1967 Chevy Impala back to life with a full custom audio setup that keeps the classic feel while delivering a whole new level of sound.

This build features Alpine S2-S40 4” coaxials, Cicada 6x9 pro audio coax drivers in custom fabricated kick panels, and a 5.25” coaxial Alpine S2-S50 in the rear center location to help fill the cabin evenly. For low end, we built a custom enclosure for two JL Audio 10W3 subwoofers firing into the cab to maximize output while keeping as much usable space as possible.

We also fabricated a custom amp rack on the passenger side housing two AudioControl Altitude A600.4 amplifiers and one AudioControl Altitude A1500.1 to power the subs, along with an Epicenter Micro to bring the system to life. To keep the vintage look intact, we custom integrated a Bluetooth module into the factory radio so volume can still be controlled right from the original k***s.

Classic car, modern sound, clean integration. Built with detail from start to finish by us your car audio professionals, Audio Systems in Montclair, CA.

Clean, simple, and done right 🔊

This 1995 Porsche 928 GTS came in for a full audio refresh, and the goal was to keep everything looking factory while upgrading the sound across the board.

We installed AudioControl PNW speakers all around for a clean, balanced sound, paired with a compact Diamond Audio 5-channel amp to keep everything powered without taking up space.

For bass, we built a custom 11” enclosure hidden in the factory spare tire location — completely out of sight, but adds the perfect low end to the system.

To finish it off, we added the Porsche PCCM radio, bringing in modern features while keeping that OEM Porsche look and feel.

Simple, clean, and exactly how it should be:
• Factory look
• Modern functionality
• Full, balanced sound

2023 Ford Shelby Centennial edition, all complete from Oregon! This was a very big project, but at the end of the day it sounded fantastic and looked it too!

In the audio, we built two systems the interior system with Cicada Pro Audio all around, powered by the new FLX amplifiers ( ). For integration the PAC-Audio AP4-FD31 going digital into the Helix DSP3.S ( ). Lastly on bass duty we have two JL Audio 10TW3 ported, without a seat lift and it sounds very good!

Part 2 of the audio is now the exterior system which is independent and has its own battery for tailgate parties. We did two set of 6.5 Cicada Pro Coaxials, and 2 10” Pro Midbasses from Cicada powered with the same FLX amplifiers used in the rear setup. For our source a WS-MC-2 was used, great unit with clean output. Addressable RGBs were used to light up the etched acrylic to give a great dancing RGB effect. A NOCO charger was added to keep this system ready at all times.

Extra modifications done to the truck included the following. Motorized tonneau cover, interior lighting package (adressable), starlight headliner, custom fabricated bracket for secondary, custom bracket to mount rear enclosure without making new holes, sound treatments.
