It was a little bit of everything this week at Sound in Motion. First, we enjoyed the company of this stunning, fully restored 1972 BMW E9 that stopped by for an audio consult on a different car. We also got to work on this Ineos Grenadier, which now leaves us with a new audio system and 360° camera, while a unique Mustang RTR is in the process of a full audio makeover.

British, German and American! It’s a little bit of everything here at Sound in Motion. We’ve got this Bentley Continental here for a custom audio system, the draw-droppingly beautiful Mercedes-Benz SLS AMG getting radar/laser protection and a custom audio system, and a Ford F150 here for some sound deadening and an audio system upgrade.

⚾️ We had a call from a Boston Red Sox player who had an idea for his RAM TRX. So what did we do? A seamless Baja bumper and light install. OEM look with lights controlled by OEM switches. Whether the idea is big or small, we’ll get the job done. ✅

Classic cars and trucks don’t always come with the perfect OEM set up for an ıpgraded sound system, but luckily enough, that’s our expertise. We custom fabricated these tweeters for this F150. You’ll never know they are aftermarket!

Sometimes we’re working on high performance exotic cars and sometimes it’s classics like this F150! One thing remains the same, and that’s the high-quality audio upgrade we provide. This F150 will be getting some modern audio upgrades complete sound deadening, new amps and sub box. Stay tuned!

After years of track days, this Porsche Cayman S Sport is ready for some more daily driving and a better audio system. We’ll be replacing the factory speakers with Focal Slatefibers and adding some extra power with a Mosconi amp.

Even James Bond needs a good audio system! We’ve got this beautiful Aston Martin DB12 Roadster here for a new audio system. We’re adding additional sound deadening throughout the car and are installing Mosconi Pico Amps plus new speakers.

05/23/2026

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!
