Why Choose Kicker 51KSS6804 Component System?
Unleashing Concert-Level Volume with Sublime Precision
KICKER KS-Series Speakers offer concert-level volume with smoothness and subtlety for the most discerning ears. The internally dampened polypropylene cones and robust rubber surrounds help the woofers produce precise midrange and bass, while the high-quality silk-dome tweeters deliver natural, detailed highs.
Elevate Your Music Experience from Every Angle
Explore your music with a component or high-end coaxial system, featuring tweeters with a removable bullet-style phase plug replaced by a unique adapter. This allows the 25mm silk-dome tweeters to rotate and tilt, offering enhanced system design options and superior off-axis performance. Ideal for power ranging from 15 to 125 watts. See below for additional details.
Powerful, Flexible Sound
Enjoy high-volume, smooth, and detailed audio with polypropylene woofers and silk-dome tweeters for tight midrange and clear highs. The thin-mount design fits behind most factory grilles, and the system can be used as coaxial or component, with rotatable and tiltable tweeters for superior off-axis performance.
Frequently Asked Questions (FAQ)
- • Will this component speaker system fit my factory speaker locations?
It is designed to fit many vehicles, but fitment varies by make and model. Check your vehicle's speaker size and mounting depth before installation.
- • Why are the tweeters not producing any sound?
Loose wiring or incorrect crossover connections are the most common causes. Verify all connections before replacing any components.
- • Do I need to install the included crossovers?
Yes. The crossovers send the correct frequencies to the woofers and tweeters for balanced sound.
- • Can I power these speakers directly from my factory radio?
Yes, but an aftermarket amplifier will provide better volume, clarity, and dynamic range. They perform best with clean RMS power.
- • Why do the speakers distort at higher volume?
Distortion is usually caused by amplifier clipping or excessive bass boost. Proper gain adjustment helps prevent speaker damage.
- • Which tweeter mounting option should I use?
You can choose flush, angled, or surface mounting depending on your vehicle and preferred sound direction. Use the included hardware for a secure installation.
- • Why do the left and right speakers sound different?
This is often caused by reversed speaker polarity or incorrect crossover wiring. Double-check the wiring on both channels.
- • Can I replace my factory tweeters without modifying the doors?
Many vehicles allow direct replacement, while others may require minor modifications. Test-fit the mounting hardware before final installation.
- • Why do the tweeters sound too bright?
Tweeter placement greatly affects high-frequency response. Repositioning or aiming them differently can produce a smoother sound.
- • Do the speakers require a break-in period?
Yes. Playing music at moderate volume for several hours helps the suspension loosen naturally and improves overall performance.
