Small but Mighty

The Kicker 45KMA6001 marine subwoofer amplifier might be small in size, but it packs a heck of a punch: 600 watts at 2 ohms, to be precise. This type of power output can drive just about any subwoofer you put into place. Even if you have a 4-ohm subwoofer, this little marvel can push out 300 watts of power. Pretty darn impressive, don’t you think?

Made for the Water

The sensitive printed circuit board in the 45KMA6001 monoblock amplifier has a conformal-coating to protect it from moisture. This allows the amplifier to thrive in an environment that would quickly kill off an amplifier not intended for marine use. If you put the right pieces in-place, you’re going to get incredible sound as well as things that just keep working!

Lots of Tuning Options

Not only do you have the on-board low-pass crossover, bass boost, input level control, and gain to fool with when getting the connected subwoofer to sounds its best, the 45KMA6001 also comes with a wired remote bass knob. You can run this to a location of your choice so you can quickly and easily dial in the perfect amount of bass response to keep the good time rolling.
