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
