Installation of the automotive acoustic system involves the installation of additional speakers and a subwoofer, replacement of the car stereo, and, as a rule, noise and vibration isolation of doors and other surfaces. The speakers are mainly installed on the doors. In order to install the speakers, it is required to disassemble them, to form the wiring, to connect, to check the speakers’ operability and to install the door. The subwoofer is usually installed in the trunk compartment or in the back of the rear seat. Installation of the subwoofer consists in installing the wiring and connecting to the on-board network, car stereo and amplifier. After installing the subwoofer, it must be adjusted. Generally, in order to work with such devices as additional speakers and a subwoofer, it is necessary to replace the standard car stereo with a processor car stereo.
