It was Ferrari Friday here at Sound in Motion! This 2026 Ferrari 296GTS came to us straight from the dealer for an audio upgrade. It was more complex than just upgrading some speakers. We custom installed Mosconi PICO amps, custom fabricated and fitted a sub box for behind the passenger seat, and so much more. Stay tuned for the full video!
The new Porsche 992.2 Turbo S Cabriolet is here and we have one of the first in the country here at Sound in Motion. Before handing it over to our CarDone team for new paint prep, we installed a radar/laser system seamlessly into the front and rear bumpers and crafted a custom control unit.
