The Sp Audio SP-1200.4D car amplifier is a four-channel Class D model with RMS output power that depends on speaker impedance and wiring configuration. At 14.4 V, it delivers 4 × 1,200 W at 1 Ω, 4 × 600 W at 2 Ω, and 4 × 400 W at 4 Ω. In bridged mode, the output power is 2 × 2,400 W at 2 Ω and 2 × 5,800 W at 4 Ω.
It features high-pass and low-pass filters, bass boost adjustment, and an intelligent cooling system. Protection features cover output short circuits, high or low supply voltage, and overheating.
