Infinity Kappa One K

This handsome little black box delivers massive bass and fits almost anywhere in your car. Infinity's Kappa One K mono subwoofer amplifier can supply your sub with up to 1,000 watts RMS — good news for everyone who likes really strong bass. A low-pass filter clears the way for your sub to play clean, powerful bass tones. The amp also features Infinity's Dynamic Bass Optimizer (DBO™) circuitry, which uses a subsonic filter and bass boost to optimize the performance of your sub and enclosure combo. The Kappa One K can accept low- or speaker-level inputs so it'll work in almost any system — and Infinity includes RCA-to-speaker wire adapters so you'll make the right connections. They also include an electrical anti-rotational locking (E.A.R.L.) ground terminal, which provides a more conductive and secure ground connection for the amplifier. A wired remote lets you control your bass level from the front seat. Kappa One K input and control panel
