Marine-Grade Design

The 45KMA3004 4-channel marine amplifier from Kicker features conformal-coated printed circuit board to protect the delicate board from the moisture found out on the waters. The last thing you want to happen to your music when you’re out fishing or motoring about is for it to go out on you. The 45KMA3004 is designed to withstand the elements and to come out on top.

Versatility is the Name of the Game

Don’t be fooled by the 4-channel 45KMA3004 amplifier: sure, it can power a couple pairs of speakers quite well, but when you begin to expand your system, the amplifier can be reconfigured to instead power a pair of speakers and a small 4-ohm subwoofer. If you have a power-hungry set of speakers, you can bridge the amplifier into 2-channel mode and push out 150 watts to the pair of speakers. As your needs change, this amplifier can be reconfigured to meet that current need!

Extra Bump

This amplifier also features KickEQ™ bass boost technology so you can add some more impact from the attached speakers or subwoofer. One of the hardest sounds to reproduce on a boat is bass response, so the 45KMA3004 does all that it can to help you get it.

Looking for a different amplifier configuration? The Kicker 45KMA-series is also available in a monoblock, 2-channel, or 6-channel design.
