About the Kicker 45KM42
Small speakers produce superb sound
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.
