BOSS Audio Systems BASS8K 8 inch Powered Under-Seat Car Subwoofer + 8 Gauge Amp Wiring Kit – 800 Watts Max, Single 4 Ohm Voice Coil, Built-In Amp, Remote Control (Sold Individually)

KIT – Includes: 17’ red power cable with ring terminal & rubber boot pre-installed, 3’ black ground cable, 16’ blue remote cable, 40A fuse, 16’ RCA, 1 large black rubber terminal boot, 1 ring terminal, 7 wire ties, plastic groumet, 1 tap screw. Space Saver – The all-in-one design places the amplifier and 8 inch subwoofer together in a slim under-seat enclosure, making it an excellent option for vehicles with limited installation space. The compact profile offers several possible mounting orientations to fit tight cabins. Pulse Width Modulated – PWM design streamlines the power supply by precisely controlling output voltage and current. It does this by removing the output current sensing loss and eliminating all secondary feedback circuitry, resulting in improved efficiency and increased reliability. Variable Low-Pass Filter – A variable low-pass filter is provided; 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 (high-level) inputs are included for installations without low-level RCA outputs. These inputs allow connection of the BASS10K to a factory radio or to an aftermarket head unit that does not provide RCA (low-level) outputs.
