【ZONOTONE Grandio AC-1 (2.5m)｜Interconnect Cable for Car Audio】

When you want to further refine your car audio sound, one component that’s easy to overlook is the interconnect cable that connects your devices. Because it forms the foundation of the sound, simply swapping the cable can sometimes reveal differences in sound density and fine-grained expression.

Grandio AC-1 is an interconnect cable that combines five materials centered on ultra-high-purity 7N-class Cu: the high-performance pure copper wire HiFC, ultra-high-purity oxygen-free copper wire PCUHD, tin-plated OFC, and ultra-high-purity oxygen-free copper. With ZONOTONE’s distinctive material composition, it preserves powerful character while carefully reproducing the sound’s attack and even subtle details.

For those who want to listen with attention to the smallest nuances in vocals, the texture of instruments, and the depth of the soundstage, it’s an option for raising the overall completion level of your system. It doesn’t just bring the sound forward—it can make the stage feel wider and the sense of energy in performances easier to perceive, aiming for a change that will make you want to listen to your usual songs again.

That said, the impression you get from an interconnect cable can vary depending on the devices you pair it with and the overall direction of your system. I think you’ll have fewer regrets if you confirm your current dissatisfaction with the sound and the sound you want to achieve before choosing, rather than selecting the cable first by itself.

At LOGON, we consider everything together—from how to choose the cable, to connection, wiring handling, and post-installation adjustments—while looking at the equipment you’ll use and how the sound is heard inside your vehicle. Please feel free to consult us in a practical, no-pressure way, including whether your system can truly take advantage of the Grandio AC-1.
