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.

  • 2-way 6-1/2" marine speakers (pair)

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.

what i expected

Written By markos, san diego on Saturday, September 27, 2014

Crutchfield Customer Review (What's this?)

put them in my 32 foot monterey. they sound as expected. my issues stem more from needing more power and a sub than anything. but these speakers fit their need. i'm satisfied with them.

Surprise Performance

Written By CarlG, Ridgefield, CT on Friday, September 05, 2014

Crutchfield Customer Review (What's this?)

I didn't expect the response range and the efficiency from these speakers. Sound quality equal to speakers costing much more. Performed very well at higher volumes while operating the boat.

Pros: Great quality at an affordable price

Cons: Wished they were a little smaller to fit in original cut outs.

What an improvement!

Crutchfield Customer Review (What's this?)

Huge improvement over the stock speakers in my boat. Better sound throughout the entire listening range. I'm sure these speakers would really deliver with a marine amplifier!

Pros: Great performance. Excellent price.

Written By Jeff, Tim's Ford Lake, TN on Tuesday, July 08, 2014

Crutchfield Customer Review (What's this?)

I put 4 of these speakers in my boat and they sound great. They have excellent depth/bass. The 22 watt Kenwood gives them plenty of power for all the volume and quality sound I need. I am very pleasantly suprised with these speakers.

Pros: depth/bass and quality sound at high volume

Cons: Measurement provided but no "cut out" template to trace for marking hole cut. Expected one on the box but not there.
