To purchase car audio, you should choose according to your actual needs and budget, under the guidance of professionals. Car audio mainly includes three parts: main unit, speaker and power amplifier. Currently popular hosts are: CD host and CD/VCD host (each type has a radio function) and DVD. The most widely used host is the car CD sound system. One thing is very important: before purchasing the host, you should first determine the amplifier, because different amplifiers have different requirements for the host. If you choose a power amplifier, it is best to choose a host with a higher front output current. The four volt output is better. The main speakers are double conical, two-way, three-way, independent components, subwoofer and so on. The independent components include independent tweeters and independent midrange units and crossover networks, which are usually installed in the front door of the car. In general, the larger the diameter of the speaker, the better the low frequency, so if you like to listen to the bass, it is best to have a speaker with a larger aperture. After selecting the speaker, decide whether to install the amplifier according to the speaker power and the budget of the whole set of speakers. Generally speaking, speakers with eight inches and more inches must be equipped with power amplifiers. The power amplifier has a great influence on the sound quality. Generally speaking, the same brand of power amplifier and speaker are better matched, should be considered first; if you choose brand-name car speakers and amplifiers, generally can be matched according to their technical parameters; for unknown brands It is best to actually listen to the audition. The power of the power amplifier is generally large. It is necessary to check the wire and insurance used in the installation shop. The unqualified wire and insurance not only lose power, but also cause fires, especially when installing a large system of multiple power amplifiers. And electricity should be fully considered. In addition to the above aspects, the wire and auxiliary materials used in the installation are definitely the places you should care about, including the tools, tapes and patch cords used, especially the transfer of antennas and signal wires. In general, manual wiring has a greater impact on sound quality and poor anti-interference. For the installation of large systems such as power amplifiers, it is also necessary to use MDF for speaker boards, speaker cloths, and waterproofing for vehicles. The quality of these materials directly affects the sound effects and vehicle safety. There is also a very important point, and it is also the most important condition for determining whether your chosen product can be effective and meet your needs – the technology of installing engineering technicians! Qualified installation technicians are familiar with the product operation characteristics and sound quality characteristics of various brands of car audio; secondly, they are also familiar with the sound lines of various models and the installation position and space of the speakers. Car audio and home audio are different. You need to consider various factors such as vibration, dust, heat dissipation, etc. The space inside the car is small, and the installation position of the speaker has a great influence on the sound quality. Therefore, it is best to install it in a professional car audio store with guaranteed quality. Don't be tempted to find a street shop just fine, so your loss will be great.
