Sound Storm Laboratories US8 8 Inch Under Seat Powered Car Audio Subwoofer - 800 Watts Max, Low Profile, Built in Amplifier, For Truck, Boxes and Enclosures, Remote Subwoofer Control 8 Inch Under Seat Subwoofer - 800 Watts Max, Low Profile, 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 PWM - Pulse Width Modulated design simplifies power supplies.

It controls the output voltage and current precisely by removing the output current sensing loss & eliminating all secondary feedback circuitry.

It's efficient & reliable 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(s) High Level Inputs - Speaker level inputs are commonly referred to as high-level inputs.

It will be used to connect the US10 to your factory radio or an aftermarket radio that does not have low-level (RCA) inputs Low-Level Inputs - Line level inputs, also known as RCA inputs or low-level inputs, use RCA interconnect cables to link the US10 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 Phase Control - Phase control lets you adjust the speaker phase with the amplifier if your speakers or subwoofer are hooked up out of phase
