Talk about the understanding of pair of car acoustics line

When a lot of cars are installing acoustics, talk about sound equipment only, oversight wire, especially oversight the stand or fall of line, again good horn, effect, if did not provide reasonable line, its acoustics also can sell at a discount greatly, so what is meant by line?

Line uses signal of deferent news source technically. Basically include: Coaxial line, digital letter line, fiber-optic line. Coaxial line is most all-pervading standard line, the effect machine that can reach great majority to the standard CD that sells on the market at present, DVD, MD undertake conjoint receiving, use very extensive, have certain interference rejection capacity, we are most now use frequency line is this kind of line; Digital line is a kind of coaxial line, what differ with coaxial line is, its transmission rate is rapid, transmission frequency band is broad, interference rejection capability is strong, in suggesting to match in a bit a bit more high-grade equipment, use; Fiber-optic line and digital line function are same, it is it only what what convey is the digital light that comes from source of news of CD, DVD signal, because date of digital electrical wiring is in source of news of CD, DVD,had report / smooth transition, the interference rejection ability of fiber-optic line is so ambitious at digital line, fiber-optic it is best line, also be the most expensive line, near 1000 yuan of RMBs.
