Product Description

Features & Specifications




Kenwood eXcelon XR401-4 4-Channel Car Amplifier

The Kenwood eXcelon XR401-4 4-channel amplifier will add clarity and bang to your sound, as it powers each of your front and rear speakers with 75 watts RMS. If you’re adding bass first, you can use the amp in 2-channel mode to drive a couple of subwoofers with up to 200 watts RMS each. Then later you can switch the amp over to your main speakers when you get a sub amp. The XR401-4 can fit in many different places in your car because of its incredibly low profile — it’s under 1-1/2″ tall.

Rich and Immersive High-Resolution Audio

High-Resolution Audio is high-quality sound that exceeds CD standard. High-resolution audio captures and beautifully expresses all the details of your favorite music. Through ultra-high and low frequencies, immerse yourself in a rich and high-quality sonic experience.

Smooth waveforms – Loss of smoothless – Fine waveforms

High Performance Parts

Special capacitors and inductors have been carefully selected for the digital amplifier’s LC filter, which is essential for achieving highresolution audio. These high-performance parts reduce noise and distortion and ensure excellent sound quality.

High-resolution music

This XR401-4 Excelon Reference Series amplifier has ultra-high-frequency response up to 40,000 Hz, reproducing sounds that help define audio tone and space even though beyond the range of hearing. Fix this amp up with a nice set of Kenwood high-res Reference Series speakers, and you can enjoy the extended detail and powerful musical imaging of your high-res FLAC or DSD files.

Designed for optimum efficiency

Kenwood packed this amp with space-saving features. Class D technology reduces the size of the power supply, while the internal heatsink is tilted to reduce height without compromising the amp’s cooling system. Recessed power and speaker wire terminals help to further reduce the amp’s footprint, protect the connections, and give your installation a neat, professional look.

Controls for the best sound — especially for active systems

You can contour the sound with high- and low-pass filters so your speakers play efficiently and sound their best. The front and rear channels feature separate gain and filter controls so you can adjust for different types of speakers. The front and rear crossovers also include high-frequency settings that are perfect for tuning tweeters and woofers to sound great in 2-way active systems.

Deep Bass Sound

By using a down-firing subwoofer and superior technologies, the audio system generates high-quality sound and powerful bass, while still being compact.

Enhanced Signal to Noise Ratio

The feedback value of the current XR Amplifier has been optimized to improve the S/N ratio. As a result, the noise level has been reduced by up to 40%.


Specialized Circuit Design

The noise reduction system employs a special layout that separates the analog circuit, digital amplifier circuit and power supply circuit. This keeps interference between the circuits to a minimum, decreasing noise and thereby achieving high performance and sound quality.


Wired Remote Control Included with XR401-4

The wired remote control allows you to adjust the volume of a subwoofer when connected to the head unit.
