【Heritage bi-one｜Quattro Trigo’s AB-Class Car Audio Amplifier】

I want a little more thickness and presence in my car audio sound. I’d like to enjoy the expressions of vocals and instruments calmly and slowly. If that sounds like you, consider Heritage bi-one from Italian manufacturer Quattro Trigo.

Built with an appreciation for the musicality unique to AB-class operation, this amplifier is ideal not just for making the sound louder, but for creating a system that lets you enjoy your usual music more carefully. It’s recommended for those who want to savor the subtle nuances within familiar songs—such as the voice of the vocalist and the overlapping tones of instruments.

The Heritage series is designed with care not only for sound quality, but also for the premium feel of the main unit itself. After it’s installed in your vehicle, you still want the unseen parts to be finished properly. I think this amplifier delivers on that kind of commitment to car audio.

An amplifier won’t produce the same sound just because it’s installed. It’s important to plan the installation with the right considerations—such as the combinations with speakers and subwoofers, the routing of power and wiring, and how the sound comes together in the cabin. At LOGON, we work together to design the configuration and tuning that will bring out the best in the Heritage bi-one, while confirming your vehicle, your current system, and the direction of music you want to enjoy.

If you want to go one step further and deepen the time you spend enjoying music in your car—without compromising on either appearance or sound—please feel free to consult us. We’ll guide you in a reasonable way, including what kind of sound you want to aim for after installation, not just the product itself.
