FRP 緊湊型4聲道全頻Class-D擴大機 | 1200W RMS

Wired this compact 4-channel into my truck's system and it pushes all four speakers clean at high volume without any distortion. The Class-D design means it barely takes up space under the seat, which is exactly what I needed.

Wasn't sure a Class-D this small could push my door speakers and a sub, but it does it without breaking a sweat. Runs warm but never shut down on a long drive, so one star off for that.

Runs cool even after an hour of driving all four speakers hard, which I didn't expect from something this small. Only gripe is the mounting screws are cheap and I swapped them out. For the size and the 1200W rating, it's hard to beat.
