Kenwood built the KAC-8103D amplifier from the ground up to power your subs with authority. Its rugged cast-aluminum chassis houses an efficient mono power amp that'll punch out up to 500 watts RMS without putting a strain on your car's electrical system.

A built-in low-pass filter adjusts amplifier output so you'll get the best sound possible from your subwoofer/box combo, while the subsonic filter eliminates inaudible, ultra-low bass that can detract from your sub's performance. You can dial in up to 18 dB of bass boost if you want to fatten up the sound.

The top-mounted controls allow you to tweak the sound easily, and convenient front-side connections make setup a snap. Speaker- and preamp-level inputs, plus preamp outputs, provide flexibility in system design and hookup.
