$130.00

KS Series 6″x8″ 2-way car speakers

Kicker designed their KS Series speakers to be a substantial upgrade from factory speakers or older, deteriorating aftermarket speakers. The 51KSC6804 6″×8″ speakers feature polypropylene woofers that provide a satisfying, natural sound, paired with 3/4″ silk dome tweeters that deliver smooth reproduction of your music’s vocal and instrumental details. These speakers offer impressive performance even when powered by a factory radio, thanks to Kicker’s highly sensitive design that produces substantial volume from low-powered factory systems. If you’re not planning to swap out your factory radio or add an amplifier, these speakers will still deliver a noticeable improvement over your original speakers. The 51KSC6804 speakers feature a low-profile design with reduced mounting depth and minimal tweeter protrusion, making them compatible with most factory locations. While these speakers are described as 6″×8″, they also fit many 5″×7″ applications, making them versatile for various Ford, Mazda, and other vehicle applications.
