PS Coaxials
PS5250 Coaxial System
Perfect for those who push it a little harder.

KICKER Powersports revs up with its Coaxial Speakers, weather-proof drivers specifically created as fairing drop-ins on motorcycles, or with UTV, ATV, marine, or outdoor systems. PS Coaxial Speakers flaunt high-efficiency, super-lightweight motors for proper bike handling, and extreme power – perfect for those who push it a little harder.





Joining the existing PS5250 is the potent PS4 4-inch Coaxial System and the powerful PS69 6-by-9-inch Coaxial System. They include removable grilles, resist the harshest elements and handle whatever Mother Nature can dish out. The highest-grade materials and adhesives were used throughout the design process to create completely weather-proof speakers.

PS4 Coaxials employ a sophisticated, rare-earth neodymium magnet structure, super light-weight for proper bike handling while offering extreme power for those who like to push it to the brink. The neodymium structure allows maximum output with extremely low weight, superb transient response and high vocal articulation for the utmost tonal clarity. They fit perfectly into the 88-05 Honda Gold Wing Fairing and rear-seat or other cutouts that have the 4” or 5” factory locations. The PS4 system also fills KICKER 4-inch Empty Bullet Enclosures (KMMTES/sold separately), which fasten to motorcycle handlebars, Bimini tops or golf-cart roof supports.

As the largest driver set in the Powersports lineup, the rugged PS69 system utilizes heavy-duty ceramic magnets for high power handling and volume, ultra-clear and loud for music reproduction through helmets at highway speeds. Thoroughly weather-proof, they’re great for the burgeoning motorcycle bag-lid market, side-by-side UTVs, or off-road Jeeps and other 4x4 vehicles.

The sizes join a coaxial lineup that already includes a 5-1/4-inch set (PS5250) that fits Harley-Davidson® and Victory® motorcycles. PS-Series Speakers are available in both 2-Ohm and 4-Ohm impedances, so they are compatible with upgraded amps and stock head units.

The entire PS-Series boasts super-efficient, 20mm neo-titanium-dome tweeters bridge-mounted over the woofers to counter extreme vibration, and incorporates a tweeter sensitivity jumper. Designed as high-efficiency speakers for low current draw from small Powersports charging systems, the PS-Series provides quality without draining a vehicle’s battery life or sacrificing high volume levels that should be heard over the roar of the road.

I purchased these speakers at Daytona Bike Week, and was told that they would be the perfect replacement for the stock speakers in my FLHX. This couldn't more true. There is no noticable distortion when turning the volume to 80 or 90 %. They sound great at 75 MPH, unlike the stock units. I highly recomend this product for an inexpensive upgrade to a stock stereo on a Harley Touring bike.
