Delivers power in style
This handsome little black box delivers big power and fits almost anywhere in your car. Infinity's Kappa Four 4-channel amplifier can supply four high-performance speakers with 100 watts RMS each — good news for everyone who likes it loud. You could also use this amp to power a pair of front speakers with 100 watts each, and a subwoofer with 240 watts RMS. Variable high- and low-pass filters optimize the amp's output for your speakers and subs, increasing the efficiency of the system.
Good connections
You can use this amp's preamp outputs to connect to a subwoofer amp, like the matching Infinity Kappa One 6 or Kappa One K, so your system will have plenty of low-end punch — a remote output connection on this amp will even turn on your sub amp. The Kappa Four 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.
