【ＡＴＯＭＯ 4｜Compact 4-Channel Power Amplifier That Makes Use of OEM Audio】

If you want a bit more punch from your OEM audio sound, and speaker replacement alone doesn’t feel enough, then ＡＴＯＭＯ 4 is what you should consider.

Despite its compact body, it supports 4-channel output. It’s easy to fit even in limited space inside the vehicle and is well suited for system upgrades based on OEM audio. It’s a convenient amplifier when you want to strengthen the foundation of the sound without making large-scale changes to your current setup—while keeping the same everyday usability.

Because you can switch between Hi input and Low input, you can decide on the connection method to match your vehicle’s audio configuration. However, simply adding an amplifier won’t produce the same kind of sound automatically. By tuning everything—including compatibility with the speakers, gain settings, installation method, and wiring—you can make it easier to take full advantage of the strengths of the ＡＴＯＭＯ 4.

At Logon, we first confirm your vehicle model and the specifications of your OEM audio, as well as your current system and sound preferences. Then, we work with you to determine whether you should add only an amplifier or combine it with a speaker replacement. If you’d like to enjoy changes in sound in a compact setup, please consult us while checking the condition of your current vehicle first.
