Kenwood Excelon X500-1 Class D Mono Power Amplifier

This is a Kenwood Excelon X500-1 mono digital amplifier, designed for car audio subwoofer applications. The unit features a black brushed-metal finish on its heavy-duty heat sink chassis, accented by silver-tone lettering and branding. Notable markings include the 'eXcelon' logo in the upper left, the primary 'KENWOOD' logo in the center, and technical specifications in the lower right indicating a '1000W MAXIMUM POWER' and '300W x 1' RMS output. As a Class D amplifier, it is designed for high efficiency and compact size relative to its power output. The physical condition shows significant signs of use, including numerous surface scratches, scuffs, and abrasions across the faceplate and top cooling fins. Dust accumulation is visible in the recessed areas and around the 'Power' indicator triangle. The manufacturer's sticker on the lower right shows peeling at the edges and surface wear. These cosmetic defects suggest a history of rough handling or unmounted storage, though the structural integrity of the metal housing appears intact. This model was a popular mid-range car audio component during the early-to-mid 2010s, valued for its stable power delivery and the reputation of the Excelon line's higher-quality internal components compared to standard Kenwood models.
