can线，双绞线，棕色线互相缠绕，说白了就是相互缠绕的普通铜线，用来传递波形信号
lin线，也是传递信号的，不知主要的信号线，不起作用情况下，不影响正常开车，但是会影响舒适系统，比如玻璃升降之类的
其他的，通电就可，
我的理解。
K线指的是通信线，诊断座上的7号脚。
音响线和普通线到底有什么区别，说法不一。但制造工艺是是有区别的。实事求是的说，花大价钱购买音响线（信号线和音箱线），不如把内部的关键器件换成高品质的。发烧信号线，不论是怪兽还是什么其他的大牌，一两米的价钱动辄几百，多者几千，但这些线比一般的线材（技术参数合格、价钱不超过几十块的）到底有多大差别，这个问题众说纷纭，评价的人多数是纯主观评价，带有强烈的主观倾向，心理作用在这些评价中起了主要作用。作为声音的评价，虽然不能避免主观因素，但可以利用比较经过严格的双盲实验来确定，下面是一份国外烧友的信，他进行了盲测，发现参加实验的人（这些人都是有经验的音响爱好者）无法区分线材的差别，甚至做不出正确的好坏判断，非常不可思议的是，参加实验的人都听不出用衣服架子（货真价实的衣服架子）做的信号线和怪兽线的差别。这个结果基本上证明了花大价钱购买昂贵的信号线材是一种盲目的行为，投资是毫无意义的，完全是被他人和自己忽悠了。当然，资金充足的人，满足一下自己的心理需求是无可厚非的。
转一封国外发烧友的信：
Dear audiophile;
In response to When is good enough, enough, (refering to hi-fi loud speakers) I think you missed the point after reading my epistle ...but then again, maybe that's what I get for assuming readers will "read between the lines".
A speaker is only good enough when it can duplicate the original sound it is duplicating with such a high level of accuracy that no measurement device, including the human ear/brain, can detect any difference between the original sound and the speaker's duplication of the same sound. Of course this is impossible with todays technology. Because of the fact the original sound must, in some manner, be converted to electrons which race down wires at the speed of light, which are resisted and capacitated which will always cause a difference between the original and replicated sound. Therefore, I ask the question, why strive for perfect replication if it is not doable? Further, since it is not currently doable, why should anyone labor over the concern of how accurate or "good" their speakers are, or in this case, when is good, good enough? What matters is if the speaker SATISFIES its owner with the clear understanding that the owner is not hearing anything remotely true to the original sound recorded on the replicating media.
A speaker is not a music reproducer because it cannot accurately reproduce the original sound of the music it is attempting to replicate. All a speaker can do is take what is fed into it electronically and produce a "resemblence" of the original sound. Therefor
你好！车载通信，祝您用车愉快！如果我的回复能帮到您，请帮忙选为最佳答案，非常感激！

汽车电路中CAN线是指通信总线，LIN线是指串行通讯网络，用于实现汽车中的分布式电子系统控制，而MOST是指汽车光纤线，利用光导纤维作为信息传导媒介，进行数字信号的传输。
因此，这些都是名词，不能代表导线的材料。
