Kenwood eXcelon XR601-1 Class D Mono Subwoofer Amplifier – 600W RMS Total

The Kenwood eXcelon XR601-1 is a compact Class D mono amplifier built for buyers who want real subwoofer power without giving up installation flexibility. Its low-profile chassis makes it easier to fit in tighter vehicle spaces while still delivering serious bass output for aftermarket subwoofer systems.

This amplifier is rated at 400 watts RMS x 1 at 4 ohms and 600 watts RMS x 1 at 2 ohms, with a variable low-pass filter, infrasonic filter, bass boost, speaker-level inputs, and signal-sensing turn-on. That makes it a strong fit for factory integration builds, clean stealth installs, and everyday systems that need dependable mono sub power from a compact chassis.
