Every footwell sub we make is unique to the car it’s being installed in. This Mazda CX50 threw us some curveballs but nothing we can’t handle. Check out the custom fabricated footwell sub box and stay tuned to see how it all sounds 🎶

As usual, it was a little bit of everything at Sound in Motion. While a client picked up their Ferrari with a new audio system, they dropped off this Porsche Cayenne Turbo S for radar/laser protection and audio upgrades. Then we had:
— A Honda Fit getting a new SONY head unit and backup camera
— A Mercedes S439 receiving a fold-out Pioneer Electronics (USA) Inc. head unit and backup camera
— This Lexus IS350 getting a full custom audio makeover with new speakers
— A RennTech-tuned CLS63 AMG leaving us with Apple CarPlay

This Mustang RTR was already 1 of 1 with its mystichrome paint but our team made it even more unique with a custom audio system. Fitted with our famous footwell sub, new speakers, and Mosconi amps, one thing is guaranteed; if you don’t hear the V8, you’ll hear the music.

What better way to start the week than with this stunning highly optioned Ferrari F8 Spyder. After doing a custom audio systems in this clients Ferrari 488 and 296GT, this newly purchased F8 is here for an audio overhaul and radar/laser protection.

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!

06/27/2026

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!
