Product: BOSS Audio Systems PM1500 Monoblock Car Amplifier - 1500 Watts, 2/4 Ohm Stable, Class A/B, Mosfet Power Supply, Great for Subwoofers
Brand: BOSS Audio Systems
Power - 1500 Watts Max x 1 @2-Ohms, 700 Watts Max x 1 @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
Mosfet Power Supply - A MOSFET is 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 Low-Pass Crossover - Subwoofers reproduce sound based on a number of different low-range frequencies. You can set exact sound specifications for the bass frequency reproduction
Low & High Level Inputs - A low level (RCA) input is measured in voltages. A high level (+/- wire) input is measured in wattages. Both essentially carry signal from your receiver to your amplifier to your speakers
