Nothing but the best for this Maserati Quattroporte.

All doors removed. New front and rear speakers being installed. Wires being run inside the doors for new speakers.

The original bose speakers of a maserati. These speakers are being replaced with some premium hand made speakers from France. Every high end car should have Focal’s!

Dash speaker removed and replaced with Focal tweeters. Custom plate made to mount the speaker. Once the grill goes back on it will look factory.

The front doors don’t come with any speakers…..ULTRA AUTO SOUND to the rescue!

Custom made speaker plates for the front doors. A flat surface for the new focal speaker to sit in.

Focal speaker and mount installed onto the door. Looks like OEM.
