Eton PA 1 擴大機 單聲道 D類 1聲道 超低音喇叭擴大機 最高480W RMS

Plugs into a tight space under my truck seat without overheating, which was my main worry. The 480w RMS output is more than enough to push my 12-inch sub clean and punchy.

I was skeptical a mono block this small could push my sub properly, but the Class-D efficiency means it runs cool all day and delivers that full 480 watts without breaking a sweat. The compact size made mounting it behind my seat incredibly easy.

Tiny footprint, massive punch—this thing drives my sub like it’s twice its size, and the Class-D efficiency means it barely warms up even after an hour of heavy bass. Fit it under the seat with room to spare, and the 480W RMS is honest power, not inflated numbers.
