About the Kicker 45KM42

Small speakers produce superb sound

Kicker's 45KM42 4" marine speakers sound terrific and look great on any boat. Designed for life on the water, these speakers feature sealed motors, rubber cone surrounds, and locking terminal covers to keep spray away from the internal componentry. And their 2-ohm impedance will draw a little extra power out of your marine amplifier.

Rugged and versatile

These 4" speakers are tough enough for marine duty, but they're very easy on your ears. The durable poly woofers and 1/2" balanced dome PEI tweeters cut through wind, waves, and engine roar to deliver great sound without annoying harshness. Whether you're mounting them in a bulkhead, or installing them in a set of Kicker's custom enclosures, these speakers will make your day on the water just a little bit better than it was already.

Two sets of grilles

The package includes white and charcoal grilles so you can make these speakers blend in with just about any color scheme. Whichever color you choose, special UV treatments on the cones, surrounds, baskets, and grilles ensure that they'll stand up to harsh sunlight. Whether you're on fresh water or salt, these speakers will give you years of outstanding performance.

Great speakers

James from Culpeper, VA on 7/18/2019

Verified customer (What's this?)

Speakers sound great. Put 4 of them in my fishing boat. Could not find a 3-3/4" hole saw for install but I did find a 3-5/8" hole saw and ran it through the hole at a little bit of an angle in each direction to bore it out a little more. Speakers fit perfect after that.

Pros: Sound great

Cons: None so far

Great looking, sounding little speaker!

Bought these speakers to add a speaker to the transom on my boat. The size was perfect and sound was impressive. The build quality seems to be great and the included wire connector was a nice touch. IMO the speaker grill is the best looking out there right now. Definitely recommend!

Pros: Great styling, compact sound

Cons: Stainless steel screws kinda throw off the look, wish there was screw plugs.
