Better Sound than Stock

Many boats come with factory- (or dealer-) installed audio systems. The speakers they use are usually of inferior quality that just doesn’t do justice to your tunes. By upgrading to the Kicker 45KM42 marine speakers, you’re going to get something that sounds as good as can be. Soaring highs and solid mid-bass performance are going to trick you into thinking that you’re entertaining the musicians on the boat itself.

Built to Withstand the Elements

The most important thing in the craftsmanship of a marine speaker is that it can withstand the water, salt, fog, etc. that is found out on the water. The Kicker 45KM42 4” 2-way coaxial speakers are meant to thrive in this atmosphere. The UV-treated polypropylene woofers with Santoprene™ surrounds are durable and water-resistant. The titanium dome tweeters also handle the environment with ease. The included mounting hardware is stainless steel designed to combat rust and corrosion.

Two Grille Colors to Choose From

Included with each 45KM42 speaker kit are two pairs of sporty grilles: one pair is charcoal-colored and the other is white. They are designed to either blend in with the rest of the boat or offer a contrast to have the speakers stand out. Regardless of the color that you choose to display, rest assured that not only are the speakers looking their best, they are also protected from damage.
