Compact yet powerful, the Kenwood KAC-531 Class D mono amplifier delivers clean, punchy bass without taking up much space. With peak power of 1000W and RMS ratings of 300W at 4 ohms and 500W at 2 ohms, it handles everything from modest subs to high-demand setups.

Efficient, Cool, and Clean

Class D design ensures high output with minimal heat, reducing strain on your vehicle’s electrical system. Advanced features like the magnetic-shielded output coil and PMLCAP capacitors provide tight, distortion-free sound for bass that hits hard while staying clear.

Precision Bass Control

Equipped with a variable low-pass filter, bass boost, and an infrasonic filter cutting below 25Hz, the KAC-531 delivers deep, defined bass without muddying the mix. An optional wired remote (KCA-RC01A) lets you adjust sub levels from the driver’s seat.

Simple Installation

All connections are on one side, with secure gauge-style terminals and an included Speaker Level Input Harness for easy integration with factory head units.

Compact, Road-Ready Design

Measuring 8-3/8” × 2-1/16” × 5-7/8” and weighing 3.3 lbs, this amp fits tight spaces while providing robust performance for serious bass enthusiasts.

Powerful, efficient, and compact, the Kenwood KAC-531 brings high-quality bass performance to any car audio setup.
