Kenwood Excelon XR401-4 Class D 4 Channel Power Amplifier
Kenwood’s Excelon Reference Series XR401-4 4-channel amplifier will add clarity and punch 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. 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.

Class D Amplifier Design: The amplifier design is Class D, which uses digital switching power supplies. The result is much higher efficiency (less heat generated) than Class AB.
High-Resolution Audio Compatible: The XR401-4 is compatible with Hi-Res Audio sources which are capable of reproducing frequencies up to 40kHz. Special capacitors and inductors in the amp’s LC filter help to reduce noise and distortion to enhance the sound quality. High resolution audio, with sampling frequencies up to 192khz/24-bit, exceeds CD standards (44.1kHz/16-bit), allowing you to hear much more detail and richness in the music.
