Slim enough to fit under seat or any other hideaway location, this 8" Slim Active Bass Enclosure offers a quick and easy way to add a high-powered subwoofer solution to your audio system. The integrated amplifier in the subwoofer features subsonic and low-pass crossovers and a control for adjusting the input sensitivity from 0.2V to 6V. Both high-level (speaker level) and low-level (RCA type) inputs are present, making this a universal solution for use with any head unit or other input source. A variable bass boost control has been included for further flexibility, allowing you to control the subwoofer from the front seat.

Please note that the amplifier wiring kit is not included but is available separately.
