濟南汽車音響http://www.szanyuda.com/電子分頻器是將音頻的弱信號進行分頻，然后傳輸給功放，讓其放大音頻信號，最后傳輸給各個揚聲器。電子分頻器主要由各種晶體管、集成電路和阻容組件組成，并且阻容多為純銅制作。
Jinan car audio electronic crossover is weak audio signal frequency, and then transferred to the PA, allowed amplification of the audio signal, and finally transferred to the respective speakers. Electronic crossover mainly by various transistors, integrated circuits and resistive and capacitive components, and RC-mostly copper production.

濟南汽車音響http://www.szanyuda.com/電子分頻器從汽車主機上面接受到弱音頻信號，然后將其區分，哪個信號是需要高音喇叭表現的，哪個信號是需要低音喇叭表現的，這些都要通過它進行區分，然后傳輸給功放，讓功放將信號進行放大過后，傳輸給每個部位揚聲器，這樣做的好處便是信號干擾、提高動態范圍，并且自身也有一定的放大作用。這樣就使得每個揚聲器能更好的展示其音質效果。
Jinan car audio received from the bus master electronic crossover above the weak audio signal, and then differentiate, which signal is required the performance of the tweeter, which signal is required the performance of the woofer,these must be distinguished by it, and then transmits to the amplifier, so that the amplifier amplifies the signal after transmission to each part of the speaker, the benefits of doing so is to signal interference and improve dynamic range, and there is a certain self-amplification. This makes each speaker to better showcase its sound quality.

目前在進行濟南汽車音響改裝時，安裝電子分頻器的辦法主要有兩種。安裝在車門內飾板內。這樣安裝，需要車門內飾板空間比較充足，最好有凹槽部位。安裝汽車儀表臺下方，安裝時需注意線路排放，以免對車身內部線材帶來影響，還有一種就是進行倒模安裝。不過這種分頻器安裝方式比較復雜，一般只適合后備箱倒模的車子安裝。
Currently modification, the installation of an electronic crossover, there are two main ways to making Jinan car stereo. Installed in the door trim panels. This installation, you need plenty of space for the door trim panels, the best part of a groove. Installed beneath the car dashboard, should pay attention when installing emission line, so as not to impact on the body inside the wire, there is a reverse-mode installation is carried out. However, this is more complex divider installation, generally only suitable for the trunk of the car down mode installation.
