What Are the Pros and Cons of Car Audio Modification?

Car audio modification has the following pros and cons: Advantages: The sound quality becomes clearer after modification. Generally, the original audio systems in mid-to-low-end cars are not clear enough, and sometimes even produce static noise. Replacing them with a good amplifier and audio system can naturally solve this annoying problem, improving your mood; The soundstage positioning becomes more accurate. In some car models, the rear speakers are virtually non-functional, making it seem like the music is only coming from the front when played. Modified car audio systems can make the entire sound effect more immersive, with significant improvements; The noise insulation and reduction effects become better. Disadvantages: The audio market is mixed with good and bad products, making it easy to purchase counterfeit items. Therefore, it's essential to do your homework before modification and avoid being lured by cheap deals; For audiophiles, modifying the audio system can be very costly.

Do manual transmission cars need to change the gearbox oil?

Manual transmission cars do need to change the gearbox oil. The replacement interval for manual transmission fluid is relatively long, typically every 2-4 years or 60,000 kilometers. If the vehicle is not used intensively, it can be changed every 100,000 kilometers. For high-intensity usage, replacement is recommended every 60,000-80,000 kilometers. Transmission oil operating under prolonged high temperatures can deteriorate or evaporate, accelerating wear on mechanical components, and in severe cases, may damage internal transmission parts. The hazards of not changing transmission oil include: 1. After prolonged non-replacement, the vehicle may experience weak acceleration when starting cold. 2. Over time, the transmission oil becomes thicker, potentially obstructing the transmission cooler, leading to excessively high oil temperatures and increased wear.

How to Distinguish Between Good and Bad Spark Plugs?

Methods to distinguish between good and bad spark plugs are: 1. If the spark plug is blackened as if smoked, it indicates that the cold/hot type of the spark plug was incorrectly selected, the air-fuel mixture is too rich, or engine oil is seeping up. If the spark plug is reddish-brown or rust-colored, it indicates the spark plug is normal; 2. If the spark plug is severely eroded, with scarring, black streaks, cracks, or melted electrodes at the top, it indicates the spark plug is damaged and must be replaced immediately; 3. Let the engine idle and listen carefully for changes in engine speed and sound. Obvious changes in speed and sound indicate the spark plug is normal, while insignificant changes indicate the spark plug is in an abnormal state; 4. Unscrew the spark plug and place it on the engine block, then test for spark with a high-voltage wire. If there is no spark or the spark is weak, it indicates the spark plug is leaking electricity or not working.
