We recently had the pleasure of customizing a sleek Regal 1900 ESX boat, turning it into a true head-turner on the water. With Storm Gray over Cool Gray SeaDek and a premium JL Audio marine sound system, this boat brings comfort, style, and killer sound in one smooth package.

SeaDek: Storm Gray Over Cool Gray
Comfort and traction meet high-end design with custom SeaDek flooring throughout the boat. The Storm Gray over Cool Gray color combo perfectly complements the boat’s style while offering a non-slip, cushioned surface that keeps things safe and comfortable for all your water adventures. It’s UV-resistant, easy to clean, and built to last.






🔊 JL Audio Marine Speakers and Fusion Radio with Rear Remote
What’s a day on the water without some music? We upgraded this Regal with JL Audio marine-grade speakers, designed to cut through wind and waves with clean, powerful sound. Whether cruising or anchored on the shore with friends, these speakers bring the perfect soundtrack to every moment. On the rear of the boat, a Fusion remote was installed to give extended control to the new Fusion (by Garmin) radio unit at the drivers seat.

At Next Level Car Audio, we love a challenge. When a Ferrari Portofino rolled into our shop, we knew this installation would be nothing short of precision craftsmanship. The project? A custom Alpine Electronics stereo upgrade and a K40 Electronics speed ticket protection system seamlessly integrated into the front and rear bumpers.

Precision Meets Performance
Ferrari vehicles are engineered for performance and elegance, which means every modification must match their high standards. Installing a custom stereo system in the Portofino required extreme attention to detail. Alpine Electronics provided the perfect high-fidelity sound solution, enhancing the driving experience without compromising the factory design.







Our team carefully designed and fitted the Alpine system, ensuring:
✅ Crystal-clear sound at high speeds
✅ Custom fabrication for a seamless fit
✅ Minimal weight impact to maintain Ferrari’s performance
The results? A sound experience that complements the thrill of driving this Italian masterpiece.
Seamless Wireless Phone Charging Integration
Convenience is key in any modern vehicle, so we went a step further by installing a wireless phone charging pad under the dash, perfectly positioned between the driver and passenger seats.




This addition allows for:
⚡ Effortless charging—no more tangled cords
⚡ Discreet placement—hidden yet accessible
⚡ OEM-style integration that blends with the Portofino’s interior
This premium convenience feature ensures the driver stays powered up without compromising the Ferrari’s clean interior design.
The Ultimate Speed Ticket Protection: K40 Electronics
No high-performance vehicle is complete without the right protection on the road. We installed a K40 Electronics speed ticket protection system, one of the most advanced radar and laser defense systems available. This required precise mounting in the front and rear bumpers to ensure maximum coverage.




K40’s advanced technology provides:
🔵 Full 360-degree radar detection
🔵 Custom alerts for hidden speed traps
🔵 Stealth installation with no visible components

Notice in the picture above that the you can notice the parking sensors, but with a closer look you can barley spot the 3 laser diffusers. By integrating the K40 system flawlessly, we kept the Ferrari’s sleek design intact while offering the owner peace of mind on every drive.

Alpine R-Series Subwoofers: Setting the Stage for Sonic Brilliance
To infuse the Challenger’s interior with heart-pounding audio, we turned to the Alpine R-Series 10-inch subwoofers. Renowned for their exceptional sound quality and performance, these subwoofers are designed to reproduce deep, impactful bass that adds a new dimension to the listening experience.
The choice of the Alpine R-Series was not just about enhancing the bass; it was about creating a symphony that resonates perfectly with the car’s character. These subwoofers excel in delivering accurate and clear bass notes, ensuring that the music remains detailed and dynamic even at high volumes.
We fitted this Dodge Challenger with some all new Alpine subwoofers, and a custom built subwoofer enclosure!

Crafting Excellence: Custom Subwoofer Enclosure
To harness the full potential of the Alpine R-Series subwoofers, we embarked on the creation of a custom-fitted and built subwoofer enclosure. This step was crucial to achieving the best possible audio performance while maintaining the Challenger’s interior aesthetics.
- Design and Measurements: Our team meticulously measured the available space in the trunk and carefully designed an enclosure that optimized both air volume and subwoofer positioning. The enclosure’s design was not only functional but also tailored to blend seamlessly with the Challenger’s interior design.
- Precision Fabrication: Crafting the enclosure required precision fabrication to ensure a perfect fit. We used high-quality materials that not only enhanced audio quality but also ensured the enclosure’s durability and longevity.
- Integration and Aesthetics: The custom enclosure was designed to look like an integral part of the trunk, showcasing our commitment to preserving the Challenger’s visual appeal. It seamlessly merged with the existing design, proving that audio enhancements can be both impressive and subtle.
Alpine Series R 10“ Subwoofers


The Sonic Symphony Unleashed
Once the Alpine R-Series subwoofers and custom enclosure were seamlessly integrated into the purple Dodge Challenger, it was time for the moment of truth. With the audio system calibrated and tuned to perfection, the Challenger’s interior was transformed into an acoustic wonderland. The deep, resonant bass notes combined with the powerful engine’s roar, creating a symphony that resonated not only in the ears but in the soul of the driver.
