new equipment. I once bought a big speaker online without checking, and it didn’t fit in the door panel, wasting my money. It’s best to measure the door panel dimensions and match the original car’s power output to avoid blowing fuses. When installing, always disconnect the power and use a wrench to carefully remove panels—don’t force anything to avoid damaging wires. Secure all connections tightly; loose wiring can cause short circuits or even fires. Adding some soundproofing foam can improve audio quality—simple yet effective. Don’t forget to test the system after installation—start the car and check if the system smokes or trips unexpectedly. Take your time with preparations; rushing can lead to problems.

When doing car audio DIY, the focus is on power management. I've tried it many times and found that power mismatch is a big no-no. For example, when choosing a subwoofer, don't exceed the original car battery capacity, otherwise the car will struggle to start. The wiring should be clear, use copper wires instead of aluminum, and ensure good contact to avoid hissing noise. Prepare tools like a Phillips screwdriver and pliers to save on labor costs. Remember to install a fuse to protect the circuit, otherwise a short circuit will ruin everything. Tuning is also crucial, don't just pursue booming effects; use the equalizer to slowly find the right balance. Also, add an anti-vibration pad to prevent sound distortion on bumpy roads. Be careful throughout the process, don't rush and mess it up.

Straighten the wheels when the car is almost aligned. When the car is farther from the upper right corner of the garage and the distance is significantly more than 30 cm, let the car tilt and wait until the left rear wheel enters the garage beyond the upper left corner, then straighten the steering wheel and turn it to the left.

What are China 5 and China 6 vehicles?

China 5 vehicles refer to automobiles that comply with the National Phase 5 Emission Standards for motor vehicle pollutants. The China 5 standard imposes stricter limits on vehicle emissions such as hydrocarbons and carbon monoxide, aiming not only to reduce air pollution but also to prevent smog. Vehicle emissions refer to harmful gases discharged from exhaust, including carbon monoxide, hydrocarbons, nitrogen oxides, and particulate carbon smoke. China 6 vehicles are those that meet the National Phase 6 Emission Standards for motor vehicle pollutants. China 6 vehicles emit fewer exhaust pollutants than China 5 vehicles. The China 6 emission standard is implemented in two phases: China 6a and China 6b, with China 6b being even more stringent than China 6a.
