Designed to fit seamlessly into almost any vehicle, these speakers are a significant leap from stock models, delivering exceptional sound quality. Whether you're a casual listener or an audio enthusiast, these speakers ensure that your music sounds the way it’s meant to be heard, with smooth highs, clear mids, and strong bass.

Potent Performance for Any Ride

These speakers are engineered to handle everything from soft acoustic songs to high-energy rock anthems. With Kicker 51KSC6804 speakers, you can crank up the volume to concert levels without sacrificing the clarity and subtlety of your music. Whether you love clean, crisp vocals or punchy bass lines, these coaxial speakers handle it all. Thanks to their polypropylene woofers and durable rubber surrounds, you get well-balanced midrange and midbass that stand up to the demands of a variety of genres.

Extended Frequency Response

One of the standout features of the Kicker 51KSC6804 is its extended frequency range of 45-21,000 Hz. This broad spectrum ensures that the speakers can handle everything from low, thumping bass to soaring, high-pitched vocals. Combined with the silk dome tweeters, these speakers deliver detailed sound, allowing you to hear every element of your music with pinpoint accuracy.

Smooth Silk-Dome Tweeters for Detailed Highs

A smooth sound is key when enjoying music, and the silk-dome tweeters on the Kicker 51KSC6804 do not disappoint. These tweeters produce natural, detailed highs without any harshness or distortion, giving your music a clean and crisp sound. Whether you're playing smooth jazz or heavy metal, the tweeters offer a rich experience that brings out the finer details of your tracks.

Polypropylene Woofers and Durable Rubber Surrounds

The polypropylene woofer combined with the rubber surround plays a crucial role in producing clean, precise midrange and midbass tones. These materials are designed to be both lightweight and rigid, allowing for optimal sound performance and long-lasting durability. The result is a woofer that handles a wide range of frequencies while maintaining high efficiency and a deep, resonant sound.

Perfect Fit in Almost Any Vehicle

One of the most convenient aspects of the Kicker 51KSC6804 is its thin-mount design, which makes installation simple. With a mounting depth of just 2.282 inches and zero tweeter protrusion, these speakers fit easily behind factory grilles in nearly any vehicle. Whether you're driving a compact sedan or a larger SUV, you can count on these speakers to fit snugly without the need for any complex modifications.

High Power Handling for Versatile Use

The Kicker 51KSC6804 speakers boast an impressive power handling range of 15 to 75 watts RMS and 150 watts peak power. This makes them suitable for both factory and aftermarket systems. You can power them with a factory radio or an external amplifier, and they’ll still deliver great sound. Whether you’re keeping your factory system or upgrading to an aftermarket setup, these speakers will rise to the occasion.

No Grilles Needed – Fits Behind Factory Grilles

For those who prefer a clean and stock look inside their vehicle, these speakers come without additional grilles. They are designed to fit behind factory grilles or panels, maintaining the original appearance of your car’s interior. This ensures that you get upgraded sound without altering the aesthetic of your vehicle.

If your current speakers are starting to fade, you might be missing out on some of the finer details in your music. The Kicker 51KSC6804 was designed to breathe new life into your tunes, making each song sound as vibrant as the day it was recorded. With smooth, well-rounded highs and tight midbass, you’ll hear your favorite songs in a whole new light, whether you're streaming from your phone or listening to the radio.

Highly Sensitive Design for Factory Radios

Worried that your factory radio won’t provide enough power? The Kicker KS Series has you covered.
