I installed this Stealthbox in my 2026 Chevrolet Silverado Crew Cab as part of a complete JL Audio system upgrade, and it exceeded my expectations.
The fit and finish are outstanding. It integrates perfectly under the rear seat and looks like it came from the factory. The enclosure is extremely well built and makes excellent use of otherwise unused space without sacrificing rear-seat functionality or storage.
What really impressed me is how well the Stealthbox performs. The bass is deep, clean, accurate, and effortless. It delivers serious low-end impact when the music calls for it, but it never sounds boomy or overwhelming. Instead, it blends seamlessly with the rest of the system and enhances the entire listening experience.
For those considering this enclosure, here is the system I paired it with:
JL Audio RD900/5 amplifier
JL Audio RD1000/1 amplifier
JL Audio C2-650 component speakers (front)
JL Audio C2-650X coaxial speakers (rear)
PAC AmpPRO AP4-GM71 integration module
JL Audio 1/0 OFC power distribution system
Sound-deadened doors
TEN87 Design block-off plates
TEN87 Design amplifier rack
The result is a system that sounds incredibly balanced. Vocals are clear and up front, midbass is tight and punchy, and the Stealthbox provides the foundation that brings everything together. Even at higher volumes, the system remains clean, controlled, and musical.
I considered custom enclosures and other prefab options before choosing the JL Audio Stealthbox. While it is certainly an investment, the engineering, fitment, and performance justify the cost. The fact that it preserves the factory appearance and functionality of the truck while delivering this level of performance makes it even more impressive.
If you're building a premium Silverado or Sierra audio system and want powerful, audiophile-quality bass without sacrificing cabin space, this Stealthbox is the benchmark.
Highly recommended.
