FeaturesMonoblock class A/B, MOSFET power supplyHigh and low level inputsVariable low pass crossover, switchable bass boostInclude remote subwoofer controlBlue illuminated planet audio logoClass A/B:Class A/B amplifiers have long been known for their ability to produce great quality sound while performing more efficiently than pure Class A amplifiers. We have developed a specific linear circuitry that further reduces distortion while increasing both sound quality and power output2 Ohm Stable:The lowest impedance accepted by this amplifier is 2 ohms. Amplifiers that are 2 ohms stable produce more power resulting in more volume. This amp can comfortably power speakers or subwoofers with all channel(s) being used at a load of 2 ohmsMosfet:MOSFET stands for Metal Oxide Semiconductor Field-Effect Transistor. MOSFETs are used either as a switch or to amplify a signal. MOSFETs are superior to other FETs, because they require less current to operate, which makes them better suited for car audioSpecificationsWattage: 1500 wattohm Unit: 1Frequency Response: 20 Hz to 20 kHz 1 dBSpeaker Impedance: 2 to 8Dimension: 0'' H x 12'' W x 145'' LWeight: 7.6 lbs
