In this Rolls-Royce, the original 1-DIN car radio was replaced with a modern 2-DIN navigation unit. For this, the cigarette lighter and the seat belt warning light had to give way and the center vent outlet had to be moved down a few millimeters. The Zenec ZE-NC2041D was installed because it has a very simple and symmetrical look.
On the housing of the air conditioner in the trunk was installed Zapco digital amplifier. This device is a dream and made for such cars: The built-in processor makes equalizing and runtime correction possible without me having to install controls that do not match the style of the car. Just dock it to the laptop via USB and adjust from the comfort of the driver's seat! And that paired with a sound that is second to none!
A 16 cm 2-way system was installed in the front doors. The woofer was screwed onto the door panel - the tweeter was recessed into the door trim.
The rear system was mounted to match the front system.
To give the system the necessary bass, a subwoofer box was mounted centrally under the dashboard. A 16cm subwoofer chassis was mounted in each of the left and right sides, which provided significantly more bass than one would initially expect from a 16cm subwoofer.
