This was a full Focal Flax speaker setup with Mosconi 6to8 DSP. I built an enclosure with a beauty panel for the Flax 10″ subwoofer. I took modeled the design after the grill in the lower front foor panel. It is a multi level dual press grill setup. The materials were matching brown and black vinyl and brushed aluminum. The panel is made from PVC and used magnets to hold on the trim ring / grille. The customer still has access to the spare tire and floor hold downs.
The Alpine PDX amplifier and Mosconi 6to8 DSP sit on a custom panel bolted to the OEM amp mount. You can fold down the access panel for easy access and tuning.
