Kicker Marine 45KMA4506 6-Channel Amplifier
Kicker’s 45KMA4506 marine amplifier can power six speakers with 40 watts RMS each, so you’ll hear your music clearly over the sounds of the wind and waves, in up to 3 zones on your boat.
You could also use this amp to power a system consisting of two speakers for the deck, for example, and two speakers plus a subwoofer for the cabin.
If you’re just interested in power, this amp can go into a bridged, 3-channel mode and put out up to 150 watts RMS per channel, for two high-performance tower speakers and a sub, for example.
