More about the product
The Kicker 51KSS365 6.5-Inch 3-Way Component Speakers deliver premium sound quality with a design that fits a wide range of vehicles. This system is engineered for concert-level realism and volume, making it a major upgrade over factory speakers. It includes 6.5-inch woofers with Extended Voice Coil (EVC) technology and powerful magnets for smooth midrange performance. The polypropylene woofer cones are paired with tough rubber surrounds to maintain accuracy and reduce distortion at higher volumes.
The 3-way design combines dedicated midrange drivers and silk dome tweeters for crisp, natural highs and detailed sound across all frequencies. Three mounting brackets are included for the 2-3/4-inch midrange, offering flexibility during installation. Angled, surface, and flush tweeter mounting options allow for custom placement to optimise sound staging. The ultra-thin speaker design uses factory holes and mounting points, making installation simple and clean.
An optimised in-line 12dB crossover network is included to ensure precise frequency distribution between components. With less than a 2-inch mounting depth, the KSS365 fits most vehicles without modification. Grilles are included for a professional finish.
The system has a recommended power rating of 15 to 80 watts RMS, making it suitable for factory or aftermarket head units. The sensitivity rating of 91 dB ensures efficient performance without requiring excessive amplification. Its 4-ohm impedance provides compatibility with most car audio systems.
While the Kicker 51KSS365 offers exceptional clarity and imaging, it is not designed for heavy bass. Pairing with a subwoofer is recommended for those seeking full-range sound. Overall, this component system combines premium materials, flexible installation options, and advanced design for a noticeable improvement in everyday listening.
