The VIBE OptiSound BMW Kit is a complete plug-and-play component speaker upgrade designed for selected BMW vehicles. The kit includes a 4-inch component speaker system and 8-inch underseat subwoofers, using car-specific baskets and harnesses for easier installation.

Designed to improve clarity and bass response over factory speakers, this system can be used as a passive or semi-active setup. The included crossover uses a reference curve setup, making it suitable for drivers looking for a more refined and balanced sound upgrade.

This kit is intended for compatible BMW 1 Series and 3 Series models and can be paired with a suitable amplifier for increased output and performance.
