BOSS Audio Systems Elite BE2500.1 Monoblock Car Amplifier - 2500 Watts, 2 4 Ohm Stable, Class AB, Mosfet Power Supply, Great For Subwoofers
POWER: 2500 Watts Max x 1 @2-Ohms, 1250 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 and 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.
SWITCHABLE 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.
