eXcelon Motorsports 4-Channel Class D Amplifier

The Kenwood eXcelon Motorsports XM302-4 is a rugged, compact 4-channel Class D amplifier engineered to deliver high-resolution audio performance in demanding environments such as marine and motorsports applications. It is capable of reproducing ultra-high frequencies up to 50kHz, providing a richer and more detailed sonic experience that standard amplifiers may miss. Its compact Class D design ensures high power output with excellent efficiency and minimal heat generation, making it suitable for installations where space is limited. The one-sided connection layout simplifies installation and wire management, while the included sliding terminal cover offers a professional and streamlined appearance. Functionality is enhanced with a signal-sensing turn-on feature that automatically powers the amplifier when an audio signal is detected, eliminating the need for a separate remote turn-on wire. Variable high and low-pass filters (50Hz - 200Hz) allow for precise tuning of speakers and subwoofers, and Channel B includes a Bass Boost control (0dB to +18dB at 40Hz) for added low-end punch. A speaker-level input harness is included for seamless integration with factory head units that lack RCA outputs. The amplifier is CTA-2006 compliant, guaranteeing honest and reliable power specifications. With RMS power outputs of 50W x 4 at 4 ohms, 75W x 4 at 2 ohms, and 150W x 2 bridged at 4 ohms, the XM302-4 offers versatile power delivery. Its frequency response ranges from 20Hz to 50kHz (+0dB, -3dB), and it has a signal-to-noise ratio of 100 dB. The unit operates on 14.4V (11V - 16V allowable) and measures 8-3/8" W x 2-1/16" H x 5-7/8" D, weighing 3.1 lbs.
