【AV uno｜High-Power 1ch Power Amplifier】

You want your subwoofer to hit properly—but you don’t just want to turn up the volume. You also want to care about the thickness of the low end and the cohesiveness of the sound. If that sounds like you, AV uno is worth considering.

This 1-channel power amplifier delivers 700W at 4Ω and 1200W at 2Ω. By pairing it with large-diameter subwoofers or a system aiming for more comfortable low-end reproduction, it powerfully supports the bass that forms the foundation of music. It’s ideal for those who want to add solid energy to the areas that previously felt a bit lacking—such as the presence of a kick drum and the weight/thickness of the bass.

The low-pass filter can be adjusted from 50Hz to 500Hz, with a slope of 24dB. It’s also a key point that, while considering the connection with the front speakers, you can dial it in to a natural balance where only the bass doesn’t become overly prominent. A subwoofer’s final sound depends not only on the amplifier output, but also on the crossover settings, mounting method, and how it sounds inside the vehicle.

If it were me, I wouldn’t choose the AV uno as a standalone unit. I’d check the subwoofer you plan to use, your current system, and even how loud you listen—then build the combination accordingly. To take full advantage of the amplifier’s power, it’s important to consider the power supply, wiring, installation method, and the final sound tuning as well. Let’s think together about a configuration that lets you enjoy great sound comfortably, matched to your vehicle model and system.
