FRP 緊湊型全頻 D 類單聲道擴大機 12,000 瓦 RMS @ 1 歐姆

The board is genuinely compact for a 12,000-watt amp, which made mounting it under the seat way easier than I expected. It runs clean and stays cool even when I push it hard, though I wish the gain knob had a slightly stiffer feel. For the price, it's a solid buy that delivers.

It does what it says on the box—full-range Class D output is clean enough for my doors—but the 12,000-watt rating is really just marketing; it gets warm fast at higher gains. Still, for the size, it's a decent budget option if you're not pushing it to the limit.
