TOPSTRONGGEAR 1 Ohm 800 Watts Class D Full Range Mono Block Amplifier, 1/2/4 Ohm Stable, Remote Subwoofer Control

Class D MOSFET Mono Block Power Amplifier.
RMS Power at 1 Ohm:1500 Watts，RMS Power at 2 Ohms: 800 Watts，RMS Power at 4 Ohms: 510 Watts.
Low Pass Crossover - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s).
Remote Subwoofer Level Control Included.Variable Bass Boost - Variable Bass Boost 0 to 12dB(50Hz) allows you to adjust the low bass within the boost range to just the way you like it..
Warranty -TopstrongGear provides a powerful 1 year Platinum Online Dealer Warranty.

Built-in Amplifier - With a MOSFET power supply you get improved switching speeds, better performance with less power from the driver, lower gate-to-drain feedback capacitance, lower thermal impedance for higher switching frequencies.
Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes above the filter's frequency setting. You will use the Low-pass filter to primarily keep high notes out of your subwoofer(s).
High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs. It will be used to connect the LOPRO10 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs.
Low-Level Inputs - Line level inputs (RCA inputs / low-level inputs) use RCA interconnect cables to link the LOPRO10 with the source unit. Most aftermarket radios have multiple pairs of RCA outputs that can connect to multiple amplifiers.
Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
Specs – 15.5” x 11” x 3”. If you are short on space, this is a great solution for you. The combination of amplifier and subwoofer all into one, makes this ideal for spatially challenged vehicles. Weight: 13 lbs..

Power supply EMI filter is a kind of reactance-type low-pass filter, installed at the power supply input of electronic equipment..
It can inhibit noise transmitted through grid power cable, and can inhibit high-frequency interference signals generated by the electronic device itself..
High quality imported components provide obvious filtering effect..
EMI has become a must have device installed in electronic equipment..

Space Saver - The combination of a built-in 300W amplifier that powers the 8” subwoofer makes this ideal for spatially challenged vehicles..
Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the low-pass filter to primarily keep high notes out of your subwoofer. Adjust it from 50-150 Hz to best fit your system..
Ease of installation - Takes either speaker wire (High-level) or RCA cable (low-level) inputs. This makes connecting the QBUS8P to your radio easier since it's compatible with both factory AND aftermarket units!.
Automatic Turn-On - This circuit automatically turns the QBUS8P on whenever it senses an audio signal. This eliminates the need to run a remote turn on wire making installation a breeze..
Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it..
