Kenwood KAC-531 Class D Mono Power Amplifier

Looking to take your bass game to the next level? The Kenwood KAC-531 might just be the secret weapon your car audio setup’s been missing. This compact Class D mono power amplifier delivers serious punch, smart filtering, and clean, noise-free sound—without taking up a ton of space.

Serious Power in a Small Package

Don't let the size fool you. The Kenwood KAC-531 dishes out a peak power of 1000W, with RMS ratings of 300W at 4 ohms and a solid 500W at 2 ohms. That means whether you’re running a modest sub or something a bit more beastly, this amp keeps the lows tight and impactful. It’s all muscle, no fluff.

Class D Efficiency Without the Heat

As a Class D amplifier, the KAC-531 is designed for efficiency. It runs cooler, delivers more output per watt, and takes less stress on your vehicle’s electrical system. You get strong, clean bass without frying your setup or draining your battery. It’s like hitting the gym and never breaking a sweat.

Crystal Clear Audio with Less Noise

Kenwood loaded this amp with some clever tech to boost clarity. Its Output Coil with Magnetic Shield keeps unwanted magnetic interference out, so your bass doesn’t come with a side of buzz. Add in high-quality PMLCAP capacitors in the LC filter circuit, and you've got tight, distortion-free sound that hits hard but stays clean.

Bass Control Done Right

This amp’s all about giving you control over your sound. There’s a variable low-pass filter, bass boost, and an infrasonic filter that cuts off ultra-low frequencies below 25Hz. Translation? You get deeper, more defined bass that won’t muddy up your system or waste power trying to hit notes you can’t hear.

Easy Tuning with Optional Wired Remote

Don’t feel like digging under your seat every time you want to tweak the bass? The Kenwood KAC-531 is ready for an optional wired remote level control (KCA-RC01A). With it, you can fine-tune your sub volume right from the driver's seat. Smooth.

Built for Clean, Hassle-Free Installs

Every connection is located on one side of the amp, making for a neater setup. The gauge-style terminals come with set screws that lock wires securely in place, so nothing comes loose mid-ride. And if you’re using a factory head unit, you’ll appreciate the included Speaker Level Input Harness, which makes integration a breeze.
