【MINI-150.4｜Power Amplifier for Compact, High-Quality Sound】

A compact power amplifier designed for those who want a bit more impact and cohesion from their factory audio, or who want to improve sound quality by adding an amplifier in limited space.

MINI-150.4 is engineered to deliver musically satisfying playback while keeping power consumption in check with Class D operation. Using premium coils and minimizing DC resistance as much as possible, it’s also mindful of sound attack and control in the low frequencies.

Changes in frequency response due to load impedance are kept to 0.007% or less, making it an amplifier that helps you feel better sound cohesion and listenability not only when you turn the volume up, but also at everyday listening levels. It’s also suitable for those who want vocals and instrument sounds to come across more naturally, or who want to bring out the best characteristics of their speakers.

Its appeal also includes a specification aimed at suppressing external noise intrusion, along with a compact body measuring 183(W) × 50(H) × 146(D) mm. Even when installation space in the vehicle is limited, it fits into a size that’s easy to integrate while still considering other equipment and trunk usability.

It’s important not just to add an amplifier, but to consider where adjustments will likely have the biggest impact—taking into account the vehicle’s factory system, your current speakers, and your sound preferences. At LOGON, we pay close attention to wiring and installation methods, then finalize the setup by actually checking the sound inside the vehicle after installation.

If you’re considering adding an amplifier but aren’t sure which equipment to choose, let’s confirm your current system first and decide on the direction together.
