BOSS Audio Systems OX1.5KM Onyx Series Car Audio Subwoofer Amplifier – 1500 High Output, Class A/B, 2/4 Ohm, Low/High Level Inputs, Low Pass Crossover, MOSFET Power, Monoblock, Full Range

POWER - 1500 Watts Max x 1 @2-Ohms, 750 Watts Max x 1 @4-Ohms. 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. 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. 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. SWITCHABLE BASS BOOST: Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.. 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 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. SPECS: Dimensions - 10.4” x 7” x 2.3”, Weight - 5.2 lbs.
