About the Kicker KM604W
Great sound, subtle design
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.

No connectors for speaker wire connection
Crutchfield customer from Dunn, NC on 7/4/2019
I purchased this product to install on my boat. The only problem is the speakers did not come with the female slip connectors and are a non-standard size. You all sell an assortment pack for $1.99 but shipping is almost $7.00 dollars
Pros: Reputation of manufacture
Cons: Missing parts

Great upgrade to my Sea Ray- Crisp highs and more bass
Crutchfield customer from Gainesville, VA on 5/30/2019
Whole lotta thump and sound compared to the Sony Marines I removed after failing in the first year. They look aggressive, sound great and fit is perfect. They worked so well that I installed 2 more sets of Kicker speakers throughout my Sea Ray and it sounds incredible. I do have a factory amplifier running to all the speakers and wha a difference in overall rich sound with more base compared to previous Sony speakers. Time to crank it up for the summer and enjoy tunes the way it should be. Kicker, you ROCK!!!
Pros: great fit, fuller sound compared to Sony & other brands, sound incredible with amp, look aggressive and sound great
Cons: None at this time

Crutchfield customer from Chapel Hill, NC on 5/15/2019
I purchased these to replace the stock Clarion speakers in a 20 year old Mastercraft. I'm not looking to blast my eardrums, just wanted improved clarity while out on the lake. These speakers delivered exactly what I was looking for.

Loud and clear!
Felix from Dorado, PR on 8/20/2018
Let me give you my recipe for a great and not expensive sound system. One Clarion xc2510 amplifier Four Kicker km604w One Bazooka mbt8014 Any receiver of your choice It sounds loud and clear in my open fisherman 22' panga boat. Much better than I was expecting. Very important is the placement of the speakers in your boat. Refer on Crutchfield articles and videos for more information. They were very helpful for me.
Pros: Looks good. Sounds great. Nice bass. Good price.
Cons: None for now.

Kicker 6.5 marine
Crutchfield customer from Neenah, WI on 8/14/2018
Good sound - Sound is quite directional. Would be nice if you could pivot the tweeters.
Pros: Looks and sounds great. Grill is permanent and won't fall off.
Cons: Sound imaging is fairly directional - best if mounted higher or farther away in the boat.

Cheap screws
Andy from Somersworth, NH on 6/17/2018
Applaud Crutchfield delivery. My first Kicker speaker purchase. The sound is as expected for the cost. Made overseas, while this may not effect performance I am giving away one star to quality assurance. The screws supplied if at all a level of stainless steel are cheap not worthy of mounting them in the stream of salty air on my boat. One cheap screw had no slots in the screw head. Indicative of an assembly worker grabbing a hand full of junk screws from a bin and wrapping them in plastic wrap. I used the screws that were previously used to mount JVC speakers. Irony.
Pros: Prompt delivery, well packaged.
Cons: Junk hardware

Great sound/easy installation
Tom from Northern Virginia on 7/24/2017
I purchased the speakers based upon the reviews I read at Crutchfield. The performance did not disappoint and the replacement installation took less than 10 minutes. I am using the speakers(2) on a 22 foot pontoon boat and they can be clearly heard by all people on the boat. When I take the boat out of the water in the Fall, I will certainly consider adding two additional speakers. The speakers arrived promptly from Crutchfield and the entire experience was very positive.
Pros: Easy install and great sound
Cons: none so far

Great speakers for the price
Jim from Edgewood, MD on 6/19/2017
These speakers sound great compared to the 13 year old factory speakers. Installed 1 set in the cockpit of my Sea Ray 260 and have another awaiting install on the radar arch. Combined with a Sony MEXM71BT head unit and Alpine KTP445U amp. At 2" depth, these are the slimmest marine-grade speakers available in a white color (only thinner speakers are Polks but they are black). This is a big deal especially when installing on a radar arch that very in thickness and even with these speakers, I had to have a friend fabricate a 1/2" PVC spacer.
Pros: 2" depth. Great sound for the $$
Cons: None

T.J. from Geneseo, IL on 1/15/2017
Put these in a Jeep Wrangler. Fit the factory sound bar with minimal modification. Power via and alpine 45 watt amp. They look great and deliver clear, crisp mid-range as component. I experienced distortion at louder volume prior to activating the high pass filter, so probably not going to give you much bass if that's what you are wanting.
Pros: Look awesome, good sound.
Cons: Not good for bass.

Great speakers. Got some guidance and help from the staff dedeciding on the right choice. Installed them two weekends ago. Still a little too cool to be out on the lake but spent most of last weekend sitting in the slip enjoying! Very eclectic music taste and these sounded great across all genres. Looking forward to getting away from the dock so I can crank them up a bit without dirty looks from my Marina neighbors.

notfastnotfurious from Wisco on 7/24/2015
The speakers themselves are awesome. I'm not a big audiophile so i can't tell you how much better the mid's were than the hi's, but they sounds great in the boat, and when paired with the amp i picked up kick out great sounding music all that way up to the head unit's max volume. I would have given a 5 star review, but i'm disappointed that Crutchfield didn't ship plug on leads for the speakers, c'mon Crutchfield?!
Pros: I said above
Cons: no plug on leads for speakers, must make your own or solder some on

Excellent value!
DaveL from Minnesota on 6/12/2015
I ordered two pairs to replace the four original marine speakers (2003) that had completely degraded. I am really happy! These Kickers are a terrific value! The bass is solid and the mid and high ranges sound fine. Running off stock JVC deck at 45 watts per channel. There are a lot of options for stock/OEM replacements... Kicker is a very good choice.
Pros: 1.) Ease of installation 2.) No separate grill; cover "grill" integrated into speaker frame. 3.) They sound very good in factory locations.
Cons: No problems that I encountered.

Great spekers
Dander3 from South Carolina on 5/27/2015
I bought these to replace a pair of Clarion marine speakers that blew after a year. All I can say is WOW, these kickers are great for the price. The bass is impressive and the highs are pretty good. I'm still running them on my old Jensen head unit, but I'm sure they would sound even better with more power. I had several people ask this weekend if I had a sub on the boat the bass was so good. I would absolute recommend these speakers.
Pros: Great bass Very efficient
Cons: the tweeter is a little scratchy, but still good for the price.

Much better than factory
DM from Ohio on 4/20/2015
I replaced my factory 6.5" speakers in my Yamaha 242 Limited. I kept the factory head unit and the new Kickers sound 100 times better. I know they perform even better with an amp but I chose to keep my factory unit for now. Well worth the investment and the advice I received from Crutchfield was 100% on par with what I needed. Thanks!
Pros: Great value, great sound, superb sensitivity, low power need

CarlG from Ridgefield, CT on 9/5/2014
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.

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.

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.
