BASS8 Under Seat 8 Inch Car Subwoofer, 800 Watts

Space Saver - A great solution for tight spaces. This unit integrates an amplifier and subwoofer into one, making it perfect for vehicles with limited room. Its slim profile provides several installation possibilities. Pulse Width Modulation (PWM) - PWM simplifies power supplies. It precisely regulates output voltage and current by removing output current sensing loss and secondary feedback circuitry, improving efficiency and dependability. Variable Low-Pass Filter - An electronic circuit that removes all notes below the set frequency. Use this filter mainly to keep high notes out of your subwoofer(s). High-Level Inputs - Often called speaker-level inputs. These are used to connect the unit to a factory radio or an aftermarket radio lacking low-level (RCA) outputs. Low-Level Inputs - Also known as RCA inputs, these utilize RCA cables to connect the unit to the source. Many aftermarket radios have multiple pairs of RCA outputs for connecting to several amplifiers. Variable Bass Boost - Enables you to adjust the low bass within the boost range to your liking. Phase Control - Allows you to adjust the speaker phase with the amplifier if your speakers or subwoofer are connected "out of phase"
