Planet Audio AC1800.5 1800 Watt 5 Channel Car Amplifier, Full Range

Power - 300 max x 4 2-Ohms plus 5th channel 600 watts max x 1 2-Ohms, 150 max x 4 4-Ohms plus 5th channel 300 max x 1 -4-Ohms, 600 max x 2 bridged 4 Ohms Class A/B Topology - Class A amplifiers have enormous amount of current flowing through its output transistors with no audio signal. Class B amplifiers have no current flowing through its outputs with no audio signal Full Range - With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers Mosfet Power Supply - A MOSFET is an electrical switch that allows the flow of electrical current. It controls the output voltage and current precisely by removing the output current sensing loss andamp; eliminating all secondary feedback circuitryTrack, Volume and Station Controls
