Kenwood Performance Series car amplifiers offer long-term reliability and superior sound quality in a compact, no-nonsense package. The KAC-8105D mono sub amp punches out up to 500 watts RMS to your subwoofers. A rugged cast-aluminum heatsink keeps this amp running at optimal temperatures, even when you're pushing your system hard.

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

An aluminum cover plate covers and protects the amp's controls and connections, giving your installation a professional look. Speaker-level inputs and signal sensing turn-on allow these amps to hook up to factory radios without preamp outputs.
