2026 GMC Denali Ultimate Bose Sound System Walkthrough! 🔥 Part (1/2)

We just finished up this 2026 GMC Denali Ultimate, so I wanted to give you guys a full walkthrough of the system and explain exactly what we did and why.

Instead of immediately replacing all 12 factory Bose speakers, we kept them and re amplified the entire system using a Helix V Twelve DSP amplifier. This gives us more power to the factory speakers while also giving us full control over the EQ, time alignment, crossovers, and tuning through the Helix DSP.

After tuning everything with our measurement microphone, the difference over the factory system was huge. Better sound stage, much better equalization, and significantly cleaner output when you start turning the volume up.

For the low end, we installed our Stage 1 GM under seat enclosure loaded with (2) full size Helix IQ 12’s powered by a Wavtech link1500.1. The enclosure keeps a clean OEM+ look underneath the rear seat, but these subs still have plenty of output when you want to turn it up.

We also 3D scanned and modeled parts of the truck to design our own custom fit Helix Conductor mount and a bolt in fuse block mount, keeping everything secure and looking like it belongs there.

The nice thing about building the system this way is that the client now has a really solid foundation. If he wants to take it further down the road, we can replace the factory speakers with higher end speakers, retune the DSP, and get even more clean output without having to redo the entire system.

In this video I walk through the complete setup, show where everything is installed, and explain how it all works together.

2024 Ford F-250 Platinum In The Shop For A B&O Sound System Upgrade!

We’ve got this 2024 F-250 Platinum in the shop for a complete front to back sound system upgrade using equipment from , , and !

Up front, we’re installing Helix i5 8” midbass drivers in the factory doors, along with Helix i5 midrange speakers and tweeters to build a full 3 way front stage. In the rear, we’re upgrading to Helix i3 6.5” coaxials, all powered and controlled by a Helix V Twelve DSP amplifier.

We’re also doing full sound treatment to all four doors and the back wall using BlackHole products to reduce resonance, improve midbass performance, and get the most out of the new speakers.

For bass, we’re building one of our custom Stage 2 under seat enclosures loaded with (3) Thin Pro 10’s powered by an Audio Dynamics X3K.1 3000W amplifier. This setup should deliver plenty of clean output without a seatlift!

Everything will be integrated through a NAV TV ZEN preamp, along with our custom bolt in amplifier rack and plug and play wiring to retain factory functionality without cutting into the original wiring.

Once everything is installed, we’ll tune the entire system using our measurement equipment and Helix DSP software to dial in the EQ, crossovers, levels, and time alignment.

The goal is a complete OEM+ system with plenty of output, excellent sound quality, and an installation that looks like it belongs in the truck.

Stay tuned as we work through this build!

2025 Chevy Silverado Full Helix Sound System Upgrade!

We just finished up this 2025 Silverado RST, and this is a perfect example of how much you can improve the sound quality in these trucks while maintaining a clean OEM+ appearance.

This truck originally came to us for one of our Stage 2 Plug & Play subwoofer packages with (2) Wāvtech Thin Pro 12’s powered by a Wāvtech link1500.1. The client loved the bass, so we brought it back to upgrade the entire front and rear speaker system to match.

Up front, we installed a full 3 way Helix system using i5 8” midbass drivers in the doors, i5 M50 widebands in the dash, and i5 T25 tweeters mounted on the A pillars. In the rear, we installed i3 6.5” coaxials, all powered and controlled by a Helix V Eight DSP amplifier.

We also completed full sound treatment throughout the truck, 3D scanned and printed custom A pillar tweeter mounts, and designed a custom Helix Conductor controller mount that drops directly into the center console with matching black upholstery.

Everything is integrated using a NAV TV ZEN AVB GM, custom bolt in amplifier rack, and plug and play connections to retain factory functionality without cutting into the original wiring.

Once installed, we tuned the entire system using our measurement microphone and Helix DSP software to dial in the EQ, crossovers, levels, and time alignment. The improvement in soundstage, clarity, separation, and clean output was huge.

The goal with this build was very simple… make everything look and function like it came from the factory while delivering an awesome listening experience!
