Fabrication for Speaker Enclosures, Dashes, Lighting and More

At Newport Sound, we are dedicated to creating an astounding audio experience. We can fabricate custom speaker enclosures, custom dashes, aftermarket lighting, and more.


We specialize in custom fabrication techniques making custom-sealed, ported, or bandpass boxes for subwoofers to maximize speaker performance. Fiberglass enclosures are the perfect way to customize your sound system. Using fiberglass gives us the freedom to utilize small areas to mount subwoofers or add multiple speakers to a door panel.


Built at a high degree of expertise, all our custom fabrication is done in-house and designed specifically for your vehicle. These are handmade using the finest materials & installation techniques while keeping with the style/lines of your vehicle’s interior. Our skilled design team is dedicated to giving you the highest performance and dependability through outstanding system layout, design & functionality.


From a basic installation to a complete custom car audio installation, Newport Sound in Costa Mesa, CA has you covered.

Custom Enclosures

Custom subwoofer enclosures are created from advanced materials such as fiberglass, marine-grade wood products, automotive-grade plastics, and other rugged composites. We also use steel for mounting provisions and polished aluminum for cosmetic accents. When we design a truly custom subwoofer enclosure, it’s both structurally superior and cosmetically integrated to deliver the highest level of performance and still look like it belongs in your vehicle.


Custom Trunks

We are experts in vented subwoofer enclosure design and tuning and have in-house demonstrations for our clients to easily learn the audible benefits and acoustic efficiencies that a vented enclosure provides over a sealed enclosure.


Custom Panels

We fabricate and install speaker mounting solutions to ensure the most rigid and weather-resistant surface. We fabricate and machine all custom speaker mounts in-house using automotive-grade plastics and composites such as expanded PVC, high-temp ABS, fiberglass, and more. Our goal is to create a mounting solution along with sound-deadening materials to provide maximum speaker performance so the sound reaches your ears and isn’t wasted vibrating other panels and parts in the process.
