Total Power 12.6 @ 2 Ohms: 4 x 500 WRMS and Total Power 12.6 @ 4 Ohms: 4 x 300 WRMS. Do not use an impedance load lower than the amplifier specification. This can damage the equipment. Use wire solder for tinning the cable end for better electrical contact. Loose electrical connections can cause malfunction, heating and even fire. The GND connection must be as short as possible, using an adequate wire terminal firmly connected to a clean, paint-free spot at the car chassis. It allows you to adjust the Crossover by the selector key: LOW, FLAT e HIGH.
