【AV due 2ch Power Amplifier｜Car Audio Amplifier That Brings Out the Musicality of the VOCE Series】

Even if you turn up the volume of your car audio, the sound may feel thin, the bass may not stay steady, and the vocals may not come forward. To address issues like these, there’s a way to drive the music signal properly—not just by replacing the speakers.

AV due is a 2-channel power amplifier developed based on the design philosophy adopted in the VOCE series. It supports 260W × 2ch at 4Ω stereo and 450W × 2ch at 2Ω stereo, with enough headroom to drive your speakers.

Adding an amplifier doesn’t simply make the sound louder. It also makes the sound’s attack and fine details easier to bring out, and it becomes easier to organize the spatial relationships between vocals and instruments. You may even feel a change in familiar music—hearing sounds you never paid attention to before, coming naturally into your ears.

In addition to stereo connection, AV due can also be used in a 4Ω bridged connection as 900W × 1ch. Of course, it can be used as an amplifier for the front speakers, and depending on your system configuration, it can also be used as a subwoofer amplifier—allowing further customization based on your vehicle and speaker combinations.

It also features built-in high-pass and low-pass crossover functions, supporting band-splitting tailored to your system. If you’re adding it to an existing car audio system, it’s important to determine where to integrate AV due while checking how signals connect with the factory navigation, DSP, and speakers.

Even with the same amplifier, the final result varies depending on how power and grounding are handled, wiring treatment, installation method, and how it’s paired with your speakers. If it were me, I wouldn’t decide based on the amplifier’s standalone performance alone. I’d confirm your current system, the music you usually listen to, and the sound you want to achieve—then plan the configuration.

For those who want “to make the factory system a little more powerful,” “to take full advantage of the speakers’ performance,” or “to fine-tune the sound in the future even including a subwoofer,” this is a power amplifier that’s easy to consider. Since the best connection method changes depending on the vehicle model and your current system, let’s decide the direction together while checking on the actual car.
