Smooth Detail
Kicker designed their KS Series lineup to be a substantial step up from your factory speakers. The KSS504 5-1/4" component system features two quality woofers, two powerful tweeters, and two external crossovers. The polypropylene woofer and its powerful magnet provide a natural sound with a satisfying low end, while the 1" silk dome tweeter prioritizes smoothness in your music's vocal and instrumental details. Kick out your stale, old sound and rediscover how your favorite songs were meant to be heard.
Pro Versatility
Kicker also gives you the option of screwing the component tweeters in place of the woofer's removable phase plug, giving you a coaxial speaker that benefits from the superior performance of an external crossover. Installed as 2-way speakers, you can aim the tweeters to direct high-frequency response in your vehicle.
Great with All Kinds of Power
While we'd recommend using an aftermarket amp to power this system, Kicker gave the KS Series a highly sensitive design that conjures hefty volume even from low-powered factory radios.
Fit Matters
These low-profile speakers feature a reduced mounting depth, making them a match for almost any car. And the refined, black grilles included with the package allow you to do a custom installation that'll add nice flair to your car's interior.
