About the Kicker KM604W

Great sound, subtle design

These powerful Kicker 6-1/2" speakers are tough enough for marine duty, but easy on your ears. The durable poly woofers and 1/2" balanced dome tweeters cut through wind, waves, and engine roar to deliver great sound without annoying harshness. The classic white grilles will look great in your boat, too.

Great sound, subtle design

These powerful Kicker 6-1/2" speakers are tough enough for marine duty, but easy on your ears. The durable poly woofers and 1/2" balanced dome tweeters cut through wind, waves, and engine roar to deliver great sound without annoying harshness. The classic white grilles will look great in your boat, too.

Like all KM Series models, Kicker designed these 4-ohm 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 fresh water 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 industry standards for environmental humidity and corrosion. The speakers feature sealed motors, cones, and locking wire terminal covers.

Size: The41KM604Ws fit into standard 6-1/2 and 6-3/4 openings (standard car speaker sizes), but the frame is even bigger than a typical 6-3/4 speaker, so they are not likely to fit easily in any car applications.

Grilles: The grilles are not removable.

Stainless Steel Hardware: The provided hardware is forged from corrosion-proof stainless steel.

Q
can you wash these down? I don't mean blasting it with water just rinsing.
[ DAVID  Jan 18, 2019 ]
3 answers
A
Yes you can and it is a good practice to wash them down.
[ Felix  Jan 21, 2019 ]
A
I put a pair of these in my jet ski haven't had water issues at all
[ Stephen  Jan 20, 2019 ]
A
Ive washed mine after use in saltwater with a garden hose and spray nozzle. When I pressure wash my boat I spray around the speakers. Side note, life expectancy is 2yrs at best. I haven't tried more expensive speakers to see if they have better life, but these are great for those 2 years, then the cones crack.
[ Travis  Jan 18, 2019 ]
