About the Kicker 49KM604W

Get rockin' on the water
Get rockin' on the water
Kicker brings their awesome sound to the water with these tough 6-1/2" speakers. Their durable polypropylene woofers and 1/2" balanced dome tweeters cut through the sound of wind, waves, and engine roar to supply the Kicker sound quality you expect. The white grilles add cool flair to any deck.
Weather-tough
Kicker designed these speakers for life on the water, with sealed motors, rubber cone surrounds, and locking terminal covers to keep spray away from the internal componentry. They'll also stand up to harsh sunlight, thanks to special UV treatments on the cones, surrounds, baskets, and grilles. Whether you're on freshwater or salt, these speakers will give you years of outstanding performance.

Product Research
Features
Marine-Ready: The Kicker KM series marine coaxial speakers are engineered to meet or exceed ASTM B117 Salt Fog (200 hour test) and ASTM G154 Accelerated UV (400 hour test) industry standards. The speakers also feature sealed motors.
Size: Although the KM604s will drop into many standard car speaker openings, the grilles are fixed and the frames are oversized, so they won't fit in most car applications and we don't sort them with car speakers.

So far so good. Paired 4 of them with a 1000w pyle amp and the sound is very good on my pontoon boat. Thanks for the help and advice Crutchfield. Always a pleasure doing business with you.
