Elevating Your Drive with Precision Performance

Kicker is known for producing car audio equipment with a focus on performance and durability. These speakers are designed to provide clear and balanced sound reproduction in a car audio system. It's important to check for any updates or changes to the product specifications, as newer models may have been released since my last update in January 2022.

Unleash the Spectrum

The 2-way Coaxial system seamlessly integrates various speaker components, commonly incorporating a dynamic woofer responsible for handling low-frequency sounds and a specialized tweeter dedicated to reproducing high-frequency tones. In this configuration, both the woofer and tweeter operate cohesively within a single unit to deliver a comprehensive audio experience, effectively catering to the entire spectrum of frequencies.

Powerful Sound, Easy Fit

These speakers deliver high-volume performance with smooth, natural sound. Polypropylene woofers with rubber surrounds and silk-dome tweeters provide tight midbass and clear highs, while the thin-mount design—under 3" depth with minimal tweeter protrusion—fits behind most factory grilles.

  • Sounds great! The original speakers did not sound very good so I upgraded to these Kicker speakers for the front doors of my Highlander. Easy step by step directions made for a quick install. I have already upgraded the front dash speakers with Kicker brand and I think I may have to upgrade the back door speakers now!
