US10K 10 Inch Powered Under Seat Car Subwoofer - 1000 Watts Max, Dual 4 Ohm Voice Coil, 8 Gauge Amp Installation Kit

Built-in Amplifier - A Pulse Width Modulated design simplifies the power supply. It precisely controls the output voltage and current by eliminating the output current sensing loss and removing all secondary feedback circuitry. This design is efficient and dependable. KIT Contains a 17/8G red power cable, a 40 amp fuse holder, a 3/8G ground cable, a 16/18G blue remote cable, a 16 RCA interconnect, 4" wire ties, plastic grommets, #10 gold-plated ring terminals, butt splice wire connectors, a tap screw, and a rubber terminal boot. Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all notes below the filter's frequency setting. Use the Low-pass filter mainly to keep high notes out of your subwoofer(s). High Level Inputs - Speaker level inputs are often called high-level inputs. They are utilized to connect the amplifier to a factory radio or an aftermarket radio lacking low-level (RCA) inputs. Low-Level Inputs - Line level inputs, also referred to as RCA inputs or low-level inputs, employ RCA interconnect cables to link the amplifier with the source unit. Most aftermarket radios have several pairs of RCA outputs that can connect to multiple amplifiers. Variable Bass Boost - Variable Bass Boost enables you to adjust the low bass within the boost range to your liking. Phase Control - Phase control allows you to adjust the speaker phase with the amplifier if your speakers or subwoofer are connected out of phase. The kit includes butt splice wire connectors, a tap screw, and a rubber terminal boot for installation
