This is a 2016 where the customer wanted to add a sub / amp. We used two JL Audio TW1 Subwoofers and a XD600/1. He wanted to present the equipment in a way that looked OEM. He did not want to see any equipment, even through the grilles. On the main trim panel, I used two different grille materials. The grille in the center is inverted to showcase the depth and Maserati emblem that rests in the center. A half inch piece of acrylic accents the grills and design behind two pieces of aluminum. The aluminum design was taken from the steering wheel. Two quarter inch leather matched panels finish off the trim at the bottom. All access is still granted to the spare tire and battery. We made a acrylic mount painted silver to match for the bass knob in the center console.
