Different owners focus on the different requirements of the car DVD players, and some focus on appearance, and some focus on sound quality, while others focus on function, and some focus on cost-effective, so you should make comprehensive comparison in the same grade nissan dvd player products according to your needs when buying a DVD player, and weigh which specific product is most suitable for you.
The first step to buy car DVD player is to determine whether the size of the machine is suitable for your car. From Car DVD Panel Size point of view, conventionally there are 1DIN and 2DIN two categories, generally small vehicles use1DIN size products, occupying a standard CASE. The size of the 2DIN device panel is relatively large, many products look more luxurious, which are mostly used for the commercial vehicle and other vehicles. Some cars also need to transform the vehicle if you want to want to install 2DIN size equipment. It is recommended that generally small vehicle users try to use the 1DIN standard size equipment, so that it will be relatively easy to install and replace the original deck. Single Din DVD is divided into two categories, with screen and without screen. The single spindle DVD has high module integration requirements because of the small size, so the production costs will naturally increase, or it has screen, then the screen must be made as telescoping (Built-in), so prices naturally come up. Some owners choose a single spindle vw navigation dvd without screen and a single spindle telescopic display, which first requires the installation space is a two-ingot, but two single spindle machines heat dissipation together is relatively larger than a single spindle with screen, so it is recommended to use a single tablet with a screen. Double Din DVD also has screen.
The second step is to determine the structure and grade of the DVD player according to your budget and needs. Car DVD player is divided into single-disc, multi-disc from their own structural characteristics. Multi-disc DVD player is available for front multi-disc players, and rear multi-disc players with a "backpack". The structure of the ordinary single-disc DVD player is simple, and the price is relatively cheap, which suitable for middle and low end cars. The benefits of multi-disc player is easy to change discs, but because a cable is needed between the disc box and DVD host, there will be a certain loss to signal, and will have a certain impact on the interference in the car, of course, high-end CD changer will use digital processing at all costs, so prices have soared. In fact, for general owners, manual CD changer is not trouble, which is able to save thousands of money on the cost, so single platter is also an affordable choice.
The third step is to weigh the performance and functionality of the different grades of products. If you love music and like to listen to some large dynamic audio song, then you can look at the output functionality and sound quality of the DVD player. Car DVD player output power is related to the music dynamic performance ability. Now DVD player nominal output power per channel is at 30 ~ 55W, 4 channel output, which can directly drive ordinary speaker. Some high-end car DVD does not contain amplifier, which requires an external dedicated car amplifier work. Generally, external professional amplifier performance is superior to the built-in amplifier unit DVD player, and more powerful.
