GZCS 20SUB-ACT & GZCS 25SUB-ACT
Two compact Ground Zero active subwoofers, 20 cm (8") and 25 cm (10"), designed to add real bass to your system without sacrificing space in your vehicle.
An excellent solution for enhancing everyday bass
With the GZCS 20SUB-ACT and GZCS 25SUB-ACT, Ground Zero offers two active subwoofers that are particularly attractive for everyday installations. With an integrated amplifier, a compact enclosure, and two subwoofer sizes, you can choose between the 20 cm (8") model for tight spaces and the 25 cm (10") model for more impact and depth in the low frequencies.
Two sizes to suit your vehicle
GZCS 20SUB-ACT
The GZCS 20SUB-ACT is particularly attractive when available space is limited. Its 20 cm (8") subwoofer provides a real bass boost while maintaining a compact and discreet installation.

GZCS 25SUB-ACT
The GZCS 25SUB-ACT maintains a very contained footprint while upgrading to a 25 cm (10") subwoofer. In our opinion, it is the best compromise for a standard vehicle when you want more impact and depth in the bass without installing a large traditional enclosure.

- 430 W maximum power

The Ground Zero GZCS 25SUB-ACT presented by AutoNews
The Ground Zero GZCS 25SUB-ACT was also the subject of a dedicated article in AutoNews' audio section. This is valuable exposure for this 25 cm (10") active subwoofer, which relies on a compact, all-in-one design.
The model pairs a 25 cm (10") subwoofer with its integrated amplification. This architecture makes it possible to add a genuine bass boost to a vehicle without having to separately install a passive subwoofer and a dedicated amplifier.
To us, the GZCS 25SUB-ACT offers an excellent balance between price, size, and performance. Its 25 cm (10") subwoofer provides enough membrane surface to achieve generous bass, while remaining easy to integrate into an everyday vehicle. It isn't intended to replace a large SPL setup: its benefit is to provide real bass while remaining compact, simple to install, and easy to adjust.
Which Ground Zero GZCS should you choose for your vehicle?
The GZCS 20SUB-ACT is particularly well-suited for vehicles with limited interior or available cargo space. It is an excellent choice for a van, a utility vehicle, a small city car, or more generally any vehicle where every centimeter counts.
Its compact format provides a real bass boost without unnecessarily cluttering the cabin or loading area. It is therefore particularly attractive for professionals who use their utility vehicle daily but still wish to enjoy an audio system with more bass.
For a standard-sized vehicle, the GZCS 25SUB-ACT is generally the most interesting choice. Its 25 cm (10") subwoofer allows for more impact and depth in the bass than the 20 cm (8") model.
It is perfect for hatchbacks, sedans, wagons, SUVs, and minivans. Despite its larger speaker, the enclosure remains remarkably compact at only 16 cm in height, allowing you to retain most of the available space in the trunk.
The right compromise for an everyday system
No need to add a separate subwoofer amplifier. The enclosure incorporates its own amplification to simplify installation.
At only 16 cm in height, the GZCS series is designed to add bass while preserving as much space as possible in the vehicle.
The 20 cm (8") is particularly suited for vans, utility vehicles, small cars, and cramped interiors. The 25 cm (10") is better for standard vehicles seeking more bass impact.
A complete solution for adding a real subwoofer and its amplification without multiplying components, space usage, and installation budget.
Bass tailored to your vehicle
Choose the 20 cm (8") Ground Zero GZCS 20SUB-ACT for a van, utility vehicle, small car, or limited space, or upgrade to the 25 cm (10") GZCS 25SUB-ACT for a standard vehicle and more generous bass.
