The Kenwood eXcelon XR401-4 is a compact 4-channel Class D amplifier built for buyers who want real full-range power without giving up installation flexibility. Its low-profile chassis makes it easier to fit in tighter vehicle spaces while still delivering clean output for front and rear speakers, or a bridged setup when the system calls for it. This amplifier is rated at 75 watts RMS x 4 at 4 ohms, 100 watts RMS x 4 at 2 ohms, and 200 watts RMS x 2 bridged at 4 ohms. Kenwood also equips it with variable high-pass and low-pass filters, speaker-level inputs, signal-sensing turn-on, and an included wired bass knob, making it a strong fit for factory-integration builds and clean aftermarket upgrades.
