Power - 1100 Max x 1 @ 2 Ohms, 550 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
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
Switchable Bass Boost - Bass Boost allows you to adjust the low bass within the boost range to just the way you like it
Variable Input 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: 9.13” x 10.44” x 2.25”, Weight: 4.43 lbs., Speaker Impedance: 2 to 8 Ohm, THD @ RMS Output: 0.01%, S/N Ratio: 102 dB, Frequency Response: 9 Hz to 50 kHz, Fuse Quantity: 1 30 Amp ATO Blade
Warranty - BOSS Audio Systems provides a 6 Year Platinum Online Dealer Warranty for purchases through Amazon.Com. We strongly encourage professional installation of this product to ensure proper functionality

AD8317 CHIP---The logarithmic power detector is designed by using AD8317 chip, and is used for RF signal power detection
APPLICATION AREAS---The logarithmic power detector could be used for RF transmitter PA set point control and level monitoring; Power monitoring in a radio line transmitter; RSSI measurements in base stations, WLAN, WiMAX, and radar
55dB---The greater the amplitude or power of the RF signal, the higher the output voltage, and the output voltage is directly proportional to the logarithm of the input signal amplitude, thus expanding the dynamic range of the detected signal, which ranges reach 55dB
-55dBm to 0dBm---The logarithmic power detector can detect power in -55dBm to 0dBm of an RF signal, so that the RF signal is converted to DC voltage output
WIDE APPLICATION---The logarithmic power detector could be widely used radio frequency signal detection, signal power measurement, environmental field strength detection, or as a part of automatic gain control and automatic level control
