Upgrading your car's audio system doesn't have to be complicated. With so many options and shops offering "famous brands," it can be overwhelming for car owners. However, a good sound upgrade is more achievable than it seems. By understanding some key points, you can feel more confident in making the right choices. In short: the power is in your hands!
At Beijing Cool Car Town FEM Audio Station, we break down the main concerns of audio converters. Our address is No.1, Cool Car Town, Jinxi West Road, Chaoyang District, Beijing D3-11.
First, will upgrading your car’s audio affect the original wiring? Many people hesitate because they fear that changing the audio system might interfere with other car systems. But in reality, car audio systems are usually separate from the rest of the vehicle’s electrical circuits. They come with their own dedicated power cables and connections. For example, when replacing a CD player with a DVD system, you just need to replace the back panel cable and follow standard wiring procedures. This ensures no interference with the original wiring. If you add a power amplifier, it’s recommended to use oxygen-free copper cables that match the system's power requirements. These cables are connected directly from the battery and are not part of the original circuit, ensuring safety.
For larger systems with multiple amplifiers, capacitors or additional power supplies may be needed. These components should be installed in a way that keeps them hidden and protected. This not only improves aesthetics but also enhances safety without affecting the original car wiring.
Second, how to choose a head unit? There are two main types on the market: “dumb†units without built-in amplification and those with built-in amplifiers. The former typically offers better sound quality but requires an external amplifier. The latter is more common, with options like single-disc or multi-disc players. MP3-compatible units are popular due to their ease of use and lower cost. When choosing a head unit, look at its power output (RMS) and the number of RCA outputs. A higher RMS power means better performance, especially if you don’t plan to add an amplifier later. Also, high-level output (like 4V–6.5V) helps improve the efficiency of power amplifiers.
Third, how to upgrade your factory audio system? Amplifiers play a crucial role in enhancing sound quality. While most head units have built-in amps, external ones offer much better performance. A single-channel amp is ideal for subwoofers, while a two-way or four-way amp is more economical for general use. Look for features like HP and LP tuning, which help optimize sound. Signal-to-noise ratio is also important—higher ratios mean better clarity and less interference.
Speaker selection is another key factor. Coaxial speakers are common but may lack depth compared to crossover speakers. Two-way crossovers provide better sound layering and reduce listener fatigue. The choice of speaker also depends on personal taste—American rock, German vocals, or British classical—so pick what suits your style.
Subwoofers, or woofers, vary in size. 8-inch models are good for general use, while 12-inch or larger ones are better for cars with tight interiors. Hatchbacks, being more open, may not need large woofers. Ultimately, it’s best to test different options after installation to find what sounds best to you.
Lastly, choosing a reliable audio shop is essential. Car audio is a complex system that requires proper configuration, placement, and installation. A professional shop will handle everything from wiring to testing, ensuring a safe and high-quality result. Avoid cheap, unprofessional shops that may cause long-term issues. A well-installed system can make your music experience truly enjoyable. So, take your time, do your research, and make an informed decision. With the right guidance, you can turn your car into a mobile concert hall!
