Compact Power. Pure Focal Sound.

The Focal ISUB ACTIVE is a compact amplified subwoofer designed to bring powerful, dynamic bass to any factory audio system without compromising interior space.
Built on Focal’s decades of acoustic innovation, it combines precision-engineered power, ease of integration, and discreet design — transforming your in-car listening experience with deep, controlled low frequencies.

With its built-in 260-watt amplifier and Plug & Play ISO connectivity, the ISUB ACTIVE is the ultimate “no-cut” bass upgrade for modern vehicles.


Powerful, Controlled Bass

This active subwoofer delivers rich, punchy bass that elevates every track — perfectly complementing your existing speakers.
Thanks to its high-efficiency Class D amplification, the ISUB ACTIVE produces clean, distortion-free low-end response while preserving full dynamics and detail.
The result: a seamless and powerful soundstage, engineered for everyday driving and high-fidelity enjoyment.


Effortless Installation

Designed for universal integration, the ISUB ACTIVE connects directly to your factory head unit using the supplied Plug & Play ISO harness — no cutting, splicing, or complex wiring required.
Its ultra-compact enclosure makes it easy to position under a seat, behind trim, or in the boot — ideal for discreet installation in any vehicle.


Tuned for Your System

With a range of user-adjustable settings, including input sensitivity, low-pass crossover, and volume boost, you can fine-tune the ISUB ACTIVE to match your vehicle’s acoustics and your personal sound preferences.
This level of control ensures perfectly balanced integration with your existing front and rear speakers — for bass that feels natural, not overpowering.


Upgrade Without Compromise

The ISUB ACTIVE lets you experience deep, accurate bass without losing cabin space or altering your vehicle’s original look.
Whether you’re enhancing a standard system or complementing Focal Inside speaker kits, it’s the perfect finishing touch for balanced, high-impact sound.

Focal ISUB ACTIVE – Feel the Drive. Hear the Difference.
