Kenwood Excelon XR1001-1 Mono Amplifier

The Kenwood Excelon XR1001-1 is a mono subwoofer amplifier built for car audio systems. It delivers 500 watts RMS at 4 ohms and 1,000 watts RMS at 2 ohms. A Class-D circuit design operates across a 20-200 Hz frequency response. Upgraded components and a specialised LC filter reduce noise and distortion for high-resolution audio playback.

Ideal for Single Subwoofer Systems

This amplifier suits installations driving one subwoofer at either 4-ohm or 2-ohm loads. Builders who need multi-channel amplification for full-range speakers should look elsewhere. The mono design cannot power front or rear speaker pairs. Systems requiring more than one amplifier channel will not be served by this unit.

Power Output and Filter Headroom

The amp comfortably handles 500 watts RMS into 4 ohms and 1,000 watts RMS into 2 ohms. A variable low-pass filter adjusts from 50-200 Hz at 12 or 24 dB per octave. The subsonic filter covers 15-40 Hz at 24 dB per octave. Bass boost reaches 18 dB at 40 Hz. Headroom ends at the rated RMS limits and the 200 Hz upper frequency boundary.

Questions about this item

What power and ground wire gauge do I need to supply the three 40 A fuses on this XR1001-1?

Four-gauge power and ground leads are recommended to handle the three 40 A fuses fitted to the amplifier.

Will the speaker-level inputs on this mono amp turn the unit on automatically from my factory head unit?

Yes, the speaker-level inputs include signal-sensing turn-on so the amplifier powers up when it detects audio from the factory radio.

How can I verify the low-pass filter is attenuating correctly after I set it between 50 and 200 Hz?

Play test tones through the subwoofer and measure output; the slope should drop at 12 or 24 dB per octave above the chosen crossover frequency.
