Earmark began this BMW by removing the factory radio and installing an Alpine factory replacement system with a touch screen interface, called the vehicle hub.
A dash bezzle was fabricated to disguise the aftermarket system as a factory screen.

In order to integrate into/with the factory upgraded sound system, we built crossovers wired to the front 3-way speakers and allowed them only to play the frequencies they were designed to play.

In the trunk a sealed enclosure was built for a Boston Acoustic 12-inch G5 and fired through the ski boot for better volume in the cab.

To keep it looking factory Earmark built a false wall in the trunk which hides the box and allows the amp to stay cool.
