Chevrolet, speaker installation in Israel

Chevrolet, speaker installation in Israel.
Additional speakers improve the acoustics in the car, and they are most often installed on the front doors. To do this, remove the door cover panel to open the places for the installation of speaker as envisaged by the manufacturer. They often do not match the installed devices, so it is required to expand the holes or use a special device, namely a podium. Lay the wires to connect the speakers through the door opening and install the speakers in the hole or on the podium.
