Kicker KS KSC680 6x8-inch coaxial car speakers, part 51KSC6804, sold as one boxed pair of two speakers per purchase. The box identifies 4-ohm impedance, 150W peak, 75W RMS, 0.75-inch silk-dome tweeters and a 45 Hz to 21 kHz frequency response. Package-listed contents are two coaxial speakers plus mounting and wiring hardware; the contents have not been individually verified. The packaging mentions Ford and Mazda fit, but specific vehicle fitment is not confirmed, so compare your opening and mounting requirements before a car-audio replacement. Representative photos show one boxed pair with scuffs, creases and edge wear, not every available set. The speakers themselves are not exposed in the photographs and completeness and operation are unverified. Each purchase is one pair, not a bundle of four pairs; box wear and serial identifiers may differ between sets.

Printed KS-series specifications: nominal woofer size 6x8 in / 160x200 mm; tweeter 0.75 in / 20 mm; recommended amplifier power 15-75 W RMS; fast-acting tweeter protection and silk-dome tweeters. The box lists a 127 mm minor-axis and 182 mm major-axis cutout, 58 mm mounting depth, 9 mm gasket thickness and 80 mm magnet diameter. The printed mounting drawing also labels 183 mm mounting length and 107 mm inner span; these are packaging specifications, not measured vehicle fit. The identification panel shows MPN 51KSC6804, UPC 713034058434, 4 Ohm and RoHS compliance. It also says Made in Thailand, while the supplied record and operational SKU use US; the origin field is left unresolved rather than claiming US manufacture. The pictured serial is representative only and is not assigned to every set. No factory-sealed, individually verified accessory-completeness or successful-operation claim is made.
