Vibe Optisound OS-BMW8V3 8" BMW Underseat Subwoofer – 2 or 4 Ohms

The Vibe Optisound OS-BMW8V3 8" underseat subwoofer is crafted specifically for BMW drivers who want better sound without altering the integrity of their car. Available in both 2-ohm (OS-BMW82V3) and 4-ohm (OS-BMW84V3) versions, this OEM upgrade replaces your factory speaker seamlessly, giving you richer bass and cleaner output—all while maintaining that factory look.

Seamless OEM Integration

Designed to fit neatly under your seat, this subwoofer integrates perfectly with 95% of BMW models from 2005 onwards. There’s no cutting, drilling, or modifying required. It’s a true plug-and-play upgrade that keeps your car’s warranty intact while delivering a big boost in performance.

Engineered for Premium Performance

Vibe didn’t just make another subwoofer—they designed a performance piece. Each Vibe Optisound OS-BMW8V3 uses a Neodymium motor with a new alloy dampening ring, reducing magnetic waste and boosting efficiency. The pressed foam surround, gold-plated terminals, and steel torsion basket work together to produce a strong, distortion-free low end that easily outperforms factory speakers.

Tailored Options for Every BMW System

No matter your BMW’s audio setup, there’s a Vibe Optisound OS-BMW8V3 that fits:

• Base Audio (Post-2019) systems typically use 2-ohm subs. The OS-BMW82V3 model pairs perfectly here, enhancing output and system response.
• Base Audio (Pre-2019) setups benefit from the OS-BMW84V3 4-ohm model, offering a balanced, refined low end.
• HIFI & HK systems get even more from the 2-ohm variant, which extracts the maximum performance from the factory amplifier.

Optimized for Upgrades and Amplifier Compatibility

If you’re running the VIBE POWERBOX65.4BMW amplifier or similar aftermarket DSP setups, both versions of the OS-BMW8V3 are ready to integrate smoothly. The 4-ohm model suits typical amp configurations, while the 2-ohm version is ideal for more advanced systems looking to draw out every watt of available power.

Premium Build for Premium Vehicles

VIBE designed the Optisound OS-BMW8V3 with high-end materials to match the quality of BMW interiors. Every component is engineered to deliver professional-grade bass while keeping weight low and installation simple. It’s not just a replacement—it’s a genuine upgrade in every sense.
