Is it really that simple to upgrade your car's sound system? With so many chaotic audio shops, countless "famous brands," and the complicated routes of car audio conversion, many car owners feel uncertain. However, upgrading a good sound system is not as difficult as it seems. If you understand the basics, you can confidently proceed with the upgrade. In short: everything is in your hands!
At Beijing Cool Car Town FEM Audio Station, we're here to explain the key concerns for audio converters. The address is No. 1, Cool Car Town, Jinxi West Road, Chaoyang District, Beijing, D3-11.
First, will the audio upgrade affect the car's wiring? Many car owners are hesitant to upgrade because they worry about damaging the original electrical system. But rest assured—audio upgrades don’t interfere with the car’s original circuits. The car audio system is a separate unit, independent from the rest of the vehicle's wiring. Even if you replace the factory stereo with a DVD or GPS system, it still uses its own dedicated power and signal cables. For example, when replacing a CD player with a DVD system, you just need to swap out the rear cable and follow the standard wiring procedure. This won’t cause any issues. If you add a power amplifier, it’s recommended to use high-quality oxygen-free copper cables for better performance and safety. These cables are directly connected to the battery and have no connection with the original car circuit. Just make sure the wire thickness matches the system's power requirements, and add gold-plated waterproof connectors for extra protection.
If you’re planning a larger system with multiple amplifiers, consider adding capacitors to stabilize the power supply. You might also want to install additional components like a battery booster. These should be placed in a way that keeps them hidden and secure. Even with these additions, there will be no impact on the original car wiring. It's all about smart installation and proper planning.
Second, how to choose a head unit? The market offers two main types: "dumb" units without built-in amplification and "smart" units with built-in amplifiers. Dumb units have strong signal transmission and better sound quality but require an external amplifier. They’re less common due to their higher cost. On the other hand, smart units come in single-disc or multi-disc models. MP3-compatible units are popular today because they’re easier to use and more affordable. However, they may not be as durable as multi-disc models. When choosing a head unit, pay attention to its output power. If you don't plan to add an amplifier later, go for a model with higher power. Look at the RMS (continuous) power rather than peak power. Also, check for multiple RCA outputs, which are essential for future upgrades. A host with more RCA outputs gives greater flexibility when connecting power amplifiers.
Another important factor is the output level of the head unit. Higher output levels (like 4V–6.5V) allow power amplifiers to work more efficiently, reducing distortion and improving sound quality. Choosing a high-output head unit makes the whole system more compatible and efficient. This is especially important if you plan to expand your audio setup later.
Third, how to upgrade the original car audio? Amplifiers are a crucial part of any upgrade. While most head units have built-in amplifiers, external ones offer better performance. A two-way or four-way amplifier is usually a good choice for most users, as they are cost-effective and versatile. If you want more bass, a single-channel amplifier can drive the subwoofer effectively. However, it's more expensive. When choosing an amplifier, look for features like high-pass and low-pass filters, which help manage frequency distribution. Signal-to-noise ratio is also important, as it affects clarity and reduces interference. A higher ratio means better performance and fewer unwanted noises.
Speaker selection is another area where many people get confused. Coaxial speakers are commonly used in cars, but they tend to have a column-like sound projection, making the sound less layered. Crossover speakers, especially two-way models, offer better sound separation and a more natural listening experience. They distribute the signal properly between high and mid-range frequencies, creating a clearer and more immersive sound field. For those who prefer a more detailed sound, a full set of crossover speakers is ideal. However, this can increase the cost significantly.
Speakers also have different characteristics based on their origin. American rock, German vocals, and British classical styles each suit different speaker types. Choose based on your personal taste and budget. Don’t follow trends blindly—what works for one person may not work for you.
Fourth, how to choose a good audio modification shop? Car audio is a complex system that requires both good equipment and professional installation. The saying goes, “Three-point equipment, seven-point installation.†Even the best components won’t sound good if they’re not installed properly. Professional shops take care of every detail, from wiring to placement, ensuring a safe and reliable result. They use high-quality materials like gold-plated connectors and thermoplastic tubes to prevent issues like overheating or short circuits. Avoid unprofessional shops that offer cheap services—they may save you money now but could cost you more in the long run.
In conclusion, upgrading your car audio doesn’t have to be overwhelming. With the right knowledge and a trusted professional, you can enjoy a rich, immersive sound experience. Whether you're looking for better bass, clearer highs, or a more balanced sound field, there's a solution that fits your needs and budget. Always do your research, ask questions, and choose wisely. Your car audio upgrade should be both enjoyable and stress-free.
