【PRO 4/10 Power Amplifier｜High-Quality Sound with Low Distortion and a Beautiful Aluminum Design】

The power amplifier I recommend if you want to fine-tune your car audio sound to be even more natural and detailed is PRO 4/10.

It has a track record of being selected as an EISA Best Product, and it was also highly praised by CAR＆HiFi magazine. Using the technologies cultivated over time, it reproduces musical signals with minimal distortion. You’ll be able to hear more calmly—even details you may not have noticed before, such as subtle vocal expressions and the timbre of instruments.

Adding an amplifier doesn’t simply make the volume louder. By installing it while taking into account how it pairs with your factory system and the speakers you’re currently using, you’ll see changes in sound thickness, headroom, and overall listenability. One reason to choose a power amplifier is that you can enjoy the music you always listen to even when you keep the volume slightly lower.

Its design is also appealing: it combines curved aluminum with a perforated plate. It’s finished in such a way that it feels like a shame to hide it away in an area you can’t see—so you can also enjoy the pleasure of owning it.

That said, you’ll generally be more satisfied with the result if you consider the amplifier not as a standalone product, but together with your vehicle’s factory system, speakers, power supply, and installation method. At LOGON, we propose a reasonable configuration while confirming your vehicle model, your current audio concerns, the music you often listen to, and the sound you want to achieve.

Even with the same amplifier, the final result varies depending on how the power and wiring are handled, the installation method, and how it’s combined with the entire system. If you’re interested in the PRO 4/10, let’s organize the direction together— including whether it will suit your current system.
