【ONE 130.4｜4-Way Class AB Power Amplifier】

This is a 4-channel, Class AB power amplifier for those who want to add a bit more punch and thickness to the sound of factory audio, and for those who want to clearly drive and separate multiple speakers—such as the front speakers and a subwoofer.

ONE 130.4 supports both high-level and RCA inputs. It can be easily integrated into a system that makes use of the factory navigation and factory audio, allowing you to design the configuration to match the vehicle’s existing setup. Since it also supports power-on via high-level input sensing, it’s an amplifier that’s easy to consider even when you’re planning to combine it with factory audio.

It also supports switching between a high-pass and low-pass filter, so you can make adjustments according to the speakers you connect and your system configuration. Depending on your needs—such as driving the front speakers harder or separating the roles of the front speakers and the subwoofer—you can take advantage of a 4-channel amplifier in a way that fits your setup.

Input sensitivity supports 0.35 to 16V. From factory systems to head units equipped with RCA outputs, it’s designed to make it easier to match the input level to the devices you pair it with. It also supports an optional separately sold remote volume control, so depending on your system configuration, you may be able to adjust the volume from inside the cabin more conveniently.

An amplifier isn’t a product that delivers the same sound just by installing it. How it actually sounds depends on factors such as how you take power and ground, wiring treatment, installation method, pairing with the speakers, and the adjustment of gain and filters. At LOGON, we think together with you so you can end up with a sensible system—confirming the vehicle model and factory audio specifications, your current speaker configuration, the music you usually listen to, and your budget.

If you want to firmly build the foundation of your sound using a 4-channel amplifier, please check your current system and consult us about which part would be most effective to add an amplifier to. We’ll guide you not only with the product itself, but with an approach that considers how you can enjoy music comfortably after installation.
