Ground Zero GZRA 700.1-MICRO 1チャンネル クラスD アンプ

For such a tiny amp, the Class D efficiency is unreal—it barely sips power but drives my sub like it’s twice its size. Fits flush under the seat with room to spare, and the bass stays clean even at low volume. Exactly what I needed for a stealth install.

Installed this in my hatchback and was surprised how much bass it pushes for its size. The class D efficiency means I barely notice it on my electrical system.

Fits under the seat of my pickup with room to spare, and the Class D efficiency means it sips power while still shaking the mirrors on bass-heavy tracks. Was a bit skeptical about the size-to-output ratio, but it handles my sub with way more authority than amps twice its size.
