Item dimensions L x W x H 7.87 x 6.9 x 2 inches Manufacturer AUDIOZERONE Maximum Supply Voltage 16 Volts Minimum Supply Voltage 10 Volts (DC) Mounting Type Surface Mount Power - 1000 Watts MAX x 1 @1-Ohm, 500 Watts RMS x 1 @1-Ohm, 350 Watts RMS x 1 @2-Ohms,000 Watts RMS x 1 @4-Ohms Class D - Power loss is significantly reduced making the amplifier highly efficient. Excess energy is stored until it’s needed instead of being converted into heat. Reduction in size/weight, reduced power waste, smaller heat sink, compact circuitry 1 Ohm Stable - Able to continuously power loads of 1 Ohm without encountering difficulties such as overheating. Typically made to power up subwoofers that demand the heavier power load requirements to be able to perform the way t
