This one was a fun project.
This mint-condition blue Chevy Silverado square body is a true survivor. It’s a single-owner truck, and being a diesel makes it even harder to find one this clean. When a vehicle has been cared for this well, you don’t just start cutting things up. Every part of this install was planned to keep the truck looking as original as possible.
The owner wasn’t after a loud system with a bunch of bass. He just wanted to enjoy his music more and hear all the little details that get lost in an older vehicle.
One of the biggest upgrades wasn’t even the speakers—it was making the truck quieter. We covered just about everything with SoundSkins sound treatment: the roof, floor, firewall, rear wall, doors, and both the inner and outer door skins. Less road noise, fewer rattles, and a much better environment for the speakers to do their job.
For the source, we went with Sony’s XAV-AX6000. It’s one of our favorite radios thanks to its super-responsive glass capacitive touchscreen and simple, clean interface. Since the factory dash only accepts the original single-DIN radio, we ordered a replacement dash bezel designed for a double-DIN unit like the Sony. The catch? It only came in black. To keep the interior looking as factory as possible, we custom dyed the bezel to match the original blue dash. After a lot of time dialing in the color, it came out looking like it belonged there from the factory.
From there, everything feeds into a Helix V Eight DSP Ultimate, giving us complete control over every speaker in the truck.
To keep everything looking factory, we designed and 3D printed all of the speaker adapters in-house. Up front, we installed Helix Compose i7 tweeters and i7 W165 woofers in the factory locations, and in the rear C-pillars we used Helix Compose 4x6 speakers so everything stayed right where Chevy intended.
The end result is exactly what we were after. It still looks like the same classic square body on the inside, but it’s a whole different experience behind the wheel. Quieter, cleaner, and packed with detail—without adding a single subwoofer.
Sometimes the best upgrades are the ones that look like they were always supposed to be there.
