【ONE 130.4 DSP | 4ch AB-class amplifier + amplifier with 6ch DSP】

You want to fine-tune the sound of your factory audio a little more. You replaced the speakers, but when you listen in the car, the sound feels like it’s not coming together properly. If that sounds like you, the ONE 130.4 DSP is for you.

It integrates a high-quality 4-channel AB-class amplifier with a 6-channel DSP. While sending plenty of power to your speakers, you can precisely adjust the sound balance to match your in-car environment.

You can fine-tune not only the volume, but also how well the sound “blends”

Car audio doesn’t always become ideal just by replacing the speakers. Since the distance between the driver’s seat and the speakers differs left to right, you need in-car adjustments unique to your setup—such as vocal positioning and the way the bass connects.

With the ONE 130.4 DSP, you can make settings like the following using a computer:

• Equalizer
• Crossover
• Time alignment
• Adjusting the volume balance of each channel

Based on the sound of your factory audio, while leveraging the speakers’ character, you can make vocals easier to hear and smooth out the connection of the low end. Even with songs you listen to all the time, you may feel that the way the sound comes out changes.

Also ideal for upgrading a system while keeping your factory audio

Because it supports high-level input, it’s a model that makes it easier to consider a system upgrade while keeping your factory audio.

It also includes pre-outs, so the configuration is designed to be easy to expand in the future—for example, if you want to combine it with another amplifier or a subwoofer. You can also add a remote volume option.

However, even if you install the same amplifier, the final result will vary depending on the vehicle model, the factory system, and your combination of speakers. It’s important to think not only about wiring methods and mounting locations, but also about the final DSP adjustments.

At LOGON, we help you think through whether adding the ONE 130.4 DSP actually makes sense for you, after confirming how you use your car, what music you usually listen to, and your current audio setup. If it were me, I wouldn’t decide based on the product alone—I’d determine the configuration by considering the balance with your speakers and subwoofer(s).

Whether you want to truly enjoy the changes in sound or you want to upgrade the system without forcing it while keeping your factory audio—please feel free to consult us. Let’s sort out practical ways to get you listening to music in a way that feels great in your car.
