Pioneer GM-D9704 立體聲擴大機 緊湊型4聲道 FD類 800W RMS

Fits perfectly behind the seat without crowding, and the 800 watts RMS really wakes up my door speakers. The Class-FD design runs surprisingly cool even during long drives.

Was a bit skeptical about the power given the small size, but this amp easily runs my door speakers and a sub without any distortion. I love that I could mount it vertically behind the rear seat, saving tons of floor space.

Tucked this under the seat without losing any legroom, and the 800w RMS rating is no joke—it drives my door speakers clean and punchy. The Class-D efficiency means it barely gets warm even after an hour of highway listening, which is a huge plus for a compact build like mine.
