Helix U 8A (Active Subwoofer)

HELIX U 8A – Compact Active Subwoofer with Powerful Bass

When space is limited but bass performance is essential, the HELIX U 8A active subwoofer is the ideal choice. Equipped with a powerful integrated Class AB amplifier (180 W RMS) and a heavy-duty 8” aluminum cone driver, it transforms amplifier power into tight, punchy bass with precision and detail.

The diecast aluminum housing ensures low-resonance operation and optimum heat dissipation, while the shallow cabinet design allows flexible installation – even under car seats. With extensive adjustment options including a continuously adjustable lowpass filter, sensitive phase control, and subsonic filter, the bass output can be perfectly tailored to any vehicle’s acoustics.

Thanks to multiple input options – RCA, high-level inputs with auto turn-on, and remote control integration – the HELIX U 8A easily integrates into factory or aftermarket audio systems. For drivers who want extra low-end kick without sacrificing space, this subwoofer is a true game-changer.
