Super clean low mileage e46 M3 in for a sound upgrade. I somehow lost a bunch of pictures of the install but here are the ones I did have. We started out with a factory looking head unit to get modern features such as wireless Apple CarPlay. We 3D printed a mount to hold the Audison DRC MPCAN controller. The car was treated with several rolls of damping material. We added Voce ii component speakers in the factory door locations ran active on an 8 channel Forza amplifier. Audison Prima 4” coaxial speakers were installed into the rear locations on laser cut acrylic mounts. Lastly, we built a sealed enclosure that fits under the convertible top that holds 2 8” Hertz Mille Legend subwoofers that also serves as the amplifier rack. A trim panel was cut and upholstered in similar color trunk liner to factory and is held in by several magnets. Because the only way to get bass into the cabin is through the ski hole, we fabricated a custom grille with mesh on it allowing as much output as possible to get in. The DSP was tuned using a real time analyzer for optimal sound. Car sounded great when done, everything looks very factory and there is still room in the trunk for groceries!
