高音仔安装在A拄里，是菲力蒲的乌克兰制造。

     原车有没有分频器?通过拆卸发现原车的低音是直通的,高音上串接一个无极性电解电容,容量为4.7微法,给高音起滤波作用,要不要分音器要根据喇叭的参数来决定,有一些特例是不许要的,比如BMB和BOSE就是不许要大量分频元件的行家.但喇叭设计时就已作好了高低音的交叉频率.(图为原车高音的电容)

原车的机头是西门子，也有部分POLO的机头是SONY产的。

内部做工还可以

原装的机头运放是TDA7375,查资料功率为25瓦特4欧姆(1KHZ测得值)原车机头安装两片,即输出功率为25W*4

这是我改动的部分：

原车的高音是这样工作的,因为两个高音是对装,没有倾斜角度,懂音响知识的朋友知道这就造成中音的衰减,所以听起来炸,而切声场定位在驾驶台的玻璃中间不靠驾驶位,这是原车设计的问题,高音是这样工作的。

前低音安装在前门的下部,位置尚可。
