Power - 2000 watts Max X 1 @2-ohms, 1000 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.
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.
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.
Variable bass Boost - bass Boost allows you to adjust the low bass within the boost Range to just the way you like it.
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.
Dimensions - 13.13 x 6.5 x 2.8, weight - 3.81 lbs. It can be installed in a variety of different places due to its slim and Compact design.
Warranty - BOSS Audio provides a powerful 6-year platinum online dealer warranty so long as the purchase is made through Amazon.Com. We strongly encourage professio....

Power – 500 Watts Max x 2 @2-Ohms, 250 Watts Max x 2 @4-Ohms, 1000 Watts Max x 1 Bridged @4 Ohms.
Full Range – With a Full Range amplifier you not only have the option to run your speakers, but also your subwoofers.
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 and 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.
