BOSS Audio Systems PF1800 4 Channel Car Amplifier, 1800 Watts, 2-4 Ohm

Power - 450 Watts Max x 4 @2-Ohms, 225 Watts Max x 4 @4-Ohms, 900 Watts 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 basically an electrical switch that allows the flow of electrical current. It controls the output voltage & current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry

Variable Gain Control - The gain control is not for adjusting volume. It simply adjusts the amount of signal that is coming from your receiver and going to your amplifier
