1 x 2000 Watts RMS @ .5 O Class D AmplifierNew heatsink design! More power and reliability!Extreme engineering from extreme power! • Ultra-Efficient Class D topology reaching 83% efficiencies at full power, provides the biggest power in the smaller chassis.• SMT assembly and 1% resistors round out a proven Power-House for any subwoofer system.• 67,200 mfd capacitance on the battery inputs and 25,000 mfd capacitance on the outputs reinforcing the seat of the pants feeling that you can only get from a MMats Amplifier leading many people to say “MMATS amplifiers are extremely underrated”.
